The dump from the airdrop hunters won't mean a lot, as they will get pennies from this app. The total allocation for airdrop is being limited, and there will be many people called this as a scam.
If they get pennies then its okay but if they get huge amounts then it won't be okay. I heard someone who made around $20k by accumulating Not coin and if the airdrop is of same nature then things could be quite strange.
Those who get limited amount from airdrop often consider such projects as scam but that doesn't matters anymore because it's already hyped a lot and it may get the attention of the investors if it gets listed on a good centralized exchange like Binance.
I think after the airdrop, they will concentrate on the platform and features to keep the momentum going with a huge number of participants and limited allocation I don't think it's something that will make you money but free coins are the easiest way to build a community and with a successful as your your predecessor then you have a good chance to succeed.
