My biggest fear isn't losing money, but the moment when the liquidation text message pops up and I realize I was just "thinking I had time." When the red line of borrowing and lending is three steps away from me, I usually do one very cowardly but useful thing first: look at the collateral and debt separately, don't mix them up with fantasies, add a little if I can make up for it, if not, pay back a small part first to pull the line apart, even if it costs some fees, it's better than being wiped out all at once. Then, stop pledging and sharing security for those that seem to have good returns, like a "nesting doll," because when volatility hits, it won't help you resist; it will only make it harder to exit. Finally, accept your fate and set a hard stop-loss or liquidation withdrawal point—don't rely on quick reflexes and luck anymore... I'm also practicing.
