Cardano still ranks 7th according to coinmarketcap, of course ADA is still very suitable to be a future investment asset,
moreover, ADA's price is still relatively cheap and you can buy ADA at the current price and then hold it, then you will get x2 profit in the future.
don't worry about the development of the Cardano project, even though this year ADA hasn't shown good progress and even looks quiet, but I'm sure ADA will surprise us.
