I lost in the last hours way more LTC than I should have lost based on my percentage of the bankroll (around 2.5 times as much). I'm at -61% ROI, but the bankroll didn't decrease that much. How is that possible?
It might be because there were a bunch of new large investments in the bankroll that took part in a lot of the upside and almost none of the downside. These investments are all up at least 10-15%:

And who made all those new investments, the gambler? I don't really understand what happened, it's like the gambler divested a lot, then started playing, crushing the rest of investors that stayed and now has reinvested again.
