I can't think of a better way to grow interest (re. raise price)... we should all be tipping newbs with a link for sign up.
It's in our power to increase awareness and actually make a tangible difference!
I can. Show them the benefits of using bitcoin, don't give it away for free.
If you give away something of value (in this case bitcoin) for free then the receiver will likely just sell it for fiat cash
If I give away 50 cents worth to 20 people there's a good chance that 4+ will become interested enough to start a wallet... especially if you explain the potential growth.... hell that's like two beers or shoveling my own driveway... money well spent.
