Cardano is still overhyped even after the recent fall. There is no space for it to go up in the close future - it is still on 7th position on Coinmarketcap even if it hasn't implemented any inovation yet.
Not at all. Team is actively developing Cardano platform. You can check it from their github contribution. Cardana has a big room to go up, even this year. My favorite coin that will beat any entity in cryptospace.
