What are “play-to-earn” games in cryptocurrency?

Play-to-earn games allow users to play and earn cryptocurrencies and NFTs, which can then be sold. Some users regard blockchain games as the main source of income. But games usually require investments, since at the first stages it is necessary to purchase in-game characters. The funds received you can withdraw through the NFT marketplace or through exchanges such as Binance. The most popular blockchain games include Axie Infinity, Smooth Love Potion, and others.
