Quantum computers, some people think that they would be a risk to bitcoin... However, there is something called quantum resistant address is. There is already technology in the works to prevent quantum computers from being able to affect Bitcoin. Cryptocurrency is here to stay whether the haters like it or not.
True, and blockchain technology, DLT or any systems can even use this quantum technology for their own advantages. Fast transaction,added or high security etc. Bitcoin can really utilize this technology for a better services. I think theirs nothing to fear, let the technocrats, scientists do their job in finding innovation and solution.
