A pittance relative to it's utility for bad actors. I like Bitcoin, and I cheered it on as a pimply-faced nerd who wanted to watch numbers do funny tricks. It's protocol is incompatible with what society deems acceptable though, so something's gotta change before the world goes all-in.
No fiat will ever be perfectly solvent, but that's a poor excuse to argue for the superiority of a currency as fickle as Bitcoin.
