Today while I was out, I saw a guy at a busy intersection holding a handwritten sign. Obviously, I assumed he was panhandling, because people frequently do that there.
As I approached, I saw that his sign only had a URL on it. Out of curiosity, I visited it. Turns out it was some bitcoin mining scam.
While this was definitely a novel marketing approach, I wonder how they figured this particular tactic would instill confidence in anyone...
