if you look at the development of CARDANO I think it might touch more than $3, right now CARDANO has reached ATH at $2, I don't think it will be difficult to hit another new ATH in the near future, the smart contract released by CARDANO is also quite good
As I recall, the price of Cardano this year broke through $3, to be exact in March this year and you can still see it through the chart on coinmarketcap because $2 is not ATH for Cardano, but more than $3 is new ATH for Cardano, so it's not new ATH if only for $2 as of now.
I guess the question of whether it hits it again and goes beyond is another question. At the moment it doesn't look great against Bitcoin or Ethereum, so looks like it'll take longer to consolidate the fiat gains. I imagine it'll eventually get above $3, as one of the few coins that reminds in the Top 10 another so many years, but not before losing more value against the rest of the market.
