launchpool is no more profitable unless you have min 15bnb or so ... it use to be earlier but not anymore

I stack 400usdc and all received is 0.92 Huma from more than 12 hours stacking.
The average airdrop of stacking is 0.0022 per usdc every hour. 0.0022 x 400= 0.88 should gaven to me every time but after more than 12 hours all i got is not even 1 Huma.
