Who sold at the bottom?
d_eddie because of "trading with a hedge"?

Well, I've just sold something on the way up. Actually closed the short before loss (really tiny profit) and reopened it higher, a little larger. If she keeps going up, I will close it in loss when the long is near or above parity. As long as the long is larger I'm OK. If she gets back down, I'll cash out half of the short and play a little wait and see.
sounds like plan. i guess your system is much nondeterministic.
Uh ehm, the system saw the light after a... uh... how can I explain... a dream where I saw mammoths in the charts, stampeding on us poor hodlers. It was around the time when most of us agreed we were in bear territory, long before we started talking about capitulation, which became the rage only later. I opened a short, staking most of my play money (which current me, more seasoned and detached, wouldn't do). I cashed it out a little at a time, reconstructing it at every bounce. I doubled my play money (100% btc, no fiat) in a few months, like 4-6. So the system is solidly rooted in pure SOMA practice.
It does require work and planning ahead - planning for both directions! I try to make my plans on a cool head, with no positions open, and mostly stick to them, with occasional tweaks inspired by sentiment, whim, suggestions and of course fresh SOMA results.
great! it sounds like a not so easy system for real pros. but what the hell do you mean with SOMA. I just asked before but probably you didn't read it.
