I guess, it has the unique revenue sharing program, CKM tokens are very cheap now - so it will mostly rise, especially in the start.
Airdrop and bounty hunters may not agree with you:) They always sell everything they've got.
Many big and successful crypto projects had airdrop and bounty programs too, if project is great, token price will rise anyway
Bounty and airdrop programs are not profitable for the blockchain projects in 2019. I don't know why CKM decided to make even both of them.
