If Google starts designing these computers in mass, then it could result in a risky journey for Bitcoin within days ahead.
There is nothing yet for Google to produce - currently it's a prototype, insanely expensive and complicated.
Will be a few years yet before these are available for private use. But yes, quantum computers are a danger not only to crypto but all banking and anything else that uses encryption.
Deserves a merit because pretty much on point. They are years away from public use and even if there is a hint of trouble due to private use in Google labs then it's not only bitcoin which would need to increase their security it's also most websites and especially banks.
Right now I wouldn't worry and this was discussed last week when we got the crash all the way down to $7200. People were saying that Bitcoin is crashing because of Googles quantum computer and its not longer secure and hence the sell-off. It was nothing but a coincidence and we rallied about $2000 since then so obviously nobody who is buying Bitcoin thinks it's an issue.
