So, you think that there should be restrictions on what BitCoin lets us buy?
Why even have a crypto currency if you don't want to really use it? I think you should just stick to paper money.
I don't think he meant you couldn't, but probably it shouldn't be the first thing you go up to strangers and use to explain bitcoin. I mean, maybe if you really know the person but as a general tool, prob not.
It isn't easy to get people onto bitcoin. I've been talkin' it up to my family/friends for years, have bought goods (not silk road!) with BTC, bought things FOR them with BTC, shown them the increase in value....and they still think it's some kind of weird pyramid scheme or something. The biggest facepalm moment was when I bought my dad something for his birthday off bitcoinstore.com and explained how I got a sweet deal for it because BTC is more efficient and all I got was a "Yea, because it fell off the back of the truck heh heh heh."
The best thing you can do is just play it cool, don't sperg out, and just keep at it.
Though, getting someone to sell YOU something for BTC is really good too. I have gotten a few peeps to at least take it seriously once I paid them some coinage.
