No, of course not, that is the most shitty wallet/exchange that exist, they have been acting with bitcoin cash and roger ver together in order to make bitcoin go down.
Avoid this wallet, and the exchange, they are only manipulators.
I'm by no means defending them but they're definitely not the worst. The thing people need to understand is they got hit by a MASSIVE wave of new investors in a short amount of time and their systems have had trouble handling it all. As far as customer service goes they most likely don't have enough employees to handle all of the incoming support requests, again because of the massive number of new accounts.
At the same time though they certainly could have anticipated these things and did a poor job planning for them.
The insider trading thing is definitely sketchy too.
