This is my calculation for remaining rewards for Metis.

I'm almost 100% sure that they will not drop everything for layer3 campaign, but expecting around min. $500.

I think interaction with the network itself is also important, for example, having more than 50 transactions or being active for more than 10-15 days, I think that 500 to 1000 dollars is reasonable for layer 3 tasks.

Yea, I do have that also, but for now they only talk about airdrop for layer3 quests. Maybe they will also drop for txns, volume and others.
