Do not trade Alts with BTC these days, You will just lose
I do not recommend to trade alts with btc these days otherwise you will be just loosing your money. As BTC hitting its ATH, the prices of alts are dumping even if it is BNB or any other coin whichever was stable in the last months. Just trade BTC/USD only.
its depends on our pupose mate, if we want to collect more bitcoin i think trade altcoins in bitcoin pairs is the best idea,
because bitcoin price could grow more in this year my friend
