I will not completely subscribe to the idea of getting ride of all altcoins because there are few that are worth holding like SOL, ETH and a few others. There profit potential is high, maybe even higher than bitcoin but that does not mean one should go all in on them. What I will always recommend is anywhere close to 80% bitcoin and 20% altcoin so that one will minimize risk and maximize profits. This is how I plan to proceed, others might have better allocation.
