I am a little bit confused by this assertion.  I believe that I understand the setting up as low leverage that allows more BTC price movement before your would be forced out of the position; however, I am a little confused how longs would be unprofitable, currently with the recent price move up.

I am supposing that you entered your long and your short at BTC prices that were decently higher than today, such as in the $8,200 or higher arenas?

But if you had entered both a long and a short, yesterday-ish, at the time that criptix was asserting his bearishness, in the $7,600 price arena, then the long would be doing much better than the short, currently... right?   and if you enter with decently low leverage, then perhaps you could rest assured that you would not get liquidated out of your short position until $10k plus.. but at the same time, if BTC prices start to get close to $9k, you might want to manually close out of that short position rather than losing more and more as the BTC price might have decent chances to get close to forcing you to close your position.  

So, it seems that your perspective on strategy is going to be influenced quite decently by when you entered the position, you are likely going to have to spend a decent amount of time watching the market and even trying to assign odds to various BTC price directions on an ongoing basis in order to figure out whether the odds would be in your favor to close a losing position early or to re-establish your bets to figure out if your trading stash is growing or shrinking.

I do appreciate your stated approach, d_eddie, in which you are setting aside some of your profits from time to time (taking them off the table), but still I would imagine that sometimes there is going to be shrinkage of the trading stash and even internal questioning about whether the size of the trading stash is enough (temptations to get greedy by redeploying profits into the trading stash that previously had been stashed away).
