It is indeed probable that some are using these mortgages on the new Futures market (or other means) to short Bitcoin. IANAFiduciary - I think going short and long have equal risk. The most easily defensible position is to have thrown a small amount of spare cash into several coins a month or more ago, and watch the roller coaster.

At this point, the market's too hot - there's too much going on. And Bitcoin itself isn't seeing the meteoric growth today that it has over the past 2 weeks - where is the growth from the Futures exchange?

Sure.

You will go broke first when the price first doubles.

Then them will go broke when the price crashes.

This is possibly the worst financial advice in existence.

Are there sane ways of shorting Bitcoin?
