Aside from Bitcoin, ETH and BNB that concept of your is true, there's no assurance that old project will bounce back to it's last ATH but if you are willing to gamble and take that big risk, who knows fate brings you luck and the market will favor you with those old or new assets that you choose, again, there's a big risk when investing to this type of volatile market, the only thing that will allow to grow is your own experienced with the current market.
Maybe that's the point? Having btc, eth, bnb and busd on your wallet means that you have 4 things which you know that will be great in the future, well not so much BUSD because dollar loses value but thats mainly for being ready for any crash so that you could DCA if that happens.
Do you really need to buy into any other "big" name one? Like sol, ada, matic, avax, and whatever else? Should you? Should you invest into something that is even lower? Who cares about these? There is really no reason for people to invest into tiny cap stuff. I'd say just invest into the four I named, and just keep it that way, stake them if you can, and have a very long term hold, like over a decade, even two if you can.
