Especially with #play2earn concepts users are now able to receive rewards on chain and receive tokens that can be conveniently traded in DeFi and centralized exchanges. The value is created through offering utility to that token such as getting new game assets.
The problem is though that this play2earn token is highly inflationary because usually the supply is unlimited. Thus it is encouraged to earn, buy and use this one token. But it is unfavorable to hold long-term.
