Nothing can be expected more if we expect limited airdrop. It is very rare or even not available for now airdrop that can provide high ROI for each participant. Maybe the solution is not to airdrop, but to projects that offer rewards for every coin / token holder, and I think it will provide a higher ROI, but with one condition the project must be a project that can lead to success, it can be said until it is listed on the fund market has a better volume if the coin can occupy the top 10.
