You get 2x airdrop points on POOLED DARK ENERGY CRYSTALS, so since you sold half of your DEC to provide the 50/50 liquidity pair requirement you still got double points but on only HALF of the tokens you started with.

The best way to use this strategy is to hold whatever amount of DEC you are comfortable with and then use the SPS earned from the daily airdrops to pair off whatever amount of DEC is required per day.

This way you can continue to hold your SPS tokens if you think it will appreciate in value or maybe want to stake them later. Otherwise the option would be to sell the SPS as it comes in daily and buy more DEC and it would effectively earn you the same amount of airdrop points without risk of impermanent loss from the AMM pooling.
