"Please read the post. Only tokens in non-custodial wallets will be counted," Pump Science said in response to a community user's question on the X platform "Are there airdrops for coins bought on exchanges?" Previously, Pump Science said that BIO Protocol will airdrop BIO to holders of URO and RIF. According to its token economics Litepaper, a total of 800 million tokens will be issued according to the Bonding curve, and about 50 million tokens will be airdropped proportionally to holders of previously launched Pump.science tokens (URO, RIF, etc.). Airdrop allocation is based on the time-weighted average of the holdings in each wallet during a specified time period.
