BT currency is a kind of virtual currency proposed by a Japanese in 2008 and officially issued in 2009
BT coin is like a gold mountain with a total amount of 21 million gold coins (the upper limit of the total amount is designed to be 21 million). To get it, players need to use the computing power of the computer to calculate a group of numbers according to the designer's algorithm, just like everyone working together or calculating a mathematical problem separately, each group of numbers can be obtained, Then you will get a BT coin, and the world can only proce 25 at most every 10 minutes. This calculation process is vividly called mining
of course, these mathematical problems are becoming more and more difficult. From 2009 to now, the output of BT coins is about 10.4 million. The more the quantity on hand, the more difficult the output will be. Bitcoin is scarce. The upper limit of issuance (21 million) has been set. The difficulty of obtaining bitcoin increases geometrically. It is estimated that it will take hundreds of years to complete
it's ridiculous to say that it's an international QB. It's all virtual currencies, but the security and versatility of BT currency are incomparable to QB. TX is closed, QB is finished. But if BT currency is to collapse, it will not be possible unless there is a global power outage or the global Internet is paralyzed
with regard to the use of BT currency, the world has begun to accept the use of BT currency. Germany first recognized the legality of BT currency, and China also has a trading website BTChina, which can directly exchange BT currency into various current currencies of most countries, including RMB. In China, there are many sellers who accept BT coin on Taobao, and there are also many stores and supermarkets that begin to accept BT coin in Beijing, Shanghai and other large and medium-sized cities
just now, the BTC / RMB exchange rate in this second is 1 / 4888.03, which is still very valuable, but mining needs a lot of investment in advance. A professional mining machine (professional configuration for BT coin computer) is about 40000, 60 such machines work 24 hours, the output can be about 50. In addition to the astonishing power consumption and custody costs, the cost will be recovered in about a month. If you want to make money by mining your ordinary computer, it's a fable. If the owner has no capital investment, it is suggested to give up. The standard configuration of 5000 computers on the market, 48 hours of work also only dig out 0.001 BT coin... Thanks to grandma's house, the main reason is that there is capital investment in the building, so we have to hurry up. At present, it is estimated that the proction and income can still be profitable for 3 or 4 years at most. After this time, mining will not be able to make ends meet.
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it
bitcoin is a kind of P2P digital currency
bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions
the biggest difference between bitcoin and other virtual currencies is that the total number of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
this virtual currency only needs the computing power of the computer, and it has no technical content. Basically, it only needs to hang up to "generate" bitcoin, and bitcoin can be traded at any time, so as to transform it into real currency
if you want to get bitcoin, you need to download the special "mining software" and set it to start
In general, the computing power of GPU is much higher than that of CPU, and even the entry-level graphics card is much better than the top i7 series. So it indirectly tests the performance of the graphics cardMining index is to test how long it takes for a computer graphics card to dig out bitcoin or lettercoin. Because it was popular to dig all kinds of money to earn commission, the corresponding software also added mining index evaluation function, such as Master Lu
Open Master Lu and click the mining index on the right to pop up the middle interface as shown in the figure. Of course, the graphics card does not support it. If the graphics card supports it, click the "one click test" below, and the mining index of the computer will be evaluated after a period of time
February 24 (Xinhua) the security of encrypted digital currency assets is completely based on the security of the private key of encrypted digital wallet, which is the only digital asset certificate. Once the private key is created, it cannot be modified and reset. As long as the private key is not lost, the asset will not be lost. Therefore, the whole security topic of encrypted digital assets is around the storage and use of private key. For the light wallet mode used in mobile terminal wallet, the security of user terminal private key storage is a very core and key problem. If the design is improper, it may lead to the loss of private key and the theft of assets
Jaxx is another well-known mobile cryptocurrency wallet, which has a large number of functions, including supporting multiple currency types, as well as the recently added digital currency exchange platform, allowing users to exchange bitcoin, Ethernet and erc20 tokens in the wallet
when we check the data backup mechanism of Jaxx, we find a major security vulnerability, which is more serious than bitcoin wallet. In fact, the private key stored in Jaxx can be stolen by hackers with little effort
In my opinion, Musk's selling of bitcoin is more of a means of selling high and absorbing low. It can realize the accumulation of basic capital by selling high and absorbing low. Musk bought a lot at a low price, and then because of his own identity and Tesla's company, it once led to a substantial growth of bitcoin, but after it rose to a certain extent, Musk's selling of bitcoin was not successful, Its upward trend has eased, or it is in a state of decline at present, so if musk considers it from the perspective of capital, now is also a good opportunity for operation
coupled with a series of Musk's propaganda, for example, Tesla once announced that bitcoin can buy Tesla cars. In this way, bitcoin has become a kind of existence next only to currency. Bitcoin itself is recognized by governments of all countries. After all, recognition of bitcoin means impact and influence on domestic currency, But as a leading enterprise, Tesla's announcement is a good news for bitcoin, which stimulates the rise of bitcoin price. Therefore, Musk's selling of bitcoin this time is mainly to harvest retail investors, because no matter in the stock market or bitcoin market, one of the principles followed is zero sum game. There are winners, there are losers, there are losers, there are winners, the total amount is so large
