90% return of 100000 ped cycled is losing 10000ped of your bankroll. If you had 10000 ped on your card, you:
* still had 90% return on your activities
* your roi on your money is -100% and hit risk of ruin
* you were stupid for tting everything and not getting markup to hedge against the in-game rake.
Please guys.. stop and read what risk of ruin is and if you want to get into a little deeper math, learn the mathematics behind proper wagers with respect to bank roll and playing games with an edge (ie. Card counting). It will help you understand.
Also, 90% is not true. It is based on the idea that planet partners get 10% of all your activities.. that is a very steep rake. They get a portion of decay, not loot. Big difference. We also must include that some tt loss is kicked back in skill gains. So by playing, you are buying your skills at no markup. See my log for details.
