FYI: Bitcoin’s assault on $10,000 has stirred cryptocurrency bears who see fresh evidence of a bubble. Their problem? It’s difficult and expensive to bet against a downturn.
The options to short bitcoin are mostly through unregulated exchanges, and very risky given bitcoin’s volatility. Not to mention it hasn’t exactly been a good year for bitcoin bears given the 10-fold surge in price. But for those daring enough to try, there are ways to bet against bitcoin’s rise.
