I had bitcoin stolen by a hacker 1 month ago, I have since set up a stronger PW and 2FA. Also gonna accumulate BTC on a paper wallet. Is it safe to reuse the hacked account to trade? If not, what are the options?
That would depend on how your account got hacked in the first place.
If he
1. bruteforced your account password, then yes, it should probably be fine.
2. used a database (
https://leakedsource.ru/) for example, to find out the password of your email / exchange, you should probably still be wary.
3. used social engineering ( although i'm not too sure this is possible with most exchanges), it wouldn't really be safe to use the same account again, as i'd say that the chances of it happening again are pretty big.
I myself would've probably created a new account with a clean email, but you'll need to make your own decision.
