Why were people so bullish on Cardano earlier this year, but now people don't care for it?

ADA was so hyped up earlier this year, and people had legitimate reasons for supporting the project.

Now people don't care for it. Why is that? Has the company failed to deliver what they promised? Are there coins that have developed further/better than ADA?

I'm a total noob at crypto so maybe the terminology I used above is wrong... but hopefully you get what I'm trying to ask.

Edit: I guess I should've emphasized that I'd like to know more about the utility/tokenomics/tech, etc of ADA... long-term, is it a good hold? If so, what's your conservative guess for the price projections in 1 year, 2 years, 5, 10? Thanks!
