When choosing a wallet, the owner must keep in mind who is supposed to have access to a copy of the private keys and thus potentially has signing capabilities. In case of cryptocurrency the user needs to trust the provider to keep the cryptocurrency safe, just like with a bank. Trust was misplaced in the case of the Mt.
