What do you think about ADA?I

As after researching from the communities, I found the following opinion:

I think it will be out of the top 50 by then and worth only a few cents.

Cardano is a very hypothetical experimental project that never really made something that really worked as promised. They have way to many Cardano coins, 45 billion, projects with more than 1,000,000,000 coins never grow fast in value per coin. In my opinion you can better sell your $ADA asap and buy projects that actually accomplished what Cardano only promised with way less resources, like Solana and Syscoin.
