Is a valuation of 4 billion for Pump high?

Although it's quite foolish for Pumpfun to seek to raise 1 billion at a 4 billion valuation, having already made so much money, who can refuse more money?

From the monthly revenue of the protocol, Pump's revenue in the past month was 70 million, slightly lower than Hyper (4B FDV) and Uni (6.6B FDV), so a valuation of 4 billion seems reasonable.

Additionally, considering there will be a 10-20% airdrop, which means 500 million to 1 billion going to the young players, it feels okay?
