There is no best crypto to trade with now. My reason is that most of the token now the price is really bad and many people dump most token however, what I can advice you is that if you buy or invest now just keep till market rise.
There are a lot of good coins in the cryptocurrency market that you can trade to make a profit, so it is important that you find the coins. I think that researching and choosing the right coin to invest in this market is the key to the success of the deal so it needs to be invested seriously.
