I had the same reactions as you did. A few where like a wall, I was explaining to them but they where almost not listening to me, because in their opinion only a tangible thing has real value (the funny thing is that payment in my country are mostly done into the bank accounts, so electronic money), some of them where really curious asked me about the cryptocurrency and in the end said that it's to much work and their not patient enough and others started working in the cryptoworld.
