It seems that Alpha airdrops will be based on a points system in the future.

In the mobile app, click the bn logo in the upper left corner, click 'More Services', then click 'News', and you will find 'alpha points'. It is estimated that in the future, participation in IDOs will depend on your points, which will force everyone to trade bn alpha assets, and this is actually very beneficial for on-chain assets.

(Exit the program first, then follow the steps to find it.)
