Easier? Ok, let's look at the current requirements of different airdrops/retrodrops: standard subscriptions to social networks and regular posts/reposts, staking and locking of certain amounts (in pursuit of TVL), the need to have a certain number of project tokens or a native token of the chain on the balance, replacing a direct airdrop with lotteries and random samples, in the end KYC. I can’t call such a drop “easy” and especially free.
