Bitcoin has a time limit

1. According to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to the regulation of digital currency in China, investors have the freedom to participate in digital currency transactions at their own risk
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. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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 amount of bitcoin is very limited and it has a strong scarcity

warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

2. According to the legendary algorithm, bitcoin has an upper limit of 21 million. But you know the algorithm. Although it's very difficult to make adjustments in theory, if you (the legendary top trading institutions with trillions of wealth) really want unlimited, it's a matter of minutes

theoretically, 2100 trillion, or 250.899. In terms of selecting this value, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, the bitcoin value will return to zero like a odometer

but this is only theoretical, just theoretical. Just like the previous IP address regulations, no one expected that V4 would be used up so quickly. Now it is necessary to use V6. This so-called "maximum integer that can be stored in the form of standard integer" may be broken by the technology upgrade one day a year later, followed by the collapse of the whole bitcoin computing.

3. No
24 hours a day.

4. The general idea of "fragmentation" is to change each block in the blockchain network into a sub blockchain, in which several (currently 100) collations (which can be called "check blocks", in order to distinguish them from the concept of blocks in the scenario of fragmentation) packed with transaction data can be accommodated, and these collations finally form a block on the main chain; Because these collations exist as blocks as a whole, their data must be packaged and generated by a specific miner, which is essentially the same as the blocks in the existing protocol, so there is no need to add additional network confirmation. In this way, the trading capacity of each block will be expanded about 100 times; And this kind of design is also concive to future expansion. At present, the whole expansion plan is roughly divided into four stages; This article only introces the implementation details of the first phase. Transferred from Jianshu. Currency exchange of digital currency

5. Online banking of Bank of communications has the function of settlement and sale of foreign exchange, but it must open the registered version of online banking, SMS version / certificate version. It can exchange RMB and foreign currency in financial management, but it is not real-time. There will be an approval process, but it will be very fast.

6. First of all, how much bitcoin can be exchanged for cash depends on the rules of that platform, that is, how many transactions you can limit.

7. The time of each transaction is 15 minutes. If it exceeds 15 minutes, it will be cancelled automatically.

I believe you all know something about bitcoin. Its existence has caused agitation, especially in the United States, which is often mentioned. But what is its magic power? Its existence is not small. Although it is a kind of digital currency, it brings convenience to people. It allows people to have magic power on it and store it for a long time. Because of its wide use, people have caused a boom. So what is the reason? And, it's so magical and easy to use, will someone hold it all the time? For me, this can not give a positive answer, but we can judge it according to its present and past to see if there is an answer that can be found

But it also has certain risks. Although it seems to have a high degree of anti risk ability to avoid the interference of stock market shocks and M2 inflation, people who think so often fail to clearly realize that digital currency itself is a completely different field from previous financial procts. Although it is not affected by the traditional financial risks, it is also faced with new risks unique to the digital economy. Everything is good and bad, but it can advance your research interest
