Question about Stake

Hi, I read in this email from the creator of SNX A little dash of hÖpΞm that 4 Airdrops will be held and project tokens will be distributed to SNX holders and stake holders. Attention question, can I stake a SNX token on the yearn finance platform and qualify for Airdrop? Also, why is the SNX staking updated every 7 days on the Synthetix platform? is it possible to somehow zasteykat and just forget?
