Quantum computing is very close. Most conservative estimates say by the end of this decade, easy.
Most modern security is based around very good cryptographic science, but for a supercomputer, even complex passwords could be cracked in less than a day. For ciphers under AES128, most modern, somewhat common, security configurations are based on crypto from 2012.
If quantum computing is achieved near term, those systems could be breached in days if not hours. This is to jumpstart government spending on IT cyber services. It works very well under the Dems.
Quantum computers are a million times too small to hack bitcoin
Bitcoin is theoretically vulnerable to being cracked by quantum computers, but calculations show they would need to be a million times larger than those that exist today
