My friend introduce me about the airdrop campaign, it is good, but you can only have a small amount of alt coin for every airdrop, and the price equivalence of it in the market is just minimal. And in terms in participating on it, some airdrop is a time consuming. May I ask does participating on it gain big earnings?
There are airdrops that are worth it and there are the ones that's just wasting your time. If you want to do/get airdrops, chose the ones (projects) that has a potential and will not make you do a lot of work. I tend to join airdrops who just makes you join their telegram group, or follow their twitter account and retweet a post and then they get some of your info (bitcoin talk username, profile link, telegram username, erc-20 wallet address...) for them to send the airdrop after their project/campaign. Yes, there are a lot of people who earned money from airdrops especially when the project is a success and the value of the token is high.
