How many Jupiter airdrops will there be?

Could you please clarify the context in which you're asking about "Jupiter airdrops"? Are you referring to a specific cryptocurrency project or token distribution event? Generally speaking, the number of airdrops a project may conduct can vary greatly depending on the goals and strategy of the project's developers. Some projects may only conduct one large airdrop, while others may distribute tokens over a series of smaller airdrops. Without more information, it's difficult to provide a definitive answer to your question. If you could provide more context or specify the project you're referring to, I may be able to offer a more precise response.
