Can someone tell me why ADA can be the 3rd in market value??

Until now, I still don’t understand why ADA can rise to the top 3 in market value.

The smart contract will only be launched in September, and the ecosystem has not yet developed

Compared with other public chains, the progress is much behind.

In such a competitive environment of the public chain track, can it really grab market share?

For example, the recently skyrocketing SOL, backed by FTX, has developed step by step, and the ecosystem has also begun to be complete and gradually connected.

Now it's only 10th in market value

Some experts who study ADA can tell me, what is so attractive about ADA that makes the market be so popular?

P.S XRP is even stranger, it's almost 2022, why is it still 6th in market value?
