Who created bitcoin
computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin more quickly and make profits
bitcoin has a halving effect, that is to say, every four years, the number of bitcoin will be halved. In this way, the computing power of bitcoin will increase, that is, the difficulty of mining will increase. Under normal circumstances, mining generally refers to the use of mining machine, that is, the computer to dig. These all refer to the single operation, or the operation of the whole mine. Cloud computing power mining refers to mining with multiple people. You can participate in mining as long as you invest a small part
the usual steps of bitcoin mining are "purchase miner - deploy miner - set miner - get profit", but the deployment of miner is affected by many factors, such as electricity price, site, temperature, noise, operation and maintenance, etc. These barriers need certain conditions and knowledge to eliminate, so it gives birth to a sub mole of mining instry - cloud computing power
cloud computing power is a remote mining mode. Users purchase cloud computing power contracts through the platform, rent computing power mining, and obtain revenue regularly. The advantage of cloud mining is that users don't need to deeply understand the mining principle and various software and hardware, or buy expensive mining machines, and they don't need 24-hour maintenance. As long as they place an order, they can participate in mining, which is similar to purchasing usufruct procts
for mine owners, renting and selling the right to use the computing power for a period of time to customers at a price slightly lower than the self operated mining income can quickly return cash, purchase the latest mining machinery in advance, expand the proction scale, and win the possibility of profit in the forward market. To some extent, it can also retain mining machinery at a low currency price, transfer risk, and hedge the single risk of self operated mining business< However, compared with direct participation in mining, cloud computing power also shows the following disadvantages:
even if the platform fully displays relevant information such as mines, mining machinery, cooperation and teams, it is still difficult for users to judge the quality of computing power, real-time operation status (such as power failure, site temporary inspection) or real revenue data behind the platform
the risk of speculation in bitcoin (short-term trading to earn spread) is higher than that of Tuen bitcoin (long-term bullish), but most Tuen bitcoin investors often lack judgment on short-term price changes and "get off early". Cloud computing power brings a small amount of bitcoin income to investors every day, which is also controlling investors' frequent operation in disguised form. Therefore, for many people who like bitcoin, there will be such a saying: "it's better to dig money than to fry money"
the market opportunity of cloud computing power is to provide indivials with a more neutral way of investment. The threshold is lower than that of self built mines, the risk is lower than that of short-term operation, and the cost is lower than the market price. It also allows mines to share the costs and risks and obtain more abundant cash flow
the main risk of cloud computing power lies in the authenticity and stability of computing power behind the contract. In our long-term contact with the mining instry, the high-frequency words we hear are "pit": reasons for power failure beyond common sense, various incidents ring the transportation of mining machinery, constant interference of viruses and extortion, fluctuation of futures and tardy spot, obstacles of cross-border trade, and team ghosts that can't be prevented. Therefore, real and stable computing power is scarce to a certain extent, Behind it is often years of experience. As an information intermediary, cloud computing power platform will become its core competitiveness in how to help users select high-quality cooperative mine cooperation, design friendly and attractive procts, formulate professional and transparent instry standards, establish disaster recovery plans to deal with various risks, and provide high-quality services throughout the whole process of investment
of course, mining is a long-term development instry, and cost recovery also needs a certain period, so whether you can make money mainly depends on whether you can stick to it.
Cryptocurrency is not a tangible currency that can be carried with you, but a digital asset that can be exchanged“ The "encryption" part comes from using encryption technology for security and authentication ring a transaction
when using cryptocurrency for exchange instead of legal tender, crypto owners do not have to rely on banks to facilitate transactions, and can successfully avoid the costs of using financial institutions
generally, cryptocurrency transactions are processed and completed through the blockchain network. The blockchain is designed to be decentralized, so each computer connected to the network must successfully confirm the transaction before it can process it. Ideally, this would create a more secure transaction for all involved. It can also cause you to wait for a while; One of the big complaints about bitcoin is how long it takes to complete the transaction
domestic cryptocurrencies include bitcoin, Ethernet, Leyte and e-dinarcoin
extended data:
bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. It is a P2P form of digital currency. Bitcoin is generated through a large number of calculations according to specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation
ether coin: ether coin (a digital token of Ethereum, regarded as "bitcoin version 2.0"), can be bought and sold on the trading platform
lightcoin: lightcoin is a kind of network currency based on "point-to-point" technology, which can help users pay to anyone in the world immediately. At present, it is the second virtual currency after bitcoin's global circulation market value
reference materials:
network cryptocurrency
Digital cryptocurrency is a kind of currency that is not issued by legal tender institutions and controlled by the central bank. It is based on the open source code of a group of equations calculated by computers all over the world, and is generated by a large number of calculation processing of computer graphics card and CPU. It uses the design of cryptography to ensure the security of all aspects of currency circulation

definition of digital currency:
digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy< br />
bitcoin (BTC)
issue date: 2009
market value: US $163 billion
advantage: as the first cryptocurrency issued, bitcoin is the world's largest and most popular blockchain network and the most experienced cryptocurrency that can resist hacker attacks
disadvantage: the increasing demand brings great pressure to bitcoin network, which makes the transaction cost high. The system can only process about seven transactions per second, but its power consumption is amazing. This is mainly e to its workload proof mechanism and consensus principle, which makes mining become a labor-intensive activity
eth
release date: 2015
market value: US $70 billion
advantage: its built-in programming language allows developers to write their own smart contract computer programs running on the blockchain. So far, most of the first token sales are based on Ethereum's smart contracts
Disadvantages: Ethereum also uses the consistency protocol of workload proof, so it is relatively slow and consumes a lot of power. Many early smart contracts are vulnerable to hacker attacks, and the development of smart contract security is still immatureXRP
issue time: 2012
market value: US $32 billion
advantage: XRP claims that its XRP cryptocurrency can become the "bridge currency" of major financial institutions, and can settle cross-border payments more quickly and at lower cost. Ruibo uses a new consistency protocol, which can achieve faster transactions, faster than t-coin and Ethereum
disadvantages: as a private company, Ruibo has important control over the system, some people think that XRP is not decentralized enough, which is in contrast to bitcoin, which anyone can mine
bitcoin cash (BCH)
issue time: 2017
market value: US $19 billion
advantage: this kind of currency is a "hard fork" of bitcoin, and its founder has adjusted compared with bitcoin, so that it can handle a larger transaction volume
disadvantage: critics say bitcoin cash is too centralized - a few miners create most of the money
lightcoin (LTC)
time of issue: 2011
market value: US $10 billion
advantage: lightcoin is a kind of "alternative currency" - almost a clone of bitcoin, but there are still several differences. Lightcoin processes transactions four times faster than bitcoin, and the mining process remains open to amateurs - very different from bitcoin, because bitcoin's professional miners use expensive hardware
disadvantages: although it is faster than bitcoin, lightcoin is still too slow and consumes a lot of power. These factors make it unable to become an ideal payment method, and there is another disadvantage: it is not very famous
recommend an article: brief introction of the top 100 currencies in the market value ranking of digital currency. This article summarizes the brief introction of the top 100 currencies in the market value ranking (according to the market value ranking of coinmarket cap on July 30, 2018), hoping to be helpful to friends who have just entered the currency circle
The top three are bitcoin, Ethereum and reborn. As shown in the figure below:
of course, the token market value of crowdfunding projects on coin Ying China platform is different, and is not included in the ranking
233 small games are safe
small games do not make money. In 233 small games, the main ones related to the game business and making money are web games, such as dream journey to the west, life and death sniper, flash small games, which mainly make money by patch advertising. In addition, there are advertisements in the game page, and the exposure of cooperative brands is also one of the revenue
however, the digital currency planned by the central bank is different from bitcoin, Ruitai currency and vitality currency.
Ethereum, the world's second largest cryptocurrency, broke through $3000 for the first time on Monday, and rose further on Tuesday, once breaking through $3400, reaching a new high. Its market value once reached US $395.2 billion, ranking 18th in the global asset market value, surpassing MasterCard and NVIDIA and approaching Wal Mart. Traders attribute the rise of bitcoin to the rise of bitcoin at the end of 2020, and the upgrade of blockchain Ethernet makes bitcoin more useful. So far this year, Ethereum has grown by about 365%
bitcoin network is actually a distributed database, and Ethernet goes a step further. It can be seen as a distributed computer: the blockchain is the ROM of the computer, the contract is the program, and the miner of Ethernet is responsible for the calculation and plays the role of CPU. Of course, this computer is not and can not be used for free, otherwise anyone can store all kinds of junk information and carry out all kinds of trivial calculations
OK, that's what we're going to share in this issue
