I have been in Bitcoin for years. but I am more closed and silent. I don't promote bitcoin to people around me. Because bitcoin has a risk I'm afraid that I'll be blamed if there is a loss ... because most people don't want to take risks.
It's good to be closed and silent becasue the world is full of risk. But there shouldn't be such closed to that instead that with the knowledge without sharing to others. It's good to share what you know with others in this industry which means you are rightly impacting others with the right or needed skills for their lifestyle. Most of my time are for those who wants to learn one or two thing about Bitcoin as a technology.
