Bitcoin is complex but many things in life are. Most of that complexity is hidden in good products. People are always going to be busy, but to me this is just saying that people don't see learning about money as a priority. It's like learning about air, water or food quality. If it works well enough, why dig in? But in man's foibles we pollute air and water, try to pawn off crap food, and debase currency and in each case some level of digging rises into the public consciousness. At some point people won't be able to deny that the greatest currency in the world, the mighty United States Dollar is not holding value reliably even for those who are paycheck to paycheck and at that point Bitcoin will shine. It shines now, but it'll shine then too.
