...I also agreed with your opinion that cryptocurrencies can be more developed, because internet and technology is impossible before its existence, but nowadays, it's real and it works better and we are hoping more development for the future generation.
Technology evolved everyday and we adopt on it, in crypto currency we also adopt on it and it will bring our future as its best technology to people to used.
