Related to this, does anyone know of a way to bet against bitcoin (or cryptocurrencies in general), without buying cryptocurrencies themselves?
There are lots of more-or-less sketchy cryptocurrency exchanges which allow you to shortsell bitcoin, but these all require buying cryptocurrency in the first place as collateral.
The upshot is that if you bet against bitcoin and win, you win a bunch of... bitcoin. Not so useful if you want to bet on a big collapse of crypto in general.
Selling bitcoin futures seems like a way to bet against bitcoin in the long term, using actual USD, although I don't think that will ever be an option for smalltime investors / individuals.
