Yes you are right. The competition in the exchange market is very large. But not really when a massive influx of new users into the crypto market begins, the current exchanges will again not cope. Remember the end of 2017.
Now we remember 2017 as a fairy tale. These were the times ... Bitcoin could grow by 1000 bucks a day. And the whole market grew like a rocket. I hope that 2019 will not disappoint us!
