It is 50 cents.  And if 10,000 people do it then it's $5,000.  And if another 10,000 people do .1 donation then it's $500,000.  So it is a little money or a lot of money depending on point of view.  The easy milestones of Q4 2017 seem to be met.  The more difficult milestones ahead will make or break this thing.

Now, what is interesting is the road map quote of "major exchange" by Q1 2018.  Tip: "Major Exchange" is not ethdelta, cryptopia, not even hitbtc.  A "Major Exchange" is something in the top top of volume exchanges such as the top 3.  So far, I don't see this listing happening unless there is more transparency from developers since a "major exchange" would entail revealing more about the devs which are quite anonymous at this point.

I don't see any pictures or records otherwise to prove existence of real people.

That could all change though.  I hope it does.  Or, I hope that this actually gets listed on one of the top 3 volume exchanges and that would dispel a lot of doubt despite dev anonymity.
