I get a chuckle when someone who read an article about how bad Bitcoin is confidently tells me I'm wrong and tries to argue with me (I don't do this anymore. I just wish them well.)
I've spent literally thousands of hours studying various Bitcoin and Bitcoin related topics. Maybe I have a couple things to teach to people who want to learn. This is true of many people in the Bitcoin space. Many of us are eager to teach.
I always take the opportunity to learn from others, but I'm not going to argue with anyone who approaches me in a condescending manner.
