Your thoughts about Quantum Computers, is it a threat?

[genievic23]

I've been reading about quantum computers, it can solve computation faster than any computing computer today, and it can also crack encryption it says, is it a threat for blockchain? and you can't hide anymore? it can be traced back to you so the decentralized thingy will later on be useless?  the cons is the U.S goverment will use it to trace and crack other codes and you can't transact anonimously? Can someone enlighten me please?

I really hope that this coin can grow rapidly, because I see that this coin deserves attention for a long time, after the coin is widely known to the public.
