And sorry, I know I should but I can't just let this go. You keep comparing Bitcoin to cash, as if cash is the solution to the unbanking problem we are talking about. You say this about Bitcoin vs. cash:

“Harder to use, costs more, still less secure than cash!”

None of those are absolutely true. For a local transaction in small amounts, yes, cash is easier and cheaper. For large transactions or for transactions with someone who is geographically far away, cash loses on all three of those, big time. I don't even need to explain why do I?
