Feels like this is an inside scam, this is just my assumption. This is becoming a "phenomenon" while Bitcoin reaching new highs many of the Bitcoin related websites getting hacked, is this normal? I don't think so, These people should know their responsibilities they are holding Bitcoin, a lot of Bitcoin which is not just a simple coin that deserves a poor security. This is really not acceptable.
It's nothing compared to bitfinex hacked last year which cause
BTC120,000 lost in act, and here they are, keep in the business of global exchanges. After some hacked cases, it's weird for a big platform to keep big amount of bitcoin in hot wallet obviously, that's why people consider it as exit scam. They still trace this address and cooperate with law enforcement as well.
Clearly, this is a matter of deep concern and we are working hard to rectify the matter in the coming days. In addition to undertaking our own investigation, the incident has been reported to the relevant authorities and law enforcement and we are co-operating with them as a matter of urgency.
