Hatu, my dear friend, do you think the quantum computers of future will not decipher the passwords of the current bank systems? Bill Gates had said when Internet emerged for the first time, this is crap and will certainly fail, but he was wrong, since the technology will be used to improve security techniques, every problem will be eliminated in parallel to the development of crypto currencies.. At least you can see easily that many institutions are adopting bitcoin as a payment method. It means storage risks are taken intrinsically, it means development even if some people do not get it easily..
RE: Your Bitcoin, ETH, STEEM, and other Crypto are NOT stored securely.
