Yes I agree we are still in the wild west of cryptogaming.

I agree with everything you say as I have also been part of so many different Dapps and some times you are up and sometimes you are down.
Just like you I have also gone through a few of the scammy ones where like you say the Devs dump everything after a week.
That is why I like EtherStocks, there is along term vision as this is just the begining of CryptoGames
