Investing in the altcoin market at this time is like finding a needle in a haystack: utterly time-consuming and useless unless you stumble upon a gem or two along the way. Despite having stricter regulations and enforcement of certain licenses before creating a new token, shitcoins are still appearing here and there like mushrooms feeding off of other dying altcoins volumes. There are a few notable and actually useful altcoins out there such as ETH and some tokens under it but thats just about it. Besides, people dont really need all the fancy features and other bling-blings some altcoins come up with just to sell itself, so why bother looking for newer ones when you can just stick to the old stuff that just works?
I agree with your opinion, do not look for new altcoins that are not sure good, as long as ETH and Bitcoin are the best altcoins and the top level of other altcoins. Why look for new altcoins, ETH and Bitcoin are more potentially more convincing to invest, especially now ETH and Bitcoin are declining and I think all of you will benefit from your investment even in the long run.
