Well, don't like to chase airdrops, but i receive offers. In that case, I do some research to the project and its potential and then join the airdrop (if the project looks good).
The only interesting airdrop that I found this year was Pundi X, however their airdrop is not free at all because you need to purchase their tokens to receive more tokens. Until now is working fine, but at the end of the airdrop I'm afraid that lot of people want to sell their earned tokens creating downward pressure to the price. So I will wait if price recovers after that.
