Coin4Me looks a little sparse. Setting up a website devoted to giving up bitcoins geocaching is a good idea. In fact, all of the ideas presented so far are great but someone needs to implement them and track it (very time consuming).
Bruno, are you suggesting geocaching t-shirts? Some of the containers we found are not very big. I think this would be limited to the most remote ones. Here is a site we used and some of these would be big enough for that idea:
http://www.nevadageocaching.comThe link is down, CBH, but that's not what I was advocating.
What I proposed is an idea I've coined as
MovableCache (I see red is the new bold), where it's to the best interest of the shirt wearer to don their tees daily with hopes of having the QR-Code scanned, for they'll get a referral fee (share) each time. Each shirt has its unique QR-Code on it that recognizes the wearer as the affiliate. If two people had the same shirt but with a different QR-Code, once scanned by two different scanners, they'll be directed toward the very same site, albeit the affiliate would be different.
Let's see how this would play out to bring maximum awareness to Bitcoin.
Company X provides $30 USD to be geocached via Bitcoin at two distinct locations.
Geocacher 1 (among others) hide the first part encrypted.
Geocacher 2 (among others) hide the second part encrypted.
T-Shirt wearer is out in public displaying the QR-Code to be scanned, directly all scanners to the info on the site.
Finder of part 1 of the encrypted cache announces his find.
Finder of part 2 now announces his find.
At this point, all 5 parties are awarded an equal share--$6.00 USD each in BTC.
During the interim of this ordeal, many people were made aware of the advertiser, Bitcoin, and the site provider of this endeavor. An added plus is if all this was also posted on the three geocache sites I previously mention above.
Now, I know this idea needs fine tuning, but desired to present it in this brainfart fashion.
