Obvisouly for the free tokens, but other than that, what else incentivise you taking the time to do the airdrops? Most of the time, I found that the airdrops often give little to no return. I just started to get into the crypto thingy. I feel like it is better off finding those ICO projects and considering investing in rather than chasing like 5 dollars?
It is not wrong if you take part with Airdrop which is legit so as what you have done can be paid off, taken part with airdrop only takes a little time, you just simply share the link they ordered on Twitter or on Facebook, most of it is just that. You can also while following the ICO project because there is no arrangement that requires you to use their signature.
