I played and I`m still playing bunch of these games that pays some cryptocurrency, but I didn`t find any game that pays enough to be worthy of my time and energy. I play a game and I lose interest very fast. Until now I didn`t find any crypto game that keeps me playing for hours like I can play a game that I like. I still wait for something big to come in crypto gaming industry!
That's the biggest issue - games need to be fun! It's nice if players don't lose all the assets they've earned through their time spent, but in the end they'll only keep playing if the game is actually fun.
