You can trade contracts for difference (CFDs) on Bitcoin with 1:10 leverage, including shorting them, at places like Plus500

Great way of taking the risk created with the volatility of Bitcoin and multiplying up the risk massively so you can lose money even faster...

How are those contracts validated and enforced on sites like that? The SEC used to watch naked shorts relatively closely before 2008 and it's been banned since then; but how is that arranged in practice with a currency whose primary selling point is its anonymity?

I know I'm risk averse, but even still this seems like the basest insanity to me.
