How Bitcoin Mining Works

Before you start mining Bitcoin, it’s useful to understand what Bitcoin mining really means. Bitcoin mining is legal and is accomplished by running SHA256 double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. The speed at which you mine Bitcoins is measured in hashes per second.

The Bitcoin network compensates Bitcoin miners for their effort by releasing bitcoin to those who contribute the needed computational power. This comes in the form of both newly issued bitcoins and from the transaction fees included in the transactions validated when mining bitcoins. The more computing power you contribute then the greater your share of the reward.

Sometimes you may want to mine a more volatile altcoin like MWC which is superior for scalability, privacy, anonymity and fungibility by utilizing MimbleWimble in the base layer.

With mainnet launching in November 2019 it has risen from $0.22 to over $8.00 in its first two months.

Free Bitcoin Mining – Cloud Miners

Cryptotab Browser – Editor’s Choice

Alright, this is not really a mining website, but actually a browser software that allows trickle mining in the background. The browser is a Chromium variant, so Chrome users will have no trouble migrating to this new browser.

Please note this browser is actually mining on your local PC, so it will consume CPU power of your machine. The hash power is not too much, its mostly less than 100 H/s, which means you may make just 1-2 satoshi in 10 min. based on current complexity and BTC trends.

I know, this is too slow and tedious, but it is a natural mining process and the most effective mining – trust me. Unlike others, you can expect this miner to be a long haul.

Be cautioned that using browser mining for long hours, on home laptops can be bad for the machine’s life. Fortunately, the software has the option to throttle how much CPU power can be used. I suggest keeping it below 40% so as to have a longer computer life. Or better rent a cheap VPS, and run the miner there, because servers are much more resilient to continuous utilization.

Dualmine / AbsolutMining

Thanks to Anto for mentioning these. This cloud miner provides a whopping 100 GH/s for free on signup. But unlike other sites, the contract is for 1 year only. Still its a good free investment.

In addition, there are other time-sensitive promotional offers that allow racking up more power in free mining. The prices are pretty decent, and you may rack up 3x more hash power on every purchase, before the promotion ends.

For AbsolutMining, there is a 500 GH/s bonus, for approved Youtube channel owners with 500+ subscribers.

Bitfire Mining

This cloud miner gives a trial 100 GH/s miner share for 1 week. Ah! I know that is like a tickle rite? Anyway, if you purchase a contract, then you are eligible for bonus program, that gives away free coins every 8 hours. You can also increase you levels, which improves your chance of higher payout. Also, in future, higher level users will be able to participate in weekly raffles, will have access to special discounts, etc.

Eobot

This cloud miner has been around for a while since 2013, and provides many alt coins including bitcoin mining, that can be purchased for share investment. You do not get any free hashes here, but the site also has a faucet page, where free bitcoin can be earned daily, for just visiting and completing captcha. When you accumulate sufficient balance, go ahead and purchase a cloud mining share.

In addition, if you are tech savvy, you may join their mining pool, by running software miners on your own PC or VPS. Purchases are only in cryptocurrency as of now, so no credit cards, etc.

Mining Centralization

Pools and specialized hardware has unfortunately led to a centralization trend in Bitcoin mining.

Bitcoin developer Greg Maxwell has stated that, to Bitcoin’s likely detriment, a handful of entities control the vast majority of hashing power.

It is also widely-known that at least 50% of mining hardware is located within China.

However, it’s may be argued that it’s contrary to the long-term economic interests of any miner to attempt such an attack.

The resultant fall in Bitcoin’s credibility would dramatically reduce its exchange rate, undermining the value of the miner’s hardware investment and their held coins.

As the community could then decide to reject the dishonest chain and revert to the last honest block, a 51% attack probably offers a poor risk-reward ratio to miners.

Bitcoin mining is certainly not perfect but possible improvements are always being suggested and considered.

Red Flags to Look Out for In Cloud Mining Operations

If you believe you have found a legitimate cloud mining company, you can really make sure by putting it to the test.

If any of these red flags are present, we recommend proceeding with caution.

NOTE: the following are taken largely from Puppet’s Cloud Mining 101 reddit post, which is a great supplement to this post.

Is there a way to direct hashing power to your chosen pool?

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.

If this is not an option, it is very likely that the hashing power does not exist at all.

That said, just because a pool does allow you to redirect hashing power, does not mean it’s legitimate.

Has an ASIC manufacturer endorsed the cloud miner?

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.

For instance, Bitmain has publicly endorsed BitDeer, which does indicate that Bitmain has supplied BitDeer with ASICs.

Does the cloud miner have an affiliate program?

Cloud mining operations that offer affiliate bonuses are very suspect, especially when they are offering numbers as high as 10%. 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.

An image of a sketchy affiliate program paying way too high of referral fees

Can you find out who the owners are?

If there is no way to the know identity 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.

Hashflare lists no actual names on its ‘about us’ page.

If, for instance, Jack Dorsey or Elon Musk was an investor/founder of a cloud mining operation (and they were public about it in a verifiable way), it would speak volumes about the legitimacy of the operation because they are so wealthy and so public that they would have too much to lose by scamming a few thousand people out of a few Bitcoins.

WARNING: Just because a cloud mining website boasts a famous person as an investor or advisor does not mean that person is actually investing or advising. Anyone can throw up a picture of Elon Musk on their site. The real proof is if Elon Musk himself says in a news clip that he is a founder.

Can you sell your shares?

Investments should never be a one-way transaction. If you can easily give the cloud miner money, but there is no obvious way to sell your position and get it back, then that is a good indication you will never get your money back.

Hashflare closed all their contracts without notice.

Does the cloud miner guarantee profits?

Any investment that guarantees profits is a scam. If the cloud miner has so far made good on delivering its guarantees, it is because they are using funds from new investors to pay off old ones and appear solvent. Ponzi schemes work this way. Eventually, they are going to run with the money, but you never know when it will happen.

The other point to consider is: if a miner could guarantee profits, why would they sell that right to you? Why wouldn’t they take the guaranteed profits for themselves?

Is there an unlimited amount of hashrate for sale?

If the amount of shares for sale in the cloud mining operation appear infinite, then they are definitely running a scam. No miner has an unlimited amount of hashing power. If they did, they could just 51% attack the network of their choosing.

Conclusion

Whether it be free or paid cloud mining, always take your time in picking a decent host. One of the ways to do this is to look at their security measurements. Some companies offer poor security or even have a reputation of being broken into or hacked in the past.

In such cases, it doesn’t matter if those companies’ hash rates are through the roof or if it offers the prettiest interfaces — they’re not trustworthy.

If all of your profits and earnings get stolen, it doesn’t matter what the site looks like, right? Well, imagine if you had paid for a cloud mining service. In this case, you would risk not only losing your cryptocurrency, but also your credit card being hacked!

Keep in mind that if you want to protect your cryptocurrencies, you should choose reliable hardware wallets, such as Ledger Nano X and Trezor Model T. 

All in all, hopefully now you have a wider understanding of free cloud mining. There are a lot of options in the market — understandably, it might be difficult to pick just one. Do your research, have a critical mindset and you should be set!

What is Bitcoin Mining?

Visualize and Download High-Resolution Infographic

What is the Blockchain?

Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.

The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a «subsidy» of newly created coins.

This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.

Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

Final Verdict

While new bitcoin mining software is being developed every year, only a handful grabbed our attention due to their reputation, features, and ease of use.

At the top of our list is CGMiner, which we chose as the best overall since its open-source platform can be used on any computer and practically any mining rig.

Advanced users will like BFGMiner, our choice as the best for customization, because of its ability to detect and start idle threads and mine multiple cryptocurrencies, while novices will enjoy MultiMiner’s friendly graphical user interface (GUI) and automated hardware detection and mining features, which make it our pick as the best for ease of use.

Finally, we choose Awesome Miner as the best centralized management since it’s compatible with popular mining algorithms and lets users manage multiple rigs and miner’s pools all from one comprehensive dashboard.

Как и с чего начать майнить биткоины

Именно этот вопрос самый востребованный — с чего же стоит начинать заработок криптовалюты? И в первую очередь стоит понимать – с чего, с какого именно оборудования стоит стартовать новичку?

С первыми специальными чипами — ASIC, которые считывают электронные единицы, сам процесс вычисления многократно ускорился. При этом добыча криптовалюты стала максимально безопасной. Теперь нет вмешательства из стандартной сети и гарантии слаженной работы любых цепей блоков.

Сегодня уже разработаны многие линейки этих самых АСИКов, которые доказали свою эффективность и помогают выводить на высокий уровень производства криптовалюты. И тут уже стандартный ПК — не конкурент ASIC, потому актуальность их использования на рынке майнинга криптовалюты снижена.

What Is a «64-Digit Hexadecimal Number»?

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 10. This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine.

«Hexadecimal,» on the other hand, means base 16, as «hex» is derived from the Greek word for six and «deca» is derived from the Greek word for 10. 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 64-digit number (the hash). I repeat: You do not need to calculate the total value of a hash. 

So, what do «64-digit hexadecimal numbers» have to do with Bitcoin mining? 

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. Miners make these guesses by randomly generating as many «nonces» as possible, as fast as possible. A nonce is short for «number only used once,» and the nonce is the key to generating these 64-bit hexadecimal numbers I keep talking about. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is 256 bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6.25 BTC.

In theory, you could achieve the same goal by rolling a 16-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.info, might help you put all this information together at a glance. You are looking at a summary of everything that happened when block #490163 was mined. The nonce that generated the «winning» hash was 731511405. 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).

(source: Blockchain.info)

«So how do I guess at the target hash?»

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:

«How do I maximize my chances of guessing the target hash before anyone else does?»

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.

Bitcoin Mining:

We offer a list of trusted bitcoin mining companies.

We recommend cloud mining as it is prohibitively expensive for anyone to mine from home or from a non-data center. This is due to the high cost of power and the hardware that is needed. This is why the best way to earn money mining bitcoins or other crypto-currencies is to invest in cloud mining.

We currently analyze bitcoin mining companies based on these criteria:

• Hash rates offered
• Crypto-currencies offered
• Responsive customer service
• 24/7 live chat or phone support
• History of establishment
• Reputation management
• Verification of payouts from trusted unbiased third party
• Payout frequency

To safeguard your funds we recommend the following:

Investment Tips:

• Mine (invest) in more than one crypto-currency. While bitcoin is popular you should not forget about Ethereum which is in second place. Bitcoin Cash and Dash are also other popular alternatives.
• Diversify your holdings by using more than one mining company. This is the same way that you would diversify a stock portfolio. It ensures should in the unlikely event that something happens with a mining company you will not be affected as adversely.
• Avoid small bitcoin mining companies that promise the moon such as 4x return on your investment. If this was the case they would mine and keep all of the profit without needing your capital infusion.
• Choose one of the top mining companies. Many companies are only interested in stealing your money and will stop paying within a couple of months.
• Never invest with a bitcoin mining company that cold calls you or sends you an unsolicited email.

Bitcoin Debit Cards:

Bitcoin debit cards can serve as an easy alternative to setting up an offshore bank. You can invest in bitcoins and receive payments for invoices via bitcoin. You are then free to spend money or withdraw money using a bitcoin debit card. The card works like any other debit card and you have the choice of a PIN or a CHIP card.

There are two options that we recommend.

Bitpay Visa – This is the safest debit card if you want a company that is located in the United States. Bitpay is in it for the long term and they follow the letters of the law. This means they collect all customer information and report it accordingly. USA residents only.

Cryptopay – If you are more concerned about privacy than security this is a solid option. Most bitcoin enthusiasts are concerned about privacy and cryptopay is the safest option that still offers the legitimacy of a corporate entity that is located in a regulated jurisdiction. No ID verification is needed for the lower limit card.

There are many debit cards that are offered for bitcoin users. The problem is many of them are fly by night operations, whereby as soon as they receive your bitcoins the operatorss vanish. We recommend you perform due diligence especially if the outfit is located out of Eastern Europe.

Some previous scam cards are: RAXCARD and EKCash.
