I tend to agree, but the guy forgets Monero.
It also doesn’t hurt to buy a bunch of other cryptos, possibly with some rationale and not just randomly. Follow an index, or whatever strategy, and see what happens. I made good profits with shitcoins like BNB and Chronos, not because I liked them but because I followed a strategy.
But you can also make it simple and buy only btc and xmr.
