Anyways.. I googled Bitpie, and while it's not really the most well-known wallet out there, I couldn't find a lot of people having issues with it, so it could be safe to use.
I'm not willing to test it out for myself, so to any guests reading this in the future if this title gets some traction, caveat emptor.
I used Bitpie to claim countless shitforks back in the day. They also had an exchange on there that allowed you to get rid of them. Then out of the blue the exchange was extinguished with an unsignalled update thus leaving me left holding a large dollop of shit.
For that unprofessional move I would not be inclined to entrust them with my money.
