I recently participated in some self airdrop howbeit with very little fund as low as $5 each by sending ETH and getting some tokens in turn.
I would later discovered that some deleted their social media accounts and eloped with funds. Some that did not run away made it to the exchange by promising huge airdrop to be voted for their listing. But would later dump and abandon the project thereby dashing investors hope.
I see that these new scam have no real project to execute but to just collect Ethereum and amass BTC at from the exchange.
Have you ever participated in any self-airdrop? I want to hear your view about the outcome.
I will never go with these kind of airdrop because it is a clear scam using old easy way so better to find trustable airdrop project with good team behind and strong active community then you may think to join for free just to do marketing through social media or bitcointalk .
Lesson learned : Never pay for airdrop or ICOs .
