For me, cryprocurrency process seems to be long and still popular among the people, if we look at the crypto system is very good and sophisticated, now some countries have applied crypto system to improve the transaction system that is still not good. In terms of payment, transaction speed, transaction security and transparency. It seems like the cryptosystem will last a long time, and it certainly will play an important role in our technology, and this is a very important thing for us in today's best technology.
