Bnb can be used for transaction fees, and discounts on fees are its fundamental value. Encouraging transactions is how to increase the value of Bnb; how can that be considered digging for roots?
It's simply that if you don't trade alpha, you won't get airdrops and you'll feel bad.
I don't trade alpha either, and I don't get airdrops, but I only feel a slight regret; I quite support Binance's approach. If all airdrops go to Hold, launchpal, etc., everyone will just use BNB for financial management, but no one will use Bnb. What has no use but promises huge returns? It's a Ponzi scheme! It's multi-level marketing!
