I have been participating airdrop for almost eight months already, and all I have receive is just some of the tokens, sometimes much and sometimes less. All they say to me is that don't collect some airdrops because its a total garbage. But right now, I have to make some investment on a specific ICO, and luckily, almost all of my airdrops got a value, and I collect it all, and I got accumulate almost 100 usd just in airdrops. Airdrop can help you, if you just have to be keen and patient with it.
What is your experience regarding airdrops?
Airdrop is like free money. If you have free time then keep doing it, nothing to lose.
