I have some altcoins from early 2017 and some BTC and ETH too.
Does this means that you missed the all time high? if you did, well I feel sorry if you do but if not and you just want to diversify again, good choice of looking into those coins but not all of them should be preferred.
When i bought in early 2017, Statis, Waves, Ark and ADA was popular, how are these coins today?
Cardano is still making it's own noise while the others, I don't think that they are still popular these days. Are you that it's statis? I can't see a coin that has that kind of name. I see, status and statis euro though this is a stable coin.
What are your thoughts on Basic Attention token(BAT)? I have used the brave browser for a while now and it seems good. Cardano looks interesting too.
They are active though and there's a development, I don't have them but if that's also a coin that you prefer then I think it's okay.
