Airdrops and Bounty's for the most part just attract the people you dont want - those who dont give a toss other than to get free coins to sell them as soon as they can.
Start mining Webchain, its easy and you get a good return for even low end hardware or just buy it

. Its around .01 USD so you can get so many for very little investment.
Not always is like that. You can make smart campaign so only people interested in the projects get the coins. Also I think mining is just mandatory for everybody who thinks seriously about WEB.
