SOSIP-3-Reduce airdrop claiming window

Propose by discord ID: Welp 🇬🇧#3616 with enough upvotes in discord. This improvement proposal solely considers if OpenDAO should reduce the airdrop claiming window.

At the time of writing this SOSIP, 295,066 Addresses Claimed account for 81.44% of the airdrop.

PRO: 1: Incentive unclaimed wallet to claim them and participate in OpenDAO. 2: Clear the FUD on dev able to create signatures to give certain address airdrop, which was designed to move all unclaimed SOS token to DAO muti-sig. 3: Community gets to vote on where the unclaimed SOS token goes, if this proposal pass, there will be another vote on what we do with unclaimed SOS.

Cons: 1: Lose potentially 500k wallets/users. (Could be wallets are lost or claim size too small, not able to cover their gas fee at current SOS price level) 2: People might remember the 30th of June and not be able to check the proposals and governance votes in time.

Please vote in the best interest of OpenDAO! Thanks for your vote!
