such free token giveaways are perfect to increase user base. I think this will help them a lot to increase the number of users.
Some people may be skeptical about $5, but I have seen free airdrops that started worthless but were worth hundreds of dollars eventually.
cant agree more, some of my friends said that they dont want to sign up for pennies... but you cant know how much this quick sign up will be worth in a few years. If I find an easy opportunity to get some free coins to any project, I always use it. We can never know what the future brings
