Cryptocurrency is creating a new era that has never existed before. It has a function as an alternative for real money. So cryptocurrency leads to the end of an era but leads to the beginning of a new era at the same time. Cryptotrading begins with the beginning of a new era. Cryptotrading is trying to create a system that makes it easier to trade Cryptocurrency, like the system that barter of goods had before. In the past, barter of goods was done on a person-to-person basis, and now, trading can be done easily on currency to currency basis via Crypto Trading System. If individuals trust each other, a completely new transaction is possible with the information they trust.
