However, while this idea sounds wonderful, it cannot be realized

This will bring great inconvenience to the transaction. The limitation of bitcoin also determines that it can not meet the needs of transaction< br />

currency characteristics
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
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
exclusive ownership: the private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
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
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay

advantages
complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm. Anonymity, tax exemption and supervision free. Robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
cross border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records. It's hard for a cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
disadvantages

Making bitcoin more suitable for speculation rather than anonymous trading. The public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless.
the value of bitcoin:
1. Avoid war, keep value, etc. If a country is in chaos, bitcoin will become the first choice for many people. Although gold is more stable, it is not convenient to carry. If the country is in chaos, who dares to carry a lot of valuables out? But bitcoin is different, as long as you remember the key of the wallet (many wallets are written with mnemonic words), even if you go empty handed, arrive at a safe place to download a wallet, and enter the correct key to take it out
2. It is used in some gray instries. For example, in the year of 17, the global computer virus blackmail event was bitcoin for blackmail
of course, there are others, mainly these.
