Google has quantum supremacy.
It isn't enough to crack the encription of bitcoin network, but maybe enough to mine Bitcoin with more power as other technologies before...
Google achieved quantum supremacy in an artificial problem tailored specially for quantum computers, and that's it. They don't have quantum supremacy in any sort of practical applications, and they are light years away from it. People who have understanding of crypto just yawned at it, because at this moment it doesn't change anything. Google isn't going to release a quantum miner anytime soon.
