it looks like you have to wait quite a long time or maybe it can be faster to get your GFN if you are a participant in the airdrop.
because the team itself has announced that each snapshot participant will get it before all snapshots are finished.
And I guess you know how many snapshots there will be in the GFN airdrop. this could be faster, but in the worst case, we will wait until all the snapshots are finished.
