I was just about to write this as well! Right now I am pooling all my SPS with my DEC for the airdrop. In my daily SPS airdrop I just swap half of it for SPS and pool it again.
However, one has to be wary of the concept of impermanent loss when pooling your assets in DeFi! Nonetheless, the return is much greater there.
