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.
I'm amazed that this person was able to tell BTC will hit its ATH, however, he wass wrong with one thing. Alts are not dumping, some of them actually pumped and followed the bullish run of BTC such as eth and xrp.
