I've been out of the crypto game for a few years now and I'm just now kind of dipping my toes into the water again. Admittedly, I was a little angry when my original account on here got hijacked a few years ago and I wasn't able to get it back.
If you don't mind, would you like to share with the community some details about the hacked account? Maybe there could be some help on how to recover it for you.
With the details you provide, probably a wallet linked to the account or any other thing that could prove that you really own the account could give you a chance of getting it back, or you don't want the old account again?

How to recover hacked account I agree, and by sharing it, it could also help other people to avoid it so no one will be ever a victim again of what happened to OP.
I'm glad that even what happened to OP he/she still trust the Bitcoin and not blaming the Bitcoin itself of what happened, it is already a lesson learned for OP.
