Sorry mate, I hope you didn't lose such a huge amount of money. I suppose that you wanted to go really big and gambled everything "on one card". Maybe if you won you would have lost it again by repositioning it (or not, but I would consolate with that).

Nobody teaches someone else's head, but I hope your experience serves other members so they don't fall in the same mistake as yours. Leveraging is gambling, and you can win a few times but if you keep gambling indefinitely you always lose.
