Cardano might probably going to end up being the next EOS during the next bill market.
So. I can't advice you to invest in cardano now.
Also, it has been a smart contract network for a long time and till date. Most Devs don't use the Cardano network. Although, I'm just saying from my point of view.
I understand why you are comparing ADA to EOS, to be honest ADA is quite slow in developing their blockchain, they are constantly lagging with updates which makes me sometimes bored to hold ADA.
But I don't think it will be the second EOS, EOS was bad from the beginning after the end of the ICO, it seems like it raised so much money that it blinded the developer. They have so much money that they don't need to put in the extra effort.
ADA we still have hope because the developer is still working hard and always has notice of his delay. I think ADA is still worth the investment.
