Tron, EOS, Cardano and BCH are all good altcoins to me, this is your own decision OP and I believe everyone is free to make theirs, all these altcoins you called outdated are better than 90% of altcoins that got into crypto since 2018, well the choice is always yours
Exactly, I believe every one in crypto space have their own view to why they consider some project and consider them outdated because to me, what good is Dogecoin? but we saw what happened some few weeks ago and this will happen occasionally to some projects even when you classify then as outdated because some one or group took a sudden interest in them. How many of us in crypto actually use those cryptos for what they where developed for? like the in-Game coins/token, do we really acquire them to be used for gaming or for trading and make money? i bet your guess is as good as mine.
Dogecoin only pumped because of Elon Musk's tweet. No other reasons than that.
From OP's post, I still prefer Cardano to be a good investment. I've known it for long and they keep up to date with their roadmap. Some of those new innovative coins are still overhyped to me so I don't plan to buy them yet until a massive correction happens. A coin that increased more than 50% in less than a month is likely to dump soon.
