Up till now, the easiest giveaway I've seen is AGROTOKEN
You just need to have WAVES wallet and fill the simple form listed in this thread

I received 50 Agrotokens, and you can check my short video how it's possible to sell it on WAVES
(Actually then I canceled the selling order, I did it for test and educational purposes)
Very useful video. I didn't know how to trade of waves tokens and now I know it. Although Agrotokens I would rather hold on. When I get it ofcourse:)
Yes, I will also hold Agrotokens
That's great that my videos are helpful, I'll produce more!
