Though Metawin is financially stable but still it is concerning for their security system. I don't know either they will get the previous place to the players or players will confuse about using Metawin. Hope they will be able to gain the previous trust of the players.
They were able to restore withdrawal without much delay for their customers, which I see as what customers don't like being denied access to their funds.
Second, as long as customers funds were not affected, I don't see any reason for the players not to trust them. The only thing is that after they have covered up the mistake that led to that hacking, they should also try to improve in security to avoid such from happening in the future; they can't keep losing money to hackers.
