Is Bitcoin Mining Profitable or Worth it in 2018? The early days of Bitcoin mining are often described as a gold rush. Those with a strong any Way To Buy Bitcoin Litecoin Mining Rig in such things, namely cypherpunks, cryptographers, technically-minded libertarians and assorted hackers, were first to stake their claim.
But is there still gold in them thar hills? Bitcoin mining has grown from a handful of early enthusiasts into a cottage industry, into a specialized industrial-level venture. The easy money was scooped out a long time ago and what remains is buried under the cryptographic equivalent of tons of hard rock. Only those with specialised, high-powered machinery are able to profitably extract bitcoins nowadays. While mining is still technically possible for anyone, those with underpowered setups will find more money is spent on electricity than is generated through mining.
In other words, mining won’t be profitable at a small scale unless you have access to free or really cheap electriciy. A new block is created on average every ten minutes. Proof of Work Hashing: This is the cryptographic work which miners perform in order to find the solution which allows them to define a new block. PoW hashing ensures the proper function of the Bitcoin blockchain. There are no shortcuts in this process, which can only be solved with raw computational power.
By correctly hashing the current block, miners prove their investment of work and are rewarded with a certain number of newly-created bitcoins. The number of newly-created bitcoins, awarded to whichever miner creates a block. This number was initially set to 50, halved to 25 in late-2012, and halved again to 12. The next halving event expected is around mid-2020. 210,000 blocks, until all 21 million bitcoins are created.
Hashrate: Hashrate is the measure of a miner’s computational power. In early 2017, Bitcoin’s collective hashrate reached nearly 4 Exahash. D of such hardware, and electrical expenditure. Difficulty: With hashrate shooting up over the years, it would seem blocks would be found by miners ever more rapidly. Bitcoin’s Difficulty measure is what prevents this from happening. It adjusts to hashrate to ensure that blocks are found roughly every 10 minutes. Note how closely Difficulty matches Hashrate in the 2 charts above.

Electricity is the major on-going cost of Bitcoin mining. The price paid per Watt will greatly influence profitability. By banding together with other miners in a so-called pool, your combined odds of solving a block rise proportional to the pool’s total hashrate. The future profitability of mining cannot be reliably predicted. This is due to the ever-changing nature of the Difficulty modifier and the BTC price, in particular. To begin, we must select a suitable ASIC mining rig.
It’s pretty much the cutting edge of mining tech so we’ll select it for our example. 120 or so to the price. Next, we need to enter the S9’s specs and cost, as well as other info such as power cost and pool fees, into a suitable number-cruncher. BTC price, Difficulty and block reward info.
Note that the Hardware Costs field does not seem to influence the final calculation. Chinese industrial area or one in which electricity is subsidized. To determine your own power cost, check worldwide electricity prices or your utility bill for the exact price. Pool Fee assumes a mining farm large enough to run its own pool. Smaller pools will generally offer lower or even no fees, but keep in mind they will seldom find blocks. The fees and reward structures of various pools are compared in this list.
As a large miner would be able to negotiate a lower unit price on each S9, we can assume they’ll research profit even sooner. It’s not looking so great now. 1348 a year, assuming difficulty and price hold steady. In other words, the unit will pay for itself within a year.
Therefore, any calculations should be regarded skeptically, as likely best-case scenarios. Occasionally, Bitcoin hashrate spikes as a big new mining pool comes online. It’s quite possible that even some big, corporate miners found their profit margins under threat from the resulting steep spike in competition. Indeed, in mid-2016, Swedish Bitcoin mining firm KnCMiner declared bankruptcy. Also bear in mind that the rate of obsolescence in Bitcoin mining hardware is quite fast! New, more efficient mining hardware may be released at any time, although we are reaching the technological limits of improved efficiencies.
Such downside risks must always be factored into any sound business plan. Conclusion The average home miner will struggle to be profitable or recoup the cost of mining hardware and electricity. Profitability is highly unlikely given the current circumstances. The situation may improve in future once ASIC mining hardware innovation reaches the point of diminishing returns. That, coupled with cheap, hopefully sustainable power solutions may once again make Bitcoin mining profitable to small individual miners around the world.
This would also greatly improve the decentralization of the Bitcoin network, hardening it against legislative risk. Get the latest Bitcoin news and analysis.

One Email a Day, 7 Days in a Row. What Is Bitcoin Mining and Is It Profitable in 2018? The following post will give you an in-depth understanding of what Bitcoin mining is, how it works, and—most importantly—whether it’s still profitable today. I’ll do my best to keep it simple, as always.
What is Bitcoin mining and how does it work? Why do we even need Bitcoin mining? Bitcoin is a decentralized alternative to the banking system. This means that the system can operate and transfer funds from one account to the other without any central authority. With a trusted central authority, transferring money is easy. 50 from your account and add it to someone else’s account. In this example, the bank has all the power because the bank is the only one that is allowed to update the ledger that holds the balances of everyone in the system.
But how do you create a system that has a decentralized ledger? How do you give someone the ability to update the ledger without giving them too much power—in case they become corrupt or negligent in their work? Who Wants to Be a Banker? How Bitcoin mining works In short, anyone who wants to participate in updating the ledger of Bitcoin transactions, known as the blockchain, can do so. All you need is to guess a random number that solves an equation generated by the system.
Of course, this guessing is all done by your computer. The more powerful your computer is, the more guesses you can make in a second, increasing your chances of winning this game. Here’s a more detailed breakdown of the mining process: 1. Once your mining computer comes up with the right guess, your mining program determines which of the current pending transactions will be grouped together into the next block of transactions. The block you’ve created, along with your solution, is sent to the whole network so other computers can validate it. It’s a bit similar to a Rubik’s cube: The solution is very hard to achieve but very easy to validate.
Each computer that validates your solution updates its copy of the Bitcoin transaction ledger with the transactions that you chose to include in the block. Additionally, you get paid any transaction fees that were attached to the transactions you inserted into the next block. All the transactions in the block you’ve just entered are now confirmed by the Bitcoin network and are virtually irreversible. Here’s a two-minute video showing the process of blocks and confirmations.
So that’s Bitcoin mining in a nutshell. But if you think about it, the mining part is just a by-product of the transaction confirmation process. So the name is a bit misleading, since the main goal of mining is to maintain the ledger in a decentralized manner. As you can imagine, since mining is based on a form of guessing, for each block, a different miner will guess the number and be granted the right to update the blockchain.
Of course, the miners with more computing power will succeed more often, but due to the law of statistical probability, it’s highly unlikely that the same miner will succeed every time. Satoshi Nakamoto, who invented Bitcoin, crafted the rules for mining in a way that the more mining power the network has, the harder it is to guess the answer to the mining math problem. So the difficulty of the mining process is actually self-adjusting to the accumulated mining power the network possesses. This is known as mining difficulty.
Why on earth did Satoshi do this? Well, he wanted to create a steady flow of new bitcoins into the system. In a sense, this was done to keep inflation in check. Now, remember, this is on average. We can have two blocks being added minute after minute and then wait an hour for the next block. In the long run, this will even out to ten minutes on average.

The evolution of Bitcoin miners When Bitcoin first started out, there weren’t a lot of miners out there. Bitcoin back in 2009, since mining difficulty was low. As Bitcoin started to catch on, people looked for more powerful mining solutions. Gradually, people moved to GPU mining. GPUs were originally intended to allow gamers to run computer games with intense graphics requirements.
Because of their architecture, they became popular in the field of cryptography, and around 2011, people also started using them to mine bitcoins. For reference, the mining power of one GPU equals that of around 30 CPUs. Another evolution came later on with FPGA mining. FPGA is a piece of hardware that can be connected to a computer in order to run a set of calculations.
The downside is that they’re harder to configure, which is why they weren’t as commonly used in mining as GPUs. Finally, around 2013, a new breed of miner was introduced: the ASIC miner. ASIC stands for application specific integrated circuit, and these were pieces of hardware manufactured solely for the purpose of mining Bitcoin. Unlike GPUs, CPUs, and FPGAs, they couldn’t be used to do anything else. Their function was hardcoded into the machine.
Today, ASIC miners are the current mining standard. Some early ASIC miners even appeared in the form of a USB, but they became obsolete rather quickly. Even though they started out in 2013, the technology quickly evolved, and new, more powerful miners were coming out every six months. After about three years of this crazy technological race, we finally reached a technological barrier, and things started to cool down a bit. Since 2016, the pace at which new miners are released has slowed considerably. Bitcoin mining pools Assuming you’re just entering the Bitcoin mining game, you’re up against some heavy competition. Even if you buy the best possible miner out there, you’re still at a huge disadvantage compared to professional Bitcoin mining farms.
That’s why mining pools came into existence. Once the pool manages to win the competition, the reward is spread out between the pool members depending on how much mining power each of them contributed. Today there are over a dozen large pools that compete for the chance to mine Bitcoin and update the ledger. Hash rate: A Hash is the mathematical problem the miner’s computer needs to solve. Bitcoin reward per block: The number of Bitcoins generated when a miner finds the solution. The current number of bitcoins awarded per block is 12. The last block-halving occurred in July 2016, and the next one will be in 2020.
Mining difficulty: A number that represents how hard it is to mine bitcoins at any given moment considering the amount of mining power currently active in the system. Electricity cost: How many dollars are you paying per kilowatt? You’ll need to find out your electricity rate in order to calculate profitability. This can usually be found on your monthly electricity bill. Power consumption: Each miner consumes a different amount of energy. You’ll need to find out the exact power consumption of your miner before calculating profitability.
This can be found easily with a quick search online or through this list. Power consumption is measured in watts. Bitcoin’s price: Since no one knows what Bitcoin’s price will be in the future, it’s hard to predict whether Bitcoin mining will be profitable. If you are planning to convert your mined bitcoins to any other currency in the future, this variable will have a significant impact on profitability. Difficulty increase per year: This is probably the most important and elusive variable of them all. The idea is that since no one can actually predict the rate of miners joining the network, neither can anyone predict how difficult it will be to mine in six weeks, six months, or six years from now. In fact, in all the time Bitcoin has existed, its profitability has dropped only a handful of times—even at times when the price was relatively low.

Bitcoins you will earn each month. If you can’t get a positive result on the calculator, it probably means you don’t have the right conditions for mining to be profitable. How to mine Bitcoins at home: A step-by-step guide Now you know all you need to know about Bitcoin mining! Wanna know how to actually mine? Find out if mining is profitable Before even starting out with Bitcoin mining, you need to do your due diligence. The best way to do this, as we’ve discussed, is through the use of a Bitcoin mining calculator. Bear in mind that mining costs money!
If you don’t have a few thousand dollars to spare on the right miner, and if don’t have access to cheap electricity, mining Bitcoin might not be for you. Get your miner Once you’re done with your calculations, it’s time to get your miner! Make sure to go over our Bitcoin mining hardware reviews to understand which miner is best for you, if you haven’t done it already in step 1. Get a Bitcoin wallet You’ll need a Bitcoin wallet in which to keep your mined Bitcoins. Once you have a wallet, make sure to get your wallet address.
It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address, but most wallets are pretty straightforward about it. For a complete tutorial on Bitcoin wallets, watch this video. Find a mining pool When you join a mining pool, you’ll be given smaller and easier problems to solve. All of your combined work will make the pool more likely to solve the original problem and earn the bitcoin reward and transaction fees. The profits will be spread out throughout the pool based on contribution. Basically, you’ll make a more consistent amount of Bitcoins and will be more likely to receive a return on your investment.
What fee does the pool charge for mining and the withdrawal of funds? How easy is it to withdraw funds? What kind of stats does the pool provide? Once you are signed up with a pool, you’ll get a username and password for that specific pool, which you will use later on.
Controlling and monitoring your mining rig requires dedicated software. Depending on what mining rig you have, you’ll need to find the right software. Many mining pools have their own software, but some don’t. In case you’re not sure which mining software you need, you can find a list of Bitcoin mining software here. Start mining Connect you miner to a power outlet and fire it up. The first thing you’ll need to do is to enter your mining pool’s address, username, and password. Once this is configured, you will start collections shares, which represent your part of the work in finding the next block.
According to the pool you’ve chosen, you’ll be paid for your share of coins—just make sure that you enter your address in the required fields when signing up to the pool. Cloud mining means that you do not buy a physical mining rig but rather rent computing power from a mining company and get paid according to how much mining power you own. However, when you do the math it seems that none of these cloud mining sites are profitable. Ponzi schemes that will end up running away with your money. As a general rule of thumb, I’d suggest avoiding cloud mining altogether. If you still want to pursue this path, make sure to make the right calculations before handing over any funds.
Mining on a mobile phone Some mobile apps claim to mine Bitcoin on your phone. While in theory, this is possible, due to the low processing power phones have compared to ASIC miners, you’ll probably end up draining your phone’s battery much faster and make a very small fraction of bitcoin in return. The apps that allow this act as mining pools for mobile phones and distribute earnings according to how much work was done by each phone. Remember, mining is possible with any old computer—it’s just not worth the electricity wasted on it because the slower the computer, the smaller the chances are of actually getting some kind of reward.
For reference, mining was demonstrated in theory on a 55-year-old computer some time ago by IBM—and the result was of course, that it’s not worth it. Somewhere around 2017, the concept of web mining came to life. CPUs and use them to mine Bitcoin. CPUs in order to gain profits. However, since mining Bitcoins isn’t really profitable with a CPU, most of the sites that utilize web mining mine Monero instead. The concept of web mining is very controversial. From the site’s visitor perspective, someone is using their computer without consent to mine Bitcoins.
