What Made You Believe in Cardano?

I see a lot of investors who believe in Cardano coin.
There is also a large community that supports Cardano coins.
But I have a weakness and that I don’t know what everyone needs for Cardano coins.
Can you guys share some advice in this thread about Cardano as to my knowledge this Cardano is always in the top 10 of Coinmarketcap rankings.
