Altcoins can be so profitable but the profits will always come under certain conditions. Lately, I discovered that we should not only look for the best altcoins to invest in but also be fervent in monitoring the progress of our coins, and their woes. If not, altcoins will run the investor down. This is to put it to the main OP and you who are listing these coins/tokens to keep the right watch, that is my late resolve about cryptocurrency with these days' behaviours, unlike how many investors will just be buying and buying but are being careless about the monitoring.

Nevertheless, I can agree with some of the ones you listed above as good, and even though I know all, I stopped giving relevance to some of them over time, altcoins are too many to keep track of them all. However, one coin I will not think of at all in this list simply because it will behave like Bitcoin is Ethereum. I do not see much gains in the investment of Ethereum unless you want to trade it on the futures market. Regardless, altcoins like SOL, ONDO, and NEAR will always be my picks in a list like this.
