Many encryption companies distribute free coins to their communities to increase the visibility of their projects, increase the current supply and stimulate trade. These free distributions are commonly known as "airdrops".
They are "reward" drops, which will reward you with tokens for completing simple social networking tasks (joining your Telegram group, republishing on Twitter, etc.). This offer creates a win-win scenario because the company gets free marketing and you get free cryptography. Others will reward you for simply holding a specific currency without expecting any reciprocal consideration
