If someone is not open to learning about bitcoin, I find that this is a lot of the time due to pride. Or another reason is they are old and when they were young they bought a house with 6 months of savings, so they are complacent to the system that worked for them. Being too prideful or complacent to accept alternative beliefs is one of the worst financial positions you can make. When NGU it gives me great joy to think of these people slowly watching Bitcoin take the monetary premium they think so highly of.
