The only ones that you are sure about the way the airdrop works are $GRASS and $EIGEN, they are both based on points.
$GRASS you just need to leave the plugin running in the browser in the background, you don't even notice it, and it starts data scrapping and farming points.

Use referral for extra points.
$EIGEN is also point based, you just need to restake ETH on a protocol, I use EtherFi (which is why I got this airdrop today), it's really easy, just go to "stake" and stake ETH.

Use referall (have no clue what it does XD)
ZkSync and ZeroLayer don't have known point systems, but I try to transact on both of them monthly.
ZkSync I normally transact on SyncSwap and am a Liquidity Provider in ZeroLend (which also rewards ZeroLend points)
ZeroLayer I transact on StargateFinance and am a liquidity provider.
Thanks a ton.
I will follow what u said.
Actually I dont have ETH. As such how much ETH needed??
