There are professional posters on this forum who make thousands a month playing online poker. They cash out regularly in order to live off the money they make online. If the site decided to give every player who cashed out a big streak of bad luck everytime they did so then these players would starve. They are still alive which leads me to the conclusion that what you are experiencing is just negative varience.

I know I sound sarcastic but I don't mean to be.
