A new and promising trend in DeFi, the Play-to-Earn concept, has been of particular interest to investors of late. This concept represents an opportunity for users to not only use standard financial instruments, but also the opportunity to earn money simply by playing blockchain-based games. As a rule, in such games, the user has the opportunity to receive as a reward classic tokens or NFT tokens, which are almost always of some value in the DeFi market. Currently, the field of blockchain games is just at the beginning of its development path, and the DeFi market has yet to reach its peak capitalization values.
