Best Cloud Mining Pools For Bitcoins Wikipedia

Bitcoin mining is so-called because it resembles the mining of other commodities:it requires exertion and it slowly makes new units available to anybody who wishes to take part. An important difference is that the supply does not depend on the amount of mining. In general changing total miner hashpower does not change how many bitcoins are created over the long term.
Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.
Early Bitcoin client versions allowed users to use their CPUs to mine. The advent of GPU mining made CPU mining financially unwise as the hashrate of the network grew to such a degree that the amount of bitcoins produced by CPU mining became lower than the cost of power to operate a CPU. The option was therefore removed from the core Bitcoin client's user interface.
As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts. This made mining something of a gamble. To address the variance in their income miners started organizing themselves into pools so that they could share rewards more evenly. See Pooled mining and Comparison of mining pools.
The following pools are known or strongly suspected to be mining on top of blocks before fully validating them with Bitcoin Core 0.9.5 or later. Miners doing this have already lost over $50,000 USD during the 4 July 2015 fork and have created a situation where small numbers of confirmations are much less useful than they normally are.
This is a list of for-profit companies with notable commercial activities related to bitcoin. Common services are cryptocurrency wallet providers, bitcoin exchanges, payment service providers[a] and venture capital. Other services include mining pools, cloud mining, peer-to-peer lending, exchange-traded funds, over-the-counter trading, gambling, micropayments, affiliates and prediction markets.
getblocktemplate moves block creation to the miner, while giving pools a way to set down the rules for participation.While pools can do just as much as they could before by expressing it in these rules, miners can not be kept in the dark and are enabled to freely choose what they participate in mining.This improves the security of the Bitcoin network by making blocks decentralized again.
In February of 2012, Luke implemented and deployed a first draft of getmemorypool mining support in Eloipool (and on Eligius) along with a proof-of-concept getwork proxy (now known as gmp-proxy), adding revisions as needed to function as a general-purpose decentralized mining protocol.After he had confirmed it was working, he documented and proposed it on the Bitcoin development mailing list for review on February 28th, where discussion began on what was missing and what needed to be changed or clarified.During the following few months, a number of others, both developers and testers, provided constructive criticism and suggestions, which were integrated into the standard.Luke also actively encouraged participation in the development of the standard among pool operators and poolserver authors, especially as it became necessary to move forward into the ASIC "mining generation".Eventually, it was decided it would be best to rename it to the more appropriate "getblocktemplate" name and drop backward compatibility with getmemorypool for simplicity.The standard was split into two pieces and the technical specification can be found in BIP 22 and BIP 23.
Change addresses lead to a common usage pattern called the peeling chain. It is seen after a large transactions from exchanges, marketplaces, mining pools and salary payments. In a peeling chain, a single address begins with a relatively large amount of bitcoins. A smaller amount is then peeled off this larger amount, creating a transaction in which a small amount is transferred to one address, and the remainder is transferred to a one-time change address. This process is repeated - potentially for hundreds or thousands of hops - until the larger amount is pared down, at which point (in one usage) the amount remaining in the address might be aggregated with other such addresses to again yield a large amount in a single address, and the peeling process begins again[5].
Mining is the most anonymous way to obtain bitcoin. This applies to solo-mining as mining pools generally know the hasher's IP address. Depending on the size of operation mining may use a lot of electrical power which may attract suspicion. Also the specialized mining hardware may be difficult to get hold of anonymously (although they wouldn't be linked to the resulting mined bitcoins).
You've heard of Bitcoin and you're ready to get your hands on some digital wealth. However, this may be easier said than done. When you "mine" Bitcoin, you actually verify Bitcoin transactions in the public, decentralized ledger of Bitcoin transactions (called the blockchain). Every time you find a new block to add to the chain, the system gives you some Bitcoin as a reward. Back in the early days of Bitcoin, it was easy to mine Bitcoin using your own computer. However, as the cryptocurrency has become more popular, it has become all but impossible for individuals to make a profit mining Bitcoin. That doesn't stop a lot of people from trying, though. If you want to mine Bitcoin, you can either sign up with a cloud-mining company or build your own mining rig to mine for yourself.[1]XResearch source
The RfC refers to the Cambridge Bitcoin Electricity Consumption Index and Digiconomist's Bitcoin Energy Consumption Index (and the similar one about Ethereum). Both of those calculate the total energy consumption of the Bitcoin (or Ethereum) network. Digiconomist divides that by the number of transaction and calls that "cost of a transaction". IANE but I don't think that's a meaningful number. The proof-of-work process in which a new block is added to the blockchain is very computationally expensive (Bitcoin's security model is based on many miners competing to be the first to solve a very hard computational puzzle that's required for adding a block; an attacker would have to outperform all of them, which has prohibitive electricity costs). Transactions are not computationally expensive so the WMF increasing the total number of Bitcoin transactions by accepting Bitcoin donations would cause approximately zero environmental burden. Miners get a fee for validating transactions, which might incentivize more people to invest into mining and thus increase the burden on the environment; but those fees are fairly small compared to the income miners directly get from creating blocks (the one who wins the race and is allowed to create the next block gets a few newly created bitcoins) - the ratio is not constant but fees are around 1-2% of direct rewards most of the time, so probably aren't a significant influence on miners.
The environmental impact of bitcoin mining is a valid concern, but most important is the fact that cryptocurrencies are only two things: a tool for illegal payments and money laundering, and the object of the biggest ponzi scheme in history.
The requirement of decentralization has a very high negative impact on all aspects of a payment system -- including transaction cost, speed, capacity, safety, value stability, and convenience. Those disadvantages mean that cryptocurrencies are absolutely laughable as payment systems for legal commerce. Suffices to say that the Visa network processes 40'000 payments per second, confirms in less than 15 seconds, and costs less than $0.20 per transaction; whereas the bitcoin network cannot process more than 4 payments per second, takes 10 minutes or more to confirm, and costs more than $50 per transaction (which is paid by investors, not users). These are not implementation flaws that could be solved in time: they are unavoidable consequences of decentralization.
Criminals of all sorts love bitcoin, because it is the only online payment system that they can use which does not comply with the "know your customer" (KYC) and "anti money laundering" (AML) laws that existing systems must comply. THAT is the only advantage of decentralization. Thank to that "quality", bitcoin is the single reason why ransomware grew from a practically unknown risk to the major form of cybercrime, both in number of victims and in monetary value.
As an investment, all cryptocurrencies are negative-sum gambling games. All investors expect to get back the money invested with fat profit; however, any money that they may take out comes from only one source: new investment money. That is the very definition of ponzi scheme. There is no other source of money that can get back to them, but there is a big sink: the money collected by miners, which is not about 30 million USD per day.
An easy estimate says that people have spent about 20 billion USD more buying bitcoins than they received selling them. That deficit will never decrease; it will only increase, as long as the price is greater than zero.
Those who insist that Wikimedia accept bitcoin donations are not doing so because they intend to donate. Bitcoin believers will not part with their precious coins, which they are sure will be worth 10x or 1000x more "some day". They only want to use Wikimedia to make bitcoin more respectable -- because they know that their profit depends on more people investing in it.

This worked quite well early on. However, proof-of-work algorithms benefit from economies of scale, which leads to centralization directly. So as mining became more difficult and demanded more specialized resources, single mining "pools" became a substantial fraction of Bitcoin's network hashrate. In June 2014, mining pool GHash reached 51%, leading to calls to use decentralized pooling options.[55] In 2015, nine mining pools controlled 75% of the hashpower.[56]
