BNB has a high demand before each airdrop, with a high probability of rising or being resistant to decline. After the airdrop, there is a strong demand for cashing out until the end of the airdrop, which will likely lead to a drop. FDUSD is the same. You can buy FDUSD during the airdrop window period at around 0.98-0.99, and after consuming half of the airdrop in the mid-airdrop phase, sell it at a little over 1.0. Moreover, there are no transaction fees for FDUSD trading
