I invested 0.1BTC in BetKing, during the presale. I also chose to have Dean sell my Bitcoin Cash and IIRC Byteball for a larger investment into Betking. I ended with 6208.6 BKB.
The buyback price is currently $0.0969, but I can only sell 10% of my tokens every week at that price. Using the current preev.com rate, 1 BKB is equal to 0.00001090BTC. My 0.1BTC investment (equal to a bit over 0.11BTC after BCH and Byteball) is now worth 0.067BTC, or a 33% loss. That's assuming I waited to sell though, as it would take many weeks. Not sure how much your moneypot investment was, but I'd wager that it's around a 33% loss.
If I wanted to cashout right now though, I'd have to sell at HitBTC, where 1 BKB is going for 0.000006BTC, so my ~0.11BTC investment is worth 0.037BTC at market prices. As bad as your MP investment was, I don't think you'd be down over 60%. But then again, they are holding your funds so idk. I'd say you're investment in BetKing would be about equivalent to MoneyPot losses, though with potential to grow if BTC price goes down or stays similar with BetKing tokens. On the other hand though, you might have debt tokens and eventually be repaid some of your losses with MP.
Strange enough I think after a little retraction, online betting is coming back.. I do not know where I get this impression.
