In NFT promotion modes of the class LOOT project, the quantitative increase in the chain time is the best way. There is a big problem in the way, the problem is that the previous growth is too slow, and the number of subsequent quantities is flooding, just like an encrypted cat. And in realities use breeding creatures, there is a life cycle, and it is old and sick. So didn’t lead to too flooding. Therefore, if NFT can also have life cycles, can you have birth? Is this more in line with the Yuan Universe.
