What will be the least value that one have to be stake to get the rewards? And how can it be much profitable to stake it?
Staking LP tokens aka providing liquidity does not qualify for the airdrop. After thoughtful consideration and appreciation for the liquidity providers, the airdrop to $KEYFI stakers will be most beneficial to $KEYFI. If you are currently providing liquidity, you are welcome to remove some of it to stake the ERC20 KEYFI token before the December 9th snapshot.
