Theoretically, quantum computers could harm bitcoin in particular and cryptocurrencies in general. But the problem is, according to experts, it will take at least 20-30 years for quantum computers to develop powerful enough...

According to Tether CEO Paolo Ardoino, quantum computers are still a long way from being able to break bitcoin's cryptography.

Or according to recent reports, quantum computers need to reach at least 1 million qubits to be able to threaten bitcoin instead of 10-20 million as before. But meanwhile, the most powerful quantum computer today is IBM's Condor, with 1,121 qubits. And as far as I know, quantum computers have been researched and developed since 1980, which means after 27 years, they have only achieved 1,121 qubits. At that rate, how many years do you think it will take to reach 1 million qubits?
My 20-30 year estimate is somewhat conservative, as at the current rate of development, quantum computers may take much longer to get there.
Additionally, Bitcoin uses the SHA-256 algorithm, which is also the algorithm that banks, corporations, and even governments are using to protect confidential information. If quantum computers can threaten bitcoin, traditional systems will suffer the same fate as bitcoin.
