Been talking about Bitcoin since a bought my first for 13usd 2011. Some are a skeptical, some don't even begin to understand it, but some are actually quite intrigued. The total number of people I convinced to actually buy some coins: 0. I do sometimes enjoy saying "you should have listened to me back when it was at 13usd" though
Don't they respond by saying you got lucky and better sell now?
Interstingly some of them seem to believe in it but they still haven't bought any, don't really understand why. They're definitely not too poor to risk loosing a little bit, and some do invest in gold, silver and stocks etc.
