BTC small window

1. 1. Using bitcoin mining machine to obtain bitcoin
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security

2.

Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. Bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment

but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over

3. (1) With low service charge, quick cash withdrawal and many currencies, it supports a variety of well-known virtual currency transactions and is convenient to purchase usdt. It can be said that it is the best exchange in China with app and high security
(2) kucoin overseas version (coin win background) has smooth interface operation, and the speed of withdrawing money is not bad, but most of them are junk ICO coins, many names have not been heard of, there are app
(3) China bitcoin overseas version EXX (slow coin withdrawal, kengdai) gambling platform, fixed-point burst futures, it seems that there is a problem with withdrawing money, there is no app
(4) hot coin overseas version, Collude with OK, dozens of junk money a week, no bottom line, many small problems. Support C2C transactions, there are app
(5) okcoin overseas version, this does not say, OK life black, although support C2C transactions, but bottomless line shelf circle coins, flicker leeks, C2C transactions can not be withdrawn, embezzle the user's four decimal digits of assets tens of millions, careful into
(6) BTCC overseas version, support the dollar UnionPay direct charge, but the handling charge is high, it is relatively low-key in China, The experience of transaction interface is very poor
(7) the overseas version of cloud coin has few currencies and many problems, so it's all warriors
(8) at present, coin an is the largest exchange in China, with the most complete currency and many activities. It doesn't card you to withdraw and recharge money. Although there are so many junk money in ICO, it doesn't have as many problems as hotcoin OK. It has apps, needs to translate Q, and mobile clients don't use to translate Q
(9) Yuanbao overseas version has Canadian financial license, legal operation, insufficient depth, small amount of currency, small transaction volume and insufficient UI beautification
(10) in the bitage, the overseas version takes a very long time to review, and it takes you a long time to pick up the coin and issue the coin. The miner's fee used to be a little higher, but now it's just a little higher. 0.5% for recharge, 1% for withdrawal, and the highest withdrawal fee in the whole universe. The garbage made by the K-line chart can't keep up with the ICO coin. At present, this platform can't stand the temptation of interests, and the card is only issued half a day, The trading volume is a little less. At present, I have abandoned this platform
(11) the overseas version of China's bitcoin has just been opened for trading, and C2C trading has a unique qash trading area. There are many small problems, so be careful to enter.

according to the statistics of bitbao, at present, the common minimum trading unit of bitcoin trading platform in China is 0.01btc, so the 0.0001 proposed by the owner is not available for sale< br />

7. At present, the best is NVIDIA's rtx3090, followed by 3080. AMD's 6000 series has not been officially announced. Currently, 30 series n-cards are not available for some reasons. On the other hand, Intel's 10th generation u doesn't support pcie4.0 technology to match 30 series graphics cards, so it's not cost-effective. You have to wait for the 11th generation IU to match. If you don't want to wait, you can also buy 30 series n-cards and AMD's 3700x This kind of Au should be used first

8. If the toll gate BTC on the expressway is closed, will other windows be closed as well? You invented it? It's called etc. Etc port closed does not mean that others are closed. It may be the fault or modification of etc equipment. If other windows of the toll station are closed, it will tell you that the toll station is closed instead of etc. Since it only tells you that etc is closed, it means that other ports can be opened
