You can pay attention to the altcoins at the top of the list. In addition to new items appearing. There may be a hundred-fold increase, but this requires opportunities, not to say that all new projects can be like this.
I have always stored Ethereum and BNB in my wallet, and I am looking at Matic tokens recently. I thought their development was pretty good.
It take so much time to do all the research if someone wants to invest on a certain altcoin(s) but I agree that ETH is the one that showed a good sign and potential even though some of these altcoins are leaving in the crypto space. BNB on the other hand has shown also a potential last bull run although the price continue to drop during bear market but I was hoping it wouldn't betray us during the bull market.
I think memecoins isn't a thing now if you asked for the best altcoin to look for in this coming bull run. There are bunch of altcoins that are present yet it needed some extra research if you want to find the best one that has potential this coming bull run.
