Cryptocurrency needs proper identity verification
It's the most common thing needed it's the main reason that is stopping CRYPTO to enter real world.
Probably that will be the best thing that are needed in cryptocurrency which is the proper identity and can be additional to this is to have a much suite and much better regulations therefore it cannot easily using by some worst people in their illegal transactions. As we known that there are a lot of news that regards to crypto involvement that's why some other peoplpe are afraid or hesitate to have an involvement in crypto world and maybe the reason why some government are really banned it in their respective countries.
I don't think the proper identity needed to use crypto currencies then what is the use of decentralized it is almost like old and more worse than the fiat money system.So we don't need identity if we have then people may think that then what is the difference between currency and new and why we need to move to a new system.But governments are really scared of economical crisis not the terrorist activities that is the reason they are banning crypto currencies.
