I think that they should think about an airdrop campaign that will attract many users to the community.
Airdrop is not so popular, but to run the bounty program, it would be very good.
Airdrop is a great tool for marketing and attracts a large number of people in your social networks, with almost nothing to spend. I believe every project needs to release the Airdrop.
I agree with you. Airdrop is needed. For a young exchange, I think this will give new users who will use the exchange, because they will have a favorable exchange price due to a lower commission.
