Bitcoin Майнинга : What is it? : Wikipedia

Mining Computers
The rules of the incentive system dictate that those with the fastest computers make the most money. This has started a computational arms race across the world.

Most computers are capable of mining Bitcoin but aren’t efficient enough to profit (earn a reward more than the cost of the electricity required to attain it.) This is why areas with the cheapest electricity costs have the highest concentration of mining power.

GPU Mining
Nearly any computer can run crypto mining algorithms, but some are much better than others. A modern computer has a *****U (central processing unit) and a GPU (graphics processing unit). If the *****U is the brain of the computer, the GPU is the muscle used for mining.

Modern GPUs like the GTX 3080 are powerful and efficient enough to make mining profitable – even in the United States, where electricity costs are typically really high.

ASIC Computers
As Bitcoin mining grew in popularity, companies like Bitmain and Antminer emerged to build and sell specialized computers that could only perform 1 operation: mining.

These ASIC (application specific integrated circuit) computers began to dominate the network power, and people began to collect hundreds of them to start mining “farms”.

ASIC computers are so specialized that they can often only mine 1 specific cryptocurrency. You need an entirely different ASIC computer to mine Dash than to mine Bitcoin. This also means that a software update could make an ASIC computer obsolete overnight.

ASIC vs. GPU Mining
ASIC computers are entirely useless for anything other than crypto mining – but they smoke every GPU on the market. Mining with ASIC computers carries more risk than GPUs, but it’s much more cost effective. ASIC computers comprise the majority of mining power on most blockchains, including Bitcoin.

Certain miners and mining pools with the largest ASIC operations tend to centralize mining power on the network. For this reason, Ethereum and many other cryptocurrencies are designed to prevent ASICs from mining on their network. By only allowing GPU mining, it becomes much more expensive to dominate the network.

Should You Mine Cryptocurrency?
Cryptocurrency mining is not for everyone. Unless you live in China, your electricity is probably too expensive for you to turn a profit.

But don’t lose hope, there might be another way to profit off of your newfound mining knowledge.

Proof-of-stake. Ethereum 2.0 promises to eliminate the need for expensive mining equipment. Instead of a race between the miners to secure the data, miners will stake Ether in order for the right to secure a portion of the transactions.
Rent mining power. NiceHash is 1 of the largest mining pools in the world. They offer a service to rent mining power produced by machines in countries with low electricity costs. This way you can mine without ever getting technical.
Invest in the industry. This could become an option should companies such asNiceHash, Bitmain or Antminer ever become publicly traded.
The cryptocurrency industry is still *****, and mining has a long way to go before reaching maturation. Whether or not you should pursue an investment related to mining is up to your risk tolerance. Nearly any industry this new and underdeveloped is likely to contain a lot of uncertainty, but with uncertainty comes the potential for profit. Just be careful.

All the gold in the world is worth maybe $10 trillion, based on the World Gold Council’s estimate of how much gold has been mined and what the per-ounce price is. In other words, maybe 2-3% of global net worth consists of gold.(Citigroup), Blythe Masters (JPMorgan Chase), and Tom Glocer (Reuters);робот bitcoin bitcoin покупка bitcoin аккаунт криптокошельки ethereum bitcoin установка bitcoin mt4

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.bitcoin metatrader

The basic insight of Bitcoin is clever, but clever in an ugly compromising sort of way. Satoshi explains in an early email: The hash chain can be seen as a way to coordinate mutually untrusting nodes (or trusting nodes using untrusted communication links), and to solve the Byzantine Generals’ Problem. If they try to collaborate on some agreed transaction log which permits some transactions and forbids others (as attempted double-spends), naive solutions will fracture the network and lead to no consensus. So they adopt a new scheme in which the reality of transactions is 'whatever the group with the most computing power says it is'! The hash chain does not aspire to record the 'true' reality or figure out who is a scammer or not; but like Wikipedia, the hash chain simply mirrors one somewhat arbitrarily chosen group’s consensus:advcash bitcoin The rules of the incentive system dictate that those with the fastest computers make the most money.

Bitcoin mining is a highly competitive, dynamic, almost perfect market. Mining rigs can be set up and dismantled almost anywhere in the world with relative ease. Thus, market forces are constantly pushing mining activity to places and times where the marginal price of electricity is low or zero. These electricity products are cheap for a reason. Often, it’s because the electricity is difficult (and wasteful) to transport, difficult to store, or because there is low demand and high supply. Using electricity in this way is a lot less wasteful than simply plugging a mining rig into the mains indiscriminately.bitcoin zona

Gold also relies heavily on the network effect as well for its perception as a store of value, whereas industrial metals like copper don’t, since they are used almost exclusively for utilitarian purposes, basically to keep the lights on.miner bitcoin bitcoin desk

Even when multiple miners split these rewards, there is still ample incentive to pursue them. Every time a new block is mined, the successful miner receives a bunch of newly created bitcoin. At first, it was 50, but then it halved to 25, and now it is 12.5 (about $119,000 in October 2019).platinum bitcoin bitcoin cards monero address

He uses some concepts, referring to his protocol as a consensus mechanism and considering faults both in the form of attackers, as well as nodes joining and leaving the network. This is in contrast to his explicit reliance on the literature in linked time-stamping (and proof of work, as we will discuss). When asked in a mailing-list discussion about bitcoin's relation to the Byzantine Generals' Problem (a thought experiment requiring BFT to solve), Nakamoto asserts the proof-of-work chain solves this problem.35The lack of uniform regulations about bitcoins (and other virtual currency) raises questions over their longevity, liquidity, and universality.While wallet apps work well and are relatively safe, the safest option is a hardware wallet you keep offline, in a secure place. The most popular hardware wallets use special layers of security to ensure your keys are not stolen and your bitcoin is safe. But, once again, if you lose the hardware wallet your bitcoins are gone unless you have kept reliable backups of the keys.
