You would not like what the masses say about bitcoin. Bitcoin was mentioned on some website in the comments, and the poster was teared to shreds by "the masses" who all said it was a pyramid, ponzi, get rich quick and something like that.
That is true, but that is only because of mis-information.
The masses do not yet understand that Bitcoin is a method of transacting leaving all middle party (and unnecessary expenses) out.
Bitcoin should NOT really be seen as an investment (not at this point).
So basically it's a replacement for banks, VISA, WU, etc. but with super low fees.
So for the masses to trust Bitcoin then the masses must first understand that.
Once they do understand that, then they need to be able to go from cash to Bitcoin, which is something that is not that easy at the time.
We have localbitcoins and several ATMs worldwide but it's not enough.
And for mass adoption we need (more) widespread services for: Cash -> Bitcoin.
Not: Cash -> Bank -> Exchange -> Bitcoin
