In 2020, Bounty and Airdoropes brought me little benefit. Maybe I chose the wrong projects. But in my opinion, Bounty and Airdrop are now not a very productive form of earning. I prefer to invest in Bitcoin on it, I really managed to make some decent money in 2020.
How productive the campaign for you totally depend on what kind of project that you have chosen it. When you are choosing the right project and i do believe you can earn a lot of money but in another things when you are chosing the wrong project and that may bring you into the loss or your reward will worth zero value.
If we are learning from the past experience and we can know that about the future.
