I heard it a year ago. In 2017-2018 had appeared first decentralized exchanges, like idex. I don't find any changes in my trading. The same functions and operations. I think 2019 will be a year of something more impressive.
I hope so. But now the problem is Crypto becoming unpopular for decreasing its price. Crypto going to Valueless, people getting disappointed. They expecting a better value but that's not happening. 2018 was a frustrating year, so hope 2019 will be best.
