But in spite of all the reasons bitcoin is advancing, the most popular cryptocurrency in the world has three fundamental flaws that, as I see it, are practically impossible to fix. One of the more common arguments from bitcoin bulls as to why it's worth so much is its perceived scarcity. As noted earlier, proofing transactions does lead to inflation in the form of However, the maximum number of bitcoin that can be produced is capped at 21 million, with With an annual bitcoin token inflation rate of just 3.
But there's a catch to this figure. Namely, there's no hard cap on the number of tokens that are in circulation. Rather, it's computer code and community consensus that determine this cap. Comparatively, a physical store of value like gold is a finite asset. The gold that's currently in the ground, or has been mined, is all there will ever be on this planet, unless some miracle form of alchemy is invented in the future.
That's in stark contrast to bitcoin, which could have its token cap adjusted based on community consensus. In short, bitcoin really isn't as scarce as people think. A second fundamental flaw with the largest cryptocurrency in the world by market cap is that it has limited utility, or use. Optimists might hail bitcoin as a replacement for cash or the anti-banking currency, but it currently lacks the utility for broad-based adoption. For starters, bitcoin's volatility is a big reason why most retailers won't accept it.
Even with blockchain-based transactions that can potentially validate and settle faster than payments on traditional banking networks, the lag in settlement times can still allow for wild vacillations in the price of bitcoin.
It should be said that while many of these companies cited volatility as a reason to drop bitcoin, variable transaction fees were noted, too. Bitcoin's Since a good chunk of these coins are being held for investment purposes by a small number of wealthy individuals and traders , and are thus out of circulation for an extended period of time, there's simply not that many coins to go around for retail transactions and payments.
Unless the bitcoin token cap was raised well beyond 21 million, bitcoin lacks the utility to spur fundamental monetary change. On one hand, there's the digital token, which is what cryptocurrency investors are buying. And on the other hand, there's the underlying blockchain, which is that aforementioned digital ledger that transparently and immutably records transactions. Blockchain is where the real evolution and innovation of the cryptocurrency movement lies. Here's the problem: Buying a cryptocurrency token bitcoin or most any other does not give investors any ownership in the underlying blockchain.
If the underlying blockchain of a crypto token becomes the basis for innovation at a particular company or within an industry, its associated token isn't necessarily going to benefit and neither will token-holders. In fact, companies are developing their own tokens for use on in-house-created blockchains, or creating token-less blockchains that work with fiat currencies, such as the U.
Although IBM is still very stodgy in nature and living off of its legacy hardware and software revenue, it's also made an effort to be on the cutting edge of blockchain projects. IBM has been working with about a dozen banks in the South Pacific to improve settlement times on its proprietary blockchain network, and set up a joint venture with shipping giant Maersk in early to develop blockchain-based shipping solutions to revolutionize supply chain management.

This process is also known as proof of work. The good news: No advanced math or computation is involved. You may have heard that miners are solving difficult mathematical problems—that's not exactly true. It's basically guesswork. The bad news: It's guesswork, but with the total number of possible guesses for each of these problems being on the order of trillions, it's incredibly arduous work.
In order to solve a problem first, miners need a lot of computing power. That is a great many hashes. If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site Cryptocompare offers a helpful calculator. In addition to lining the pockets of miners and supporting the bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency.
For example, as of Nov. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin. There will eventually come a time when Bitcoin mining ends; per the Bitcoin Protocol, the total number of bitcoins will be capped at 21 million. This does not mean that transactions will cease to be verified.
Miners will continue to verify transactions and will be paid in fees for doing so in order to keep the integrity of Bitcoin's network. Aside from the short-term Bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol.
The rewards for bitcoin mining are reduced by half every four years. When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC. By , this was halved again to If you want to keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real-time.
Interestingly, the market price of bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and historically the price has risen with it.
Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem.
For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for Bitcoin, the difficulty level of mining increases in order to keep block production at a stable rate.
Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in the initial difficulty level was one. As of Nov. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC. The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring fans.
Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money. The ins and outs of bitcoin mining can be difficult to understand as is. And there is no limit to how many guesses they get.
Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right answer.
In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but who haven't verified the most transactions are not rewarded with bitcoin.
Well, here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal.
As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine. In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f. If you are mining bitcoin, you do not need to calculate the total value of that digit number the hash.
I repeat: You do not need to calculate the total value of a hash. Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope? In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about.
In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on earth would you want to do that?
The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block was mined. The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below.
As you see here, their contribution to the Bitcoin community is that they confirmed transactions for this block. If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros.
There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. You'd have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined bitcoin.
Mining pools are comparable to those Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes.
Not great odds if you're working on your own, even with a tremendously powerful mining rig. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem. They must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution. All told, bitcoin mining is largely unprofitable for most individual miners as of this writing.
Source: Cryptocompare. Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion of the total mining power on the network.
They have to use their computing power to generate the new bitcoins. Because only a when a transaction has been included in a block is it officially embedded into Bitcoin's blockchain. Distributed hash power spread among many different miners keeps Bitcoin secure and safe.
Well, you can do it. However, it's not profitable for most people as mining is a highly specialized industry. Most people should NOT mine bitcoins today. If you aren't sure which one to buy, our best bitcoin wallets guide will help you select a wallet. When earning bitcoins from mining, you may need to sell the coins to pay for power costs.
You may also need to buy coins on exchanges. Investments are subject to market risk, including the loss of principal. You will earn less than one penny per year and will waste money on electricity. This video from shows how difficult it is to make money mining using GPUs, and this was in It is far less profitable today than it was in Without a mining pool, you would only receive a mining payout if you found a block on your own.
This is called solo mining. By joining a mining pool you share your hash rate with the pool. Once the pool finds a block you get a payout based on the percent of hash rate contributed to the pool. Buying bitcoin is the fastest way. Our exchange finder makes it easy to find an exchange.
Try it here. Bitcoin mining software is how you actually hook your mining hardware into your desired mining pool. Consult local counsel for further assistance in determining whether Bitcoin mining is legal and the tax implications of doing the activity. Like other business, you can usually write off your expenses that made your operation profitable, like electricity and hardware costs. I say rough idea because many factors related to your mining profitability are constantly changing.
Using mining software for Android you can mine bitcoins or any other coin. Android phones simply are not powerful enough to match the mining hardware used by serious operations. So, it might be cool to setup a miner on your Android phone to see how it works. Enterprising coders soon discovered they could get more hashing power from graphic cards and wrote mining software to allow this. Nowadays all serious Bitcoin mining is performed on ASICs, usually in thermally-regulated data-centers with access to low-cost electricity.
Economies of scale have thus led to the concentration of mining power into fewer hands than originally intended. Pools are groups of cooperating miners who agree to share block rewards in proportion to their contributed mining power.
Today there are very professional industrial mining operations. Let's take a look at how they work. Bitcoin mining farms exclusively use ASIC miners to mine various coins. Many of these farms are minting several Bitcoins per day. By far, the biggest factor affecting how much money a mining farm makes is how much it pays for electricity. Nearly all mining farms are using the same hardware.
Since the reward for finding a block is fixed, and the difficulty is adjusted based on total processing power working on finding blocks at any given time, then electricity is the only cost that is variable. If you can find cheaper power than other miners, you can afford to either increase the size of your mining operation, or spend less on your mining for the same output.
As previously mentioned, mining farms use a lot of electricity. How much they consume depends on how big their operation is. In total, it is estimated that all mining farms will use about 75 terrwat hours of electricity in the year That is roughly the equivalent to 15 times the yearly energy consumption of denmark.
Mining farms are located all over the world. We don't know where every mining farm in the world is, but we have some educated guesses. Most of the mining has been and still is located in China. Why is so much Mining happening in China? The main advantages of mining in China are faster setup times and lower initial CapEx which, along with closer proximity to where ASICs are assembled, have driven industry growth there. In this bonus chapter, we will learn about some of the most common terms associated with bitcoin mining.
If you are thinking about mining at any level, understanding what these terms means will be crucial for you to get started. The block reward is a fixed amount of Bitcoins that get rewarded to the miner or mining pool that finds a given block.
A collection of individual miners who 'pool' their efforts or hashing power together and share the blockreward. Miners create pools because it increases their chances of earning a block reward. Approximately every 4 years, the block reward gets cut in half. The first block reward ever mined was in and it it was for 50 Bitcoins. That block reward lasted for four years, where in , the first reward halving occured and it dropped to 25 Bitcoins.
In , a second halving occured where the reward was reduced to And as of the time of this writing, we are on the cusp of the third halving ETA May 11th , where the reward will be cut down to 6. You can find the most up to date estimation of exactly when the next halving will occur on our bitcoin block reward halving clock. In plain english, that just means it is a chip designed to do one very specific kind of calculation. This is opposed to GPU mining, explained below. GPU mining is when you mine for Bitcoins or any cryptocurrency using a graphics card.
This was one of the earliest forms of mining, but is no longer profitable due to the introduction of ASIC miners. Or it can refer to the total amount of hashing done on a chain by all miners put together - also known as "Net Hash". Measured in Trillions, mining difficulty refers to how hard it is to find a block. The current level of difficulty on the Bitcoin blockchain is the primary reason why it is not profitable to mine for most people.
Bitcoin was designed to produce block reliably every 10 minutes. Because total hashing power or Net Hash is constantly changing, the difficulty of finding a block needs to adjust proportional to the amount of total hashing power on the network.
In very simple terms, if you have four miners on the network, all with equal hashing power, and two stop mining, blocks would happen ever 20 minutes instead of every ten. Therefore, the difficulty of finding blocks also needs to cut in half, so that blocks can continue to be found every 10 minutes. Difficulty adjustments happen every 2, blocks. This should mean that if a new block is added every 10 minutes, then a difficulty adjustment would occur every two weeks.
The 10 minute block rule is just a goal though. Some blocks are added after more than 10 minutes. Some are added after less. Its a law of averages and a lot if left up to chance. That doesn't mean that for the most part, blocks are added reliably every 10 minutes.
A measurement of energy consumption per hour. Most ASIC miners will tell you how much energy they consume using this metric. As Bitcoin could easily replace PayPal, credit card companies, banks and the bureaucrats who regulate them all, it begs the question:. If only 21 million Bitcoins will ever be created, why has the issuance of Bitcoin not accelerated with the rising power of mining hardware?
Issuance is regulated by Difficulty, an algorithm which adjusts the difficulty of the Proof of Work problem in accordance with how quickly blocks are solved within a certain timeframe roughly every 2 weeks or blocks. Difficulty rises and falls with deployed hashing power to keep the average time between blocks at around 10 minutes. For most of Bitcoin's history, the average block time has been about 9. Because the price is always rising, mining power does come onto the network at a fast speed which creates faster blocks.
However, for most of the block time has been around 10 minutes. This is because Bitcoin's price has remained steady for most of Satoshi designed Bitcoin such that the block reward, which miners automatically receive for solving a block, is halved every , blocks or roughly 4 years.
To successfully attack the Bitcoin network by creating blocks with a falsified transaction record, a dishonest miner would require the majority of mining power so as to maintain the longest chain. Pools and specialized hardware has unfortunately led to a centralization trend in Bitcoin mining.
Bitcoin mining is certainly not perfect but possible improvements are always being suggested and considered. Green sends 1 bitcoin to Red. A full node is a special, transaction-relaying wallet which maintains a current copy of the entire blockchain. If there are no conflicts e. At this point, the transaction has not yet entered the Blockchain.
Red would be taking a big risk by sending any goods to Green before the transaction is confirmed. So how do transactions get confirmed? This is where Miners enter the picture. Miners, like full nodes, maintain a complete copy of the blockchain and monitor the network for newly-announced transactions. In either case, a miner then performs work in an attempt to fit all new, valid transactions into the current block. Acceptable blocks include a solution to a Proof of Work computational problem, known as a hash.
The more computing power a miner controls, the higher their hashrate and the greater their odds of solving the current block. But why do miners invest in expensive computing hardware and race each other to solve blocks? And what is a hash? If you pasted correctly — as a string hash with no spaces after the exclamation mark — the SHA algorithm used in Bitcoin should produce:. So, a hash is a way to verify any amount of data is accurate. To solve a block, miners modify non-transaction data in the current block such that their hash result begins with a certain number according to the current Difficulty , covered below of zeroes.
If other full nodes agree the block is valid, the new block is added to the blockchain and the entire process begins afresh. Red may now consider sending the goods to Green. You may have heard that Bitcoin transactions are irreversible, so why is it advised to await several confirmations? The answer is somewhat complex and requires a solid understanding of the above mining process:. There are now two competing versions of the blockchain! Which blockchain prevails? Quite simply, the longest valid chain becomes the official version of events.
A loses his mining reward and fees, which only exist on the invalidated A -chain. The more confirmations have passed, the safer a transaction is considered. This is why what is known as '0-conf' or "0 confirmations" on the Bitcoin Cash blockchain is so dangerous. A company can claim to be a cloud mining company without any proof of actually owning any hardware.
Note: If you do find a legitimate one, you'll need a wallet to receive payouts to. A secure hardware wallet like the Ledger Nano X is a good option. It depends what your goals are with cloud mining. If your goal is to obtain bitcoins, then there is really no reason to cloud mine or even mine at all. If you find a legitimate cloud mining operation and you are making profit, you will very likely need to pay taxes on that profit.
The best way to determine the taxes you owe is to use a crypto tax software. The reason there are so many cloud mining scams is because it is very easy for anyone in the world to setup a website. The company can act legit by sending initial payments to its customers.
But after that it can just keep the already received payments for hash power and then make no further payments. Two of the most famous cloud mining companies have already been exposed as scams: HashOcean and Bitcoin Cloud Services. Even as recently as September of , cloud mining scams are stealing people's money.
The SEC equivalent of the Phillipines just issued a warning to customers of Mining City to get out now and have told promoters of the company that they could go to jail for up to 21 years if they don't stop immedietely. Cloud mining scams are not a thing of the past. They very much so still happen today, so be vigilant or, better yet, just avoid them.
If you beleive you have found a legitimate clound mining company, you can really make sure by putting it to the test. NOTE: the following are taken largely from Puppet's Cloud Mining reddit post, which is a great supplement to this post. If you have purchased options for the right to some amount of hashing power, there is no reason why you shouldn't be able to direct that hashing power to any pool that you want. There are only a handful of ASIC manufacturers who could service a large scale mining operation with hardware.
Any cloud mining operation would not only allow an ASIC manufacturer to disclose a large ASIC purchase, but they'd also want them to do so to prove they are serious. So far, no cloud mining operation we are aware of has has an ASIC manufacturer acknowledge they are selling hardware to a cloud mining company.
Bitcoin mining is very competitive and has incredibly thin margins. There would be no way to mine profitably if they were paying not only you, but also the person who referred you. If there is no way to the know idenntity of the cloud mining operation, there is no way to hold them accountable if they run with the money.
It also makes it harder to catch the person who stole your money.
