Excellent information although I believe that what you get at Tron is not a gift but part of the reward for your publication. Airdrops are a way to get some tokens for free, although most have very little value or are not priced on the market and some are even never released. However there are also those like this Tron that have been solid for some time on the exchanges and are a good opportunity. I guess I get in on the release since I have over 100 tokens.
