2) Limited Time Benefits are extremely powerful. When players need to gain higher revenue, it will play an inestimable role. This kind of NFT has a limit on the number of times to use (such as once a day). When the time limited benefits of an NFT is activated, the NFT immediately enters the CD (Cold-Down-Time), and the buff cannot be activated again until the CD is ended. For NFT in CD, even if it is traded to another player, its associated benefits cannot be activated either.
