I do not agree with you man. Airdrop is not free at all. For getting some airdrop coins we need to do some tasks. Without compleating the task no one can able to get airdrops coin. I have seen, most of the airdrop asked to follow their Twitter, join at their telegram, Tell us to make some post on twitter, and retweet their post. Maybe for getting airdrop coins, we need to do a little task, But it's not free. No one will not do this kind of work free of cost. Investors not risking their funds by airdropping. if you think that, You don't know how airdrops work. Airdrop is a great marketing strategy. In this way, the team gets a lot of followers and they can grow the community. The airdrop was very hot topics a few years back, But nowadays most of the peoples avoided airdrop. They thinks it's waste of time.
