Two reasons you should not short Bitcoin.

1) Actual legitimate Bitcoin payments are increasing and real.

2) Even if this whole thing does collapse, never short something like Bitcoin unless you have unlimited cash to support such a short. Even if you're right, can you continue to sustain your short if the peak is $100,000 a coin before the collapse? (And the new bottom is $10,000, still higher than right now)

If the price goes there, can you afford the short?

There's a dead comment that says this:

>* Traders will devise a suitable risk management plan prior to initiating a short position. Unlike the media driven nonsense about a large activist shorting a bull market permanently, many traders can and do make leveraged long and short trades all the time, with the intention of exiting at a loss if the trade doesn’t go immediately (for some definition of immediately) in their favor. *

In my experience working at prop firm that was trading (speculating) on futures, this is the case. We would enter leveraged short/long positions based on some kind of signals with some kind of risk framework for all assets in the portfolio.

What about a put instead of a short? There aren't any options markets yet, but that might be interesting.

Also a smart shorter will always put in a stop loss price, but stop losses can slide because cryptocurrencies move fast.

I can't find any decent options market. Do you know one?

If I did I wouldn't have said what I said...

How can a single coin attain $100,000 ?

By someone being willing to spend $100k to obtain one.

I’ve been watching bitcoin since sub-$1 prices. A further 10x increase at some point is not so crazy.
