How much was arbitrum airdrop worth?

I'm curious to know, just how much was the value of the Arbitrum airdrop? Did it offer a significant amount to participants, or was it more of a token gesture? Given the recent surge in popularity of blockchain projects, I'm interested in understanding the financial implications of such initiatives. Can you shed some light on the potential monetary worth of this particular airdrop, and perhaps provide some context on how it compares to similar events in the past?
