From a reputation perspective, some projects' practices are quite good and indeed have the meaning of learning from leading projects. However, to be honest, I don't see any real utility in this approach.

The key issue lies here: firstly, this is essentially a token discount sale based on users' affordability, in other words, a price tiering. Looking at the NFT side, the pricing logic becomes even more tenuous. Think about it, if the price of NFTs entirely depends on individual purchasing power, how can this model work?

Don't talk about innovation; such a design makes it difficult to find a healthy market equilibrium. From both the user perspective and the project's sustainability perspective, there are obvious logical flaws.
