$snowball is a new model launched by pump. Recently, there haven't been many market makers willing to operate the pump, so pump directly introduced automated trading Bots, collecting the transaction fees directly into a working Wallet. They use smart contracts for low buy high sell to add Liquidity, which is quite innovative. It directly reveals the operation, significantly reducing the difficulty of pvp. The only downside is that if the hype is insufficient and the fees are low, there will be no pump effect.
