I think this year's best exchange is of course binance , huobi , and I think cukoin I think they will be the first in volume this year
indeed binance exchanges currently have trading volumes that are very high every day and can even be number 1 of all existing exchanges, from here showing that the exchange platform that has just appeared can be number 1 and defeat some old exchange places.
These 3 markets are very confident with their own coins and offer various benefits. Actually there is another name that is quite good like coinbene, the volume is not as good as the others, but it is quite interesting for daily trading, but unfortunately they are hit by the news about losses due to hacking.
