First: My condolences on losing your account. That must have been incredibly frustrating seeing all the hard work gone. Watching your HP stake being taken week after week until it vanished :(

I think you got the account name long as : @tahirazaman seems to be the account that has everything being drained from it (I took a look).

Personally? I recommend keeping a portion of investments on HIVE and a portion off HIVE and rebalance regularly. HIVE is great but as you found out it only takes one issue with keys and you are finished. Also HIVE can go up and down very quickly.

Good luck rebuilding.
