Trying to think of other Mitch jokes that might work...

I have a wallet , it's got a bitcoin in it that floats to the top. So if ever the world economy crashes and burns, I will reach for a bitcoin . I'm saved by the buoyancy of freedom money .

Or perhaps...

Sometimes, I like to take my cash and throw it into bitcoin and say HEY MAN YOU'RE HOME.

Probably lame but there's gotta be some good ones in there somewhere.
