One of the problems is, that most of the sites won't pay you anything, unless you have made an actual deposit.
This is an excellent point. Luckily for me, I don't plan to ever withdraw, not even if I run my freeroll winnings up to a million dollars. I dont play poker for money (for profit), but obviously to play with the best poker players you need a sizeable bankroll, so that's why I use
real money, but it has nothing to do with greed.
But for those who wish to take this route to fame (lol) and fortune (double lol), franken's point is something to make note of. You CAN make withdraws even if you have never deposited, but the
poker site typically will only allow you to withdraw as much as you've paid in rake to them over the years.
We might be playing for "free", but we still pay rake... (I call us freerollers "Rake Machines" and it is super smart for
poker sites to run freerolls and create more of us)... so eventually you'll be able to withdraw at least some of your funds if you wish, but due to this problem you probably will never be able to withdraw "life changing money". For instance, let's say I do run my bankroll into the 6-digits, there's no way I'd ever be able to rake an equivalent amount, so that money is basically "owned" by the poker site, not by me even tho it's "my" funds.
So again - excellent point to keep in mind for anyone planning to go this route and hoping to make a living off it. Perhaps you should check the rules with the poker site you are playing on to see what method they use to determine how much you can take off the site, and how often you can do it.
