The fact is people around me doesn't know what bitcoin is. Even well experienced and educated teacher also don't know what bitcoin is and when they hear about it they think that is useless and so they don't care about it.
Most teachers aren't techy and it isn't a requirement for them to teach. There are even techy people that don't know bitcoins. It's usually teenagers that know bitcoin because they all want to earn money. I remember when there was a seminar in our school and someone introduced bitcoins to us. People just don't get it. The guy was trying his best to let everyone understand it but I think it would really take some research before you fully understand bitcoins. Even the teachers that were sitting in the front seat are all unaware of what bitcoin is.
