Is Bitcoin valuable? The formula for Bitcoin's value is revealed. Of course Bitcoin is valuable. Today's price is more than 55,838 per coin, and the highest has risen to 120,000 per coin. There are two kinds of views on Bitcoin at present. One is that Bitcoin is a bubble and will eventually return to zero. This kind of people tend to believe that Bitcoin has no practical application value. Another is Bitcoin believers or investors, because Bitcoin has skyrocketed 9 million times in nine years, allowing many people to overtake others and become wealthy overnight, such as Li Xiaolai of New Oriental in China. They believe that Bitcoin will continue to soar.

Formula for Bitcoin's value - Rleq min (A, C, kN) A is the value of the system, C is the upper limit of the safe transaction volume, and kN is the transaction volume.
For Bitcoin, the first two will increase with the number of users N.
That is to say, compared with the general transaction system, the value of Bitcoin will not be restricted by A and C, that is, it seems that if the number of users can grow indefinitely, the value of Bitcoin will also grow indefinitely.

However, the transaction volume of Bitcoin, that is, C, is actually capped, which is the famous 7 transactions per second.

Many people who have only a limited understanding of Bitcoin technology say that this upper limit is only subject to Bitcoin's rules, and that there is no technical difficulty in expanding the capacity, and that a block of 100MB is not a problem. BTC (miners) are unwilling to do so only because of ulterior motives, and so on. They are all half-baked people who do not understand technology.

This upper limit is due to the 1MB block size and 10-minute block frequency. It is true, but in the final analysis, it is subject to the security of proof of work, which requires weak synchronization of the entire network, and in that case, the block size cannot be too large.
So, this upper limit is ultimately subject to the network speed and computer response speed, as well as the number of nodes. Even if the expansion increases the block size, it is impossible to increase the block size to 100MB.

At present, segwit2x and bcc have increased the block size to about 8MB, which is basically the limit that Bitcoin can reach at present. In other words, the transaction volume will increase by about 8 times.

But the network speed will increase - think back to the network speed 10 years ago, and look at it now, the increase in network speed is about 100-1000 times. However, the past decade has been a decade of rapid development of communication technology, and it has now reached a bottleneck period.

The most optimistic estimate is that the network speed will increase 100 times in the next ten years. Therefore, if the capacity is expanded at that time, a block can be about 800MB (one block every ten minutes).
So, from this perspective, in ten years, Bitcoin will theoretically rise to a maximum of 3.2 million US dollars per coin, and one coin can buy a luxury house in Beijing, Shanghai and Guangzhou.

You said that a coin could be worth $3.2 million, who wouldn't flock to it? Marx wrote: "If there is a 10% profit, capital will be guaranteed to be used everywhere; if there is a 20% profit, capital will be active; if there is a 50% profit, capital will take risks; for 100% profit, capital will dare to trample on all human laws; if there is a profit of more than 300%, capital will dare to commit any crime. At present, you don't have to break the law. As long as you can use mining machines to mine coins, you can get huge profits. All those who have the conditions will try their best.

Bitcoin is still valuable for the current market. Although most countries and governments still do not recognize its currency value, there are already many related trading platforms on the Internet. As of March 6, 2018, one bitcoin can be exchanged for about 75,000 yuan. As for why so many people mine Bitcoin, the first point must be the money effect. For a virtual currency, it has risen nearly N times in ten years, and The market is constantly hyped. There are rumors that the future value of Bitcoin can rise to about $100,000. Coupled with the hype of decentralizing virtual currencies, many people are constantly entering the virtual currency industry.

Bitcoin does not rely on a specific monetary institution to issue it. It is generated through a large amount of calculations based on a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transactions, and uses cryptographic design to ensure the security of all aspects of currency circulation. The currency system has no more than 10.5 million in 4 years, and the total number will be permanently limited to 21 million afterwards.

Bitcoin is a type of blockchain. Blockchain is a global distributed ledger. The special accounting method makes it difficult for blockchains to be hacked, which also makes it impossible to check the transactions of Bitcoin developed from it. This encrypted transaction is very popular, especially black and illegal transactions, which is one of the reasons why Bitcoin is so valuable.
