The two projects Snowball and Fireball on BSC each have their own characteristics in token economic design. The buyback mechanism combined with the burn strategy forms a unique deflationary model - by repurchasing and destroying tokens in the market, it not only reduces the circulating supply but also provides support for the price. This type of design is relatively common in the Binance Smart Chain ecosystem and reflects the project party's consideration for maintaining long-term value. Whether the deflationary mechanism can effectively play its role ultimately depends on the actual operation of the project and the level of community participation.
