On May 20 12 17, the global sudden bitcoin virus attacked public and commercial systems crazily!

Monetary characteristics
Decentralization: Bitcoin is the first distributed virtual currency, and the whole network consists of users without a central bank. Decentralization is the guarantee of bitcoin security and freedom.
Global circulation: Bitcoin can be managed on any networked computer. No matter where you are, anyone can mine, buy, sell or collect bitcoin.
Exclusive ownership: manipulating bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the users themselves.
Low transaction cost: Bitcoin can be remitted for free, but in the end, a transaction fee of about 1 bit will be charged for each transaction to ensure the faster execution of the transaction.
No hidden cost: Bitcoin, as a means of payment from A to B, has no complicated quota and procedures. You can pay by knowing the other party's bitcoin address.
Cross-platform mining: Users can explore the computing power of different hardware on many platforms.
superiority
Completely decentralized, without issuers, it is impossible to manipulate the number of issues. Its distribution and circulation are realized by open source p2p algorithm. Anonymous, tax-free and supervision-free. Robustness Bitcoin relies entirely on p2p network, and there is no distribution center, so it cannot be closed to the outside world. Bitcoin prices may fluctuate and collapse, and many governments may declare it illegal, but Bitcoin and its huge p2p network will not disappear.
Borderless, cross-border Cross-border remittances will go through layers of foreign exchange control institutions, and transaction records will be recorded by many parties. But if you use bitcoin to trade, you can directly enter the digital address, click the mouse and wait for the p2p network to confirm the transaction, and a lot of money will pass. Without going through any regulatory agencies, no cross-border transaction records will be left. It is difficult for people in shanzhai to survive. Since the Bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile and create a new p2p currency. However, these counterfeit coins are very fragile and vulnerable to 5 1% attacks. Any individual or organization, as long as it controls the computing power of 5 1% of a p2p coin network, can manipulate the transaction and currency value at will, causing a devastating blow to p2p coins. A lot of counterfeit money died in this link. The bitcoin network is robust enough, and the number of cpu/gpu needed to control the computing power of 5 1% of the bitcoin network will be astronomical.
disadvantaged
Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. The trading platform is generally a website, which will be attacked by hackers or shut down by the competent authorities. The transaction confirmation time is long. When the Bitcoin wallet was first installed, it would take a lot of time to download historical transaction data blocks. When trading bitcoin, in order to confirm the accuracy of the data, it takes a certain amount of time to interact with the p2p network, and the transaction is completed after the confirmation of the whole network.
The price fluctuates greatly. Due to the involvement of a large number of speculators, the price of bitcoin for cash has fluctuated like a roller coaster. Make Bitcoin more suitable for speculation rather than anonymous trading. The public does not understand the principle and the resistance of traditional financial practitioners. Active netizens understand the principle of p2p network and know that Bitcoin cannot be manipulated and controlled artificially. But the public doesn't understand that many people can't even tell the difference between Bitcoin and Q coins. "No issuer" is the advantage of Bitcoin, but in the eyes of traditional financial practitioners, the currency without issuer is worthless.
