OK, tought I open a tread on what goes on at the bar.
I had two times someone was selling illigal private keys. When I helped I got one. I presume its better then going to the autorities but knew not where to sell it. Turns out that when you order a drink at the bar you might get lucky and some-one is looking for just such a key. And then you can sell it for 1000 satoshi! Not a bad deal for a drink that costed me 2 satoshi.
Same goes for a little girl who is lost. If you help her find her perents you get nothing, but when you just hand her over to the police you get 50 satoshi for your trouble.
if You also write your findings we can make the best choices and help eachother out :)
