The bounty program is more profitable now than airdrop but they looks thesame...
Participation in the bounty can be profitable only if the payment is made with a coin that is already traded on the exchange. The most preferred coin for payment is bitcoin and ethereum, but this form of payment can only be found in the signature company, which requires a high rank.
Agreed that airdrops and bounties are worthless if the token has no trading pair on an exchange. There are a lot of projects that just want to pay out in worthless tokens for sure. I didn't have that issue with CNDL because it is traded on around 6 exchanges. Many of the airdrops I received where a long time ago on STEX exchange. They gave you airdrops in your wallet that you could trade if you wanted to. Exchange airdrops are a good idea I think.
[Yes its true that bounty programme and airdrop are beneficial only when their tokens can be converted to coins and traded. Majority do so. Have you tried Mallconomy]
