Freeroll or not
The best thing with freerolls is that you will never feel the pain of losing money.
If you are playing to make money, it is not the fastest lane. But if you play to have fun, it is risk free. And you totally can create yourself a bankroll with freerolls. Just manage your subsequent money as if it was important money, not freeroll money. you should be fine. Then again, if you lose it all, who cares. Try again.
