50 bitcoin proxy
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million
extended data
monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
Based on these two situations, price fluctuation seems to occur within 18 months after each halving. However, the data is still insufficient for proper analysis and price forecasting model
Will history repeat itself< p> It is important to note that in terms of the number of bitcoin holders, market value, regulations and the overall outlook for cryptocurrency, there are huge differences between 2012, 2016 and 2020. For example:market value: November 2016 - & gt; $11 billion, December 2019 - $132 billion
daily trading volume: November 2016 - & gt; 84 million US dollars, December 2019 - 17 billion US dollars
e to the increased public awareness of bitcoin and the interest of institutional investors, the risk is higher this time. Although many other cryptocurrencies have been introced since 2016, BTC's dominant position is still 66.6%. As a result, the bitcoin miner is unlikely to switch to other coins, which means that halving may have a long-term impact on bitcoin prices
However, the main gain is that there is a certain correlation between the halving of bitcoin reward and the price fluctuation after the event. These supply changes happen every four years, and it's interesting to watch their impact on the price of the bitcoinBT 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.
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.
Huili is the earliest fashion brand of rubber soled shoes in China. In the 1970s, Huili shoes were almost the only symbol of sports and leisure shoes; Compared with Jiefang shoes, its concise and distinctive design is outstanding in that era of homogenization. By the 1980s, owning a pair of kickback shoes was already quite a trendy symbol among teenagers. After the reform and opening up, a large number of sports shoes brands have entered the Chinese market. Although Huili is still well-known, it is no longer the first local brand. People's impression of Huili shoes is associated with migrant workers, because it is cheap and rable, rather than a high-end brand
maintenance and cleaning of Huili shoes:
1. Most canvas materials of Huili shoes need to be coated with a layer of paste before leaving the factory e to the proction process. In order to make the vamp more upright, it is better not to use washing powder when washing, but to use soap. When washing shoes for the first time, try to wash off this layer of slurry, and wash the soap thoroughly with water after washing, otherwise the vamp is easy to turn yellow
2. Washing shoes is suitable for cold water cleaning. Of course, some serious stains may still need to be washed with warm water. But never use overheated water, otherwise the rubber is easy to open
3. Serious stains can be cleaned with 84 disinfectant. 84 disinfectant can not only be used for sterilization in SARS, because 84 has a great corrosive property, which makes the legs of clothes color, so 84 can be used to remove sweat stains. When cleaning serious stains, you don't need to dilute 84, you can directly drop 84 original liquid on the stains, let 84 stay on the vamp for about 10 seconds, and then you can brush with a toothbrush. Finally, clean 84 thoroughly with water. If not thoroughly, 84 will corrode the upper
4. After washing shoes, wrap the vamp and rubber parts with straw paper and dry them in the shade. Remember not to be directly exposed to the sun. The rubber of shoes is easy to age and open, and the vamp is easy to turn yellow. Especially the white vamp, a yellow finish
5. Wrapping the vamp with paper towel is also OK, mainly to prevent the shoes from being directly exposed to the sun. It's best to use straw paper, the worse the better, because the poor straw paper contains a lot of fluorescent agents, so on the one hand, the vamp will turn white when wrapping the shoes.
