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?
The process of creating a quantum computer will certainly take a very long time, it will probably take around a decade, considering the long launch time so I think their crypto developers will definitely continue to develop and improve security because they are also anticipating the presence of quantum super computers.
