I just skimmed these, but on the second poster-- "the rewards to you can be substantial wealth"
Quotes likes that are why people characterize bitcoin as a get-rich-quick scheme or a ponzi scheme or whatever
This. If I read "get in now and become super rich!" I wouldn't give it a second glance.
I do, however, think the investment aspect of Bitcoin will play a big role in its adoption, but I would suggest rewording that part of the flyer.
Also all the different colors, highlights and font sizes makes it seem unprofessional.
