Im from Australia. A lot of my acquaintances have hear about BTC, but almost no one use it because they think bitcoin is a scum or they dont understand it.
I once told my Economics teacher about bitcoin and she ended up asking me whether it is a scam or not. I told her about the coin's price volatility, the ATH that happened on November 2013, and the bad stuff about it among others. She couldn't comprehend to the technical stuff about bitcoins so I went on explaining it the noob way. Different stuffs, concepts, pros and cons about bitcoins and in the end, she'll end up asking if it's a scam or not.
Maybe people aren't ready yet on accepting new things and concepts that are against the norms of this society.
