Tokyo bitcoin exchange stolen
Mt. gox2, the operator of the world's largest bitcoin exchange, announced on 28 February that it had applied to Tokyo District Court for bankruptcy protection because 850000 bitcoins on the trading platform had been stolen
I have always trusted btc123. In 2013, I first found the fxbtc mainland platform on btc123 to buy bitcoin, and fxbtc collapsed and lost a lot of bitcoin. At that time, I thought that the mainland platform was not very reliable. Then I found mycoin on btc123, the Hong Kong platform. Considering that the legal system in Hong Kong is more perfect and btc123 is an endorsement, it should be safer. So I bought 2 million bitcoin from huocoin.com and transferred it to the multi currency treasure in mycoin platform for storage!!! Often login multi currency account, has been able to log in, and every day there is interest payment. In February of 2015, I happened to see the news that the boss of the platform ran the road and Hong Kong's capital took 3 billion yuan away!!! Then the mainland economic investigation called the police and refused to accept it. It said that the office address was in Hong Kong and asked me to call Hong Kong to report to the police. The Hong Kong police station received a call saying that I should report to the police in the mainland, and bitcoin did not accept the call to report to the police. Finally, it said that I could report to the police online first. I called the police on the Internet, no news!!! Now call the day should not, call the ground not work!!!! I hope the media, the government or the police can help me. I can't say that I have no hard-earned money for 15 years! I wonder if we can sue btc123 together? What else can we do to rece the loss? Thank you

GOx was attacked by large-scale hackers one month before its bankruptcy. Most of its bitcoins were stolen by hackers, with a total value of $470 million

On February 28, 2014, the Tokyo bitcoin exchange, MT GOx, filed for bankruptcy, claiming to have lost about 850000 bitcoins. Recently, an investigation report from wizsec, a bitcoin security company in Tokyo, shows that the bitcoin lost by MT GOx was graally stolen from the exchange since 2011. The bitcoin was stolen long before the bankruptcy of MT GOx. After that, MT GOx continued to operate through a part of bitcoin reserves. Whether MT GOx itself knew about the loss of bitcoin at that time has not been found out
the stolen bitcoin was sold to many exchanges including MT GOx. According to the time, the selling price of these bitcoins should be much lower than the highest price of bitcoin in 2013 and 2014
According to several okex and okcoin users, their accounts were stolen, with losses ranging from tens of thousands to millions. According to preliminary statistics, nearly 10 users have reported losing about 600 bitcoins, worth about 20 million yuan
On September 1, some users said that they had 468 okcoin accounts, only 125 of them were left, 343 less. The user said that there is no need for any password or verification to transfer the okcoin contract account to the spot account. The developed currency to currency transaction has no depth at all and is easy to be used by the number stealing personnel. Okcoin does not provide corresponding protectionon September 16, another user transferred 30 BCC tokens stored in okex to okcoin, and on September 23, the account was invaded again, buying and selling between bitcoin, Leyte, Ethereum and RMB for many times, exhausting 30 BCCs and 27 bitcoins, trading nearly 1000 pieces in two hours, and the abnormal IP addresses were Russia and the Netherlands
"if the virtual currency property is changed into legal currency for cash withdrawal, the account is required to have real name authentication, so it is necessary to withdraw the profit in one stroke by knocking or exploding the position." Liu Chaoqun thinks that several problems of okex platform include: there is basically no trading volume of currency trading at ordinary times, and the trading volume suddenly increases a hundred times, so the platform does not do any risk control on this; There is no email or SMS verification for remote login; After the remote login reminder, immediately contact the platform, and the platform does not respond at the first time; The withdrawal speed of profit account is obviously abnormal, much higher than the normal speed
