You must have heard of play2earn. Right? Where you can play games to earn rewards that could be converted to real money? If you have, play2earn uses the GameFI technology. With GameFI, players can earn by joining different game activities like tournaments, winning battles, completing some tasks, and even collecting some rare items (that can also be traded for an in-game item or sold). And all of this is done by smart contract so it is transparent and safe. You can simply say GameFI is the combination of gaming and finance.
