Which blockchain startup startup currently is the most successful? I see that the projects are not yet in business, I still have to play at the traditional casino house, namely KU Viet in Vietnam, their services are still far ahead of all blockchain.

I like Funfair but it still hasn't had a breakthrough!

But business is a big deal, I've seen many projects appear then disappear: Ethereum Lottery, Quanta Lottery, True Lottery,  KUViet lotto...

This project is died, like many other projects, it is dead, actually these projects are far behind a small branch of a betting company.
