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?
You can earn good money in airdrops if you will have a spam entry, however it is prohibited. No ICO will ever give you a huge amount of money for free. And, only few airdrops have value some are just trash, so it all depends on luck.
