As long as cryptocurrency lives, play to earn game will continue but the demand will not increase because people who played for crypto are definitely dissappointed with the amount they receive from the game. Like for example bling games that can pay a small amount of satoshi or ethereum. I had a friend who was trying hard to play that game and after a few months he only got less than $20 worth of crypto. Well, playing those games is also enjoyable and pastime.
