9000 sats for a dollar?

That is wishful thinking.
I believe we will see 1:1 parity with the dollar.

Meaning your typical faucet is giving out dollars every time you click.

I too see something like this. And it will be that everything else is measured in sats.
So, it will be 15 micro-sats of litecoin for a coffee or some such. And the swapping network will just work it out. Whatever you have you send, whatever they want they receive.
