Same here, I traded for it via a trading platform. I used the reward I got from a campaign. And up to now, that's my main means of getting Bitcoin and Ethereum. Those two coins, I think, are the most valuable to held because they have the better chances of yielding good return in the future. Thus, I invest the rewards I get from the campaigns I join in those coins, and some more, that I think could give me a better return in the long run. It's not that I don't trust the new coins, but it's just easier to trust the established ones.
