Overall, i think we should not panic and do not recommend others to withdraw there funds until they make some announcements because such panic and quick withdrawals will left that exchange no other choice but bankrupt only. I know it's not an acceptable option for the members who have there funds on that exchange but still i think a little patience is necessary.
I do not know how true anything about this is and I do not want to know. I am not trading on Huobi global for now. Another thing is that after warning that people should not leave their coins on exchanges, some will still leave it there. I will advice people like that to withdraw their money immediately. They should always know that if it is not their key it is not their coin. Exchanges are not places to save coins, noncustodial wallet should be used.
