From all the opinions and tips I've heard so far, I've come to the conclusion that $BTC $ETH $SOL and XRP are essential coins for your portfolio, whether you're a new investor or not. Do you agree with this? If so, why? And if not, which ones would be the "indispensable" ones?

(The WLD coin shown in the previous post came from the World App campaign, and I still don't know what to do with it.)
