Re: Is bitcoin and altscoins a massive train wreck awaiting to happen?
once quantum based or other high end computing is introduced they will be able to crack the private keys and take all funds.
the real question to ask you is, why did you post this in an altcoin speculation board
and to answer your question no it is not something we need to worry about for ages. because first of all a quantum computer is not something YOU can buy from a computer store or off ebay and do malicious stuff with and cracking the private keys is not as easy as you think it is and a quantum computer is not as efficient as you think it is.
Agreed. Quantum computers are super expensive if the OP didn't know. And there is no Quantum computers than can break into your bitcoin wallet and steal your private keys. Bitcoin technology are so secured that even what you are speculating will not happened in the future.
