The world of technology is evolving every year what if in future a new tech is been born that can kill crypto or works better than crypto won't this kill cryptocurrencies?
Also I heard that super computers can get through all crypto wallet keys easily in a matter of days, true or false?
I believe there could be a possible way of decryption to any encrypted data. But in the mean time while we wait for the advent of such super computers we can still enjoy the little security guaranteed by the current Blockchain technology at hand but if by chance the crypto get replaced by another advanced technology it would not be completely wiped off rather there would be a correlation between both technologies
