Just the fact that anyone can win money from playing a game is amazing. Until now you either went professional gamer/streamer or you could only spend money in the game and not get any of it back.
It´s just my opinion, but this is the dream and all I´ve searched for 5 years ago when I really spent a lot of time playing, but couldn't waste money in the game because there was no potential return. Now the return in even higher than the investment... :D
