The recent excitement about quantum computing potentially cracking encryption keys raised concerns after researchers in Shanghai demonstrated an attack on a 22-bit key using quantum technology.

However, this breakthrough doesn't pose an immediate threat to cryptocurrencies, as current crypto systems use much longer keys (2048-4096-bit encryption), which quantum computers can't yet crack.

Plus, these quantum systems are still not efficient—they run at extremely low temperatures and spend more time fixing their own issues than breaking codes
