1. It is not recommended to buy cloud computing power. There are too many uncertainties and risks.
2. blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
both eurocrowdfunding and Ethereum use blockchain technology.

3. The classic version of bitcoin continues Nakamoto's idea (block development can follow Moore's law), and takes into account the current network situation (especially the firewall where China is absent from work), and increases the original 1m block limit to 2m. Increase the total amount of transactions that the network can support<
the reason for the classic version of bitcoin:
1 the core team (mainly members of blockstream company) insists that the 1m upper limit should not be modified
2 Gavin and others hope to expand the block capacity to increase the transaction volume supported by the network before the block is seriously blocked
3 China mining pool thinks that Gavin's early scheme has too high requirements for the network, Not suitable for the domestic network situation
4 developer Jonathan came to China and carried out a series of field network performance tests for the block size. The test results show that there is no problem for China network to support 2-3m blocks. At the Hong Kong Conference (led by the core team), he shared his test results, but they were ignored
5. Jonathan contacted and interviewed many miners and mine owners, and came to the conclusion that Gavin's original plan was accepted by very few people because of its fast expansion speed, but there were basically no miners and mine owners against the expansion of 2-3m, Developed the classic version of bitcoin
6. The mining pools and companies that were interviewed and inquired by Jonathan began to declare that they support the classic version, because it is the only feasible expansion scheme that can be promoted in the near future, and they have excellent developers.

4. CPU miner, miner must be CPU currency, not enough electricity CPU. Can we use CPU miner to dig bitcoin? It's possible to dig. It's estimated that it will take 100 years to recover
5. First you need to have an okex account and then pass the contract test.
6. Digital currency will affect the index funds of banks, because it has a great influence after all
7. There are two ways to get bitcoin. One is to download software to mine (generated by each P2P computer on the network). However, it is almost impossible to mine by a single computer. At least you need to buy a professional miner. Moreover, personal mining power is too low to compete with the mine pool. 2、 It's buying on the Internet trading platform. Most people buy from the trading platform for speculation. I personally trade bitcoin on the haobtc platform. I buy and sell bitcoin very quickly. I still keep interest on deposit. The interest is not low. There are various ways to manage money, including current and fixed term. They have several large mines. I think they are trustworthy, and they also need to have their own mines. If you have your own mining machine, you can go and dig coins in groups. Don't worry about money digging, trading, trading.
8. The whole process of the coal preparation plant is described as follows:
raw coal from the coal storage yard is evenly fed into the raw coal belt conveyor by the coal feeder, and the raw coal is transported to the screening and crushing workshop by the belt conveyor. In the screening and crushing workshop, the raw coal is screened first through a circular vibrating screen with a mesh size of 50 mm, and the + 50 mm material is picked up by hand for debris and extra large gangue, and then enters the crusher to be crushed to - 50 mm, which is transported to the main plant together with the raw coal under the raw coal grading screen of - 50 mm
raw coal is distributed to two raw coal buffer silos by scraper conveyor in the main plant, and fed into two jigs by two coal feeders. Raw coal is divided into clean coal, medium coal and gangue in jigger. After being dehydrated by bucket elevator, the coal and gangue are respectively transported into the coal gangue bin as final procts by car. The clean coal is classified and dehydrated through a linear screen with 13 mm mesh, and then enters the ling pit for classification with - 13 mm under the screen. The 13-0.5mm fine clean coal in the ling pit is pre dehydrated by the bucket elevator of the ling pit, and then dehydrated by the centrifuge for the second time. The dehydrated fine coal is taken as the final proct together with the screened fine coal, and transported to the clean coal storage yard in front of the main plant by the belt conveyor. The overflow from the ling pit enters the flotation feed tank and is pumped to the pulp preprocessor. The frother and collector are added into the pulp preprocessor, and the coal slurry after dosing flows into the flotation machine- The 0.5mm slime is separated into flotation clean coal and flotation tail coal in the flotation machine. The flotation clean coal automatically flows into the flotation concentrate pool and is pumped to the clean coal filter press for dehydration. The dewatered flotation clean coal is added into the jigging clean coal as the final proct. The flotation tail coal flows into the tailing pool of the concentration workshop, and then is pumped to the thickener. The two thickeners are standby for each other, so as to ensure that the slime water will not be discharged when the thickener has an accident. The underflow of the thickener is dehydrated by the filter press in the main power house, and the slime is transported to the outside of the main power house for sale. The overflow of the thickener and the filtrate of the filter press flow into the circulating pool in the concentration workshop, and then pump to the jig for recycling. Low pressure air for jig is supplied by blower through air bag
the slime of the whole coal preparation plant is recycled in the plant, and the washing water is closed-circuit circulating, and the slime water is not discharged in any case.
