Excellent Video explanation Luke.
One of the biggest obstacles in convincing humans to join Steemit is convincing them how to turn their SBD into cash if they want. Like you said, they have faith in the dollar. So they stick to it.

When it comes to survival who do you think is going to win, a guy with a gold coin, or a guy with a gun? No one is really worried about survival right now but there could come a day..
Thanks for sharing your knowledge.
