I have just studied the history of huobi. When the exchange opened in 2013, a large number of investors invested in it.
One of the cool things the company has done is that it has kept 2,000 bitcoins for days if they were hacked, which is a great feature because a lot of platforms and exchanges if they are hacked, because They have no financial backing, they can not return the users money, and even if they do in the end, it takes a long time.
