How much of BTC has not been dug up

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. The biggest difference between bitcoin and other virtual currencies is that the total number of bitcoin is very limited and extremely scarce. The total number of bitcoin is about 21 million. At present, 17 million bitcoins have been mined

1 First of all, register Singapore foundation as the main body of the project:

Singapore, with its highly open attitude and loose policies, encourages the booming of the blockchain instry in Singapore. Compared with the domestic and Asian countries that explicitly prohibit ICO, Singapore, with its advantageous geographical location and the communication of Chinese language and culture, as an international financial center, is the best choice for you to do ICO

let's briefly talk about Singapore's policy of opening up to virtual currency: what are the advantages of choosing Singapore foundation as ICO

First of all, Singapore has always been in a friendly attitude towards blockchain projects

Secondly, as far as the current Singapore market is concerned, most of the world's well-known blockchain projects are located in Singapore, which is already a relatively mature and well-known market. Some well-known blockchain platforms such as lightcoin, Biyuan and Weilian have been established in Singapore foundation to issue ICO projects

3. After the registration of Singapore foundation, the local licensed lawyers in Singapore can issue relevant legal compliance opinions

how to register Singapore foundation

registration information of Singapore Foundation:

1. Company Name: end with limited / Ltd, and add foundation in the middle

2. Director information: 18 years old or above, no criminal record, at least 2 directors, one of whom is Singaporean or long-term resident in Singapore, and the other has no restrictions on nationality. Provide the registered person's ID card or passport (scanned )

Registered capital: default to S $1

Registered address: local address in Singapore

Business scope: software development (consulting), information technology services, it research, etc

registration time: acra's official registration time for non-profit public foundations is 10-25 working days, and the general registration time is about 20 working days

based on the domestic policies of blockchain and ICO projects, choosing to invest in Singapore's blockchain can not only comply with the registration of Singapore foundation company, but also provide legal opinions by Singapore lawyers, which is concive to the legal compliance of blockchain practitioners to issue currency on the exchange. Therefore, it has become the consensus of the instry to invest in Singapore's blockchain, So it's a good choice to set up a foundation in Singapore to be an ICO

Virtual currency seems to make people rich overnight, such as bitcoin. At the beginning of the year, it cost a few yuan, but now it costs US $50000. Not all virtual currencies are bitcoin. It's better to be cautious. Now many friends want to invest in the digital currency of the blockchain and join the army of overnight wealth Red wine and other goods are given away by the company; Dark blue integral;, At the same time, points also have consumption value-added, which is returned in the form of points. Points can also be converted into virtual currency of the trading platform, namely & lt; Beilan coin;, Virtual currency can be traded or withdrawn on the trading platform, and it can rise or fall

shortly after the company's operation, it invited another nickname & quot; Fengshen & quot; Network operator, joint operation & lt; Dark blue integral & quot& ldquo; Beilan Coin & quot; Network platform fund-raising project, behind the beautiful gimmick, is a fraud of illegal fund-raising

in order to attract victims into the trap, put on appearances, buy luxury cars, expand false publicity and attract investors

later, e to the conflict between shareholders, the operator was reported and arrested by the public security organ, the company project finally collapsed, and this illegal fund-raising case graally surfaced

4. The bitcoin system adjusts the difficulty coefficient to ensure that bitcoin will not be g up too quickly
every 10 minutes, the miners of the whole network work together to solve a problem and compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will soon be g out
in order to ensure the stability of bitcoin and dig out a block in about 10 minutes, Nakamoto Tsung designed that the difficulty of getting bitcoin from miners' mining should be dynamically adjusted every 2016 blocks (about 2 weeks). After the adjustment, the expected time for each block to be generated is 10 minutes
the current difficulty coefficient is about 480ph / s, which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer and generate a new block.

5. According to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, it is an ideal state that the "proction time of each block is 10 minutes" used in the above calculation method, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error.

6. The total number of bitcoins is 21 million. At present, 15.85 million have been g out, so the output has become less, and the interest rate of the major proposed platforms has been reced accordingly. If you pay attention, you may have noticed that the centrifugation of haobtc and the major platforms has been adjusted. You can pay attention to the dynamics of the next currency circle when you have nothing to do. It will help you.

7. So far, there are 11579500 (at this moment)
there are 9420500 left
adopt me

next, it's good to go to GBL, so I mainly play GBL

8. It doesn't matter how much bitcoin is. The smallest unit of bitcoin can be one in a billion. So don't worry about quantity.

9. Bitcoin is more and more difficult to dig in the future. Now ordinary computers can't dig a coin a year, so it's very difficult to dig out. In fact, it doesn't matter how much bitcoin has not been g. The minimum unit of bitcoin can be one in 100 million, so there's no need to worry about the quantity.

10. At present, if it is an ordinary desktop, it will take about 30 years to dig out one
