Bitcoin disappeared

This situation must be timely feedback to customer service, to retrieve

if bitcoin is stored in the account of the exchange, all the coins are in the big account of the exchange. If the exchange stops trading or goes bankrupt, all the coins belong to the actual controller of the exchange (the person who has the key of the big account)

therefore, if there are official problems in the exchange, we must contact the official customer service in time to retrieve them. In addition, digital assets, blockchain and other technologies will have unpredictable effects, and problems in the development process need to be standardized

extended information:

people who really own bitcoin do not store them on the Internet, but store them on the hard disk. Bitcoin's code is open source, which means that technicians can modify the code to proce a continuous stream of virtual currency

which breaks through the "limited amount" attribute of bitcoin. These virtual currencies can be exchanged with fiat currencies. For example, bitcoin can be exchanged into yen, and yen can be exchanged with almost all fiat currencies in the world

in this case, if the number of virtual currencies increases arbitrarily, there will be problems in the whole international monetary system. Therefore, on September 4, 2017, the central bank stopped the exchange function of the token trading platform, especially the exchange function with legal tender

According to Chaina alysis, a research firm, up to 20% of the existing bitcoin has disappeared forever. At the time of the study, about 3.8 million bitcoins could never be retrieved. In this article, we will explore all possible ways to lose bitcoin

1. Cryptocurrency hackers

the hacker behavior of cryptocurrency exchange is the main reason for the loss of bitcoin. Exchanges are a hot target for cyber criminals, accounting for 27% of cyber attacks in 2018. Mt. GOx was the first high-profile cryptocurrency hacker, but since then, many major exchanges have been hacked, including bitfinex, bitstamp and, more recently, cryptopia, the cryptocurrency exchange in New Zealand, which lost 9.4% of its total positions

the malware on torrent website and Google play store are used to steal passwords from vulnerable categories. For example, there is a malware clipper that uses users' behavior of ing and pasting wallet addresses to steal passwords. For example, if you send BTC to an address, you usually and paste the address, because it is a long string of random characters, clipper malware will exchange wallet addresses, which means that when you paste, you will send encryption to the wrong address

Where is Nakamoto? In my opinion, Nakamoto may never exist maybe he's just a code, or maybe he's just a name invented by a bitcoin team. Over the years, the outside world has been speculating about the identity of Nakamoto, but no one has ever seen him as a real person{ RRRRR}
