Let me avoid the technical aspects to make things easy for all readers.
So someone said that America's NSA has this great computer(quantum computer) that could easily hack Bitcoin private keys. I really doubt his claim but I know for sure that certain computers like the most powerful Super Computers are within the reach of some of this Intelligence organizations.
Do you think such computers can crack any security codes put in place to make Bitcoin very secure?
Maybe yes maybe not because hard to conclude and under estimate the capabity of new technology inckude the capability of the genius are can't forgive .
But i still believe in the group of cryptocurrency enthusiasm continue also to improve the security system of bitcoin to avoid hack the system.
