Airdrops is good way to earn money without investing, also when you start
Name me any airdrop you have taken part, that brought you more than $5 or $10. Please give up-to-date info, or something at least half a year old. Dont give me random project names that you have googled, or mention 1inch airdrop or something from 2018-2020. I need something fresh. But I dont hope that you will name me something, because no one gives free money now. Projects dont have spare funds for that. I've been monitoring airdrops and bounties for a long time and havent seen anything profitable or worth spending time lately.
I have to say you could check the data on the previous ones so far, like probably for the past 5 years or so, and can find over 100 projects that was profitable, or at least over 10 bucks to follow up. However, that doesn't mean that it is a good idea, because we had 100's of them per month for the past 5 years and that is why the batting average is quite low.
If you have thousands, probably maybe like 10 thousand of them out there, and only 100 of them made you money, that is a low chance to win something. This is why not many people get super happy about it, you should be trying to avoid that as much as you could and instead find "sure" things to spend your time on.
