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to me, this is your own decision OP and I believe everyone is free to make theirs, all these altcoins you called outdated are better than 90% of altcoins that got into crypto since 2018, well the choice is always yours
Well I do have some trading with these coins and so far I have earned some profit out of it if you are going to ask me. I do think though that the OP might be suggesting the other coins because he has already invested on these aaaand wants to market it to us so we can be convinced as well to buy? Not sure but that is how I see it. Anybody promoting something is always a marketing stunt for me and I respect that, it's like reading a commercial on a forum. You watch it and still up to us if we want to buy it or not.
