just had almost $1,000 stolen by someone who hacked my account on this site
almost means your balance is not yet been haced right? So I think your balance is still safe and that would be no problem here. But the only thing is why you can be hacked? Do you ot put any protection like 2FA? Because when you put this on, there is no possible hacker wil be able to hack your account
Put 2fa is still possible to be hacked especially if the hacker is his own close friends/families who can borrow his PC/phone where he install the authenticator or his PC/phone was stolen.
But not really sure about this case, probably yes he did not put 2fa and he clicked on suspicious link that steal his credentials.
There are tons of people who are not tech savy. They wouldn't even know how to protect themselves properly. Besides this is quite unbelievable especially it came from a new account
