Now a number can be a maximum of 4 times a month. 100 each time, 1200 for three numbers.

Today (May 15, 2025), a new token $NXPC in the Binance Alpha zone has been airdropped, with eligible Binance users receiving a single airdrop reward of 400U+.

Adding up the 529U from the first two weeks of May, the current yield is 929U. Based on this trend, the conservative yield for May would be 2000U per account, leading to 6000U for a family of three, resulting in a monthly income of over 40,000.
Why? Because this is essentially Binance's monetization of liquidity monopoly. No other platform has the same bargaining power with project parties as Binance does. Because liquidity is monopolized by Binance, project parties lack alternative channels and can only accept it. Once they accept, Binance can monopolize even larger liquidity at almost zero cost, continuing to squeeze the survival space of other exchanges.
