As I've understood even a lot of projects hold airdrops just to get people's information, isn't that right? Well of course, by airdrops they can increase their visibility and also increase their followers and supporters list, but is there even another reason why a project would want to hold an airdrop if not for gaining access to people's details?
I think the surrounding reality is cruel and at the moment airdrop is needed solely for marketing purposes, obtaining subscribers in social networks, obtaining consent to send an email. I do not think that you, as an investor, look positively on the free distribution of tokens...
