That is what happens when you get greedy. Have to play more conservative and know when to quit. I lost some bitcoins getting greedy.
Happened with me too today but I realized it's not my day and stopped. Winning & Losing, both part of gambling you win today you might not win tomorrow. Never chase losses and you'll be fine.
Sorry for your loss OP. Hope you feel better.
That's how I lost, I once chanced losses and only ended up losing more. The other time I got greedy and tried to get more when I should have cashed out.
