Three weeks of playing a play to earn game: this is my first impression about Upland

In the last period, as I am more and more interested in crypto, I discovered the NFT concept. And by searching in detail, I also discovered the concept of Play and Earn games.
Play and earn is a “new” concept of online games, that allows to play and earn real money. But you don’t gain real money directly (like lotto, gambling, and other classic money games). You earn NFT (non-fungible tokens) that you can sell for crypto and then you sell your crypto for classic money.
