Right now so many good projects are at 90% down from there all time high, same is with cardano. But the thing is Cardano was over hyped in the first place itself. Till now they haven't provided a working platform on which apps can be built. Whereas there are already so many platforms out there who provides this functionality and they are really good one. I personally don't see cardano yet as a good investment, for me it's still highly priced at least by 3x if not much.
