Thanks. With the tight stops tho, I found i would just have my margin closed for a small loss all the time. Never got the amounts right. Either you leave some room to handle bumps on the road up, or your margin is too tight and you're out of the game when you step away....I think the only really safe way is to be a whale who can collateralize it with just so much you can't be liquidated. I imagine there are whales on Bitmex with a few hundred BTC on the exchange who can handle sizable contracts but never risk liquidation.
