China is able to do 50%+1% attack. It means, China dominating the crypto's. Or?
Google has quantum supremacy.
What are you thinking?
Who is China? The biggest country? I dont think China have one single miner. But lest say tomorrow China buys tons of ASIC miners. What they will do then? Cheat people out of their Bitcoins. They will buy grain from someone and pay with Bitcoin and then revers transactions back? They will be thefts? That is what you believe China is? A country with 4000 years tradition will now suddenly start stealing peoples money? If Chian want to rob people they can do it without Bitcoin mining farms. They can steal any way they want.
Goggle have, I dont even know, a 40 qubit computer? 40 qubit computer cant break Bitcoin algorithm. You need 267 qubit computer for that. I dont understand why is that so hard to understand for some. It wil take at least 10 years that Bitcoin will be forced to just in case change algo.
