Why Japan's virtual currency was 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
