Every bear market cycle involves hype around quantum computers, claiming that $BTC will go to zero.

Some people worry that Google's quantum technology might threaten Bitcoin. Let me put it this way: if quantum computing could crack the elliptic curve encryption behind Bitcoin, the world would have already been turned upside down. The entire encryption industry is worth less than three trillion dollars, and Bitcoin wouldn't even make the list. $BTC $ETH
Banking systems would be directly rendered obsolete.
Interbank transactions, credit card payments—these systems maintained by modern encryption technology—would become completely useless. Attackers could easily forge data and transfer funds, making banks essentially give away money for free.
Encryption in the financial system
The encryption technologies used in finance, like RSA+, ECC+, are even more fragile than blockchain. If they were cracked by quantum computers, the global financial system would be as fragile as paper, and assets could vanish instantly.
All communication would be exposed
HTTPS, SSL, VX, emails, banking websites—all online communications would become insecure. Who you chat with, what you buy, how much you earn—all could be live-streamed.
National secrets would become a joke
Even nuclear missile encryption codes wouldn't hold up; nuclear weapon passwords could be easily cracked. Just think about how terrifying that is.
If Google's quantum computing truly reaches this level, you shouldn't worry about Bitcoin becoming worthless. Instead, you should be concerned that the fundamental logic of the entire world will be redefined, and the rules will be completely replaced with a new set.
Most likely, the first thing each country would do is eliminate Google and arrest all its top executives.
