First item. No, bitcoin is not a joke at 7x/sec. Why? Because really, it's about 3/sec and with that lame number, bitcoin is about the 20th largest currency (check M1 numbers) in the world.
You do realize you want me to compare a max number of transactions per second with a money supply (M1) ?
Well, maybe that is a joke. It's actually rather funny, isn't it? Or maybe the OTHER FIAT currencies are the joke. What do you think? Must be something going on right there.
Nah, at least with most fiat I know what I can pay for the next year and I can actually pay somebody when I want and with less costs.
