Some airdrops asking for AML/KYC with airdrop estimated amount for less than $5. Will you sign up?
What questions is this seriously? Of course I wouldn't. Don't give your details for that low sums of money, have in mind that ICOs can turn up to be scams and at the end of the day you might not recieve tokens but they will have your details. Anyway even if ICO is real they can sell your data or if they get some database breach your details will be leaked. Always think twice before providing your IDs.
This is serious. I saw many examples like that. I don't see the point why you should provide your details for a few bucks. I can understand if you make a big purchase during the ICO. Then maybe. Also KYC can make airdrops more fair so that one person won't claim an airdrop from several accounts. But overall, KYC for airdrops and bounties is definately not a good thing. Who knows what they will do with my info and absolutely no guarantee that you will get tokens at all.
Moreover, some airdrops and bounties conceal the fact that you should complete KYC and tell it at the end of the campaign.
