Don't Invest your own Money! It's that simple, If you don't make a deposit in the first place, there is no way you can lose your shirt. On-line Poker is a minefield of different possibilities, Crooked sites, Crooked players, even Losing Internet Connection is something that used to happen all the Time! So why invest in something with no Guaranteed Return?
I have never had to make a Deposit on any of the sites I have played on, Winning money in Freerolls and using that money to invest in Buy-in Games, Keeps me from losing my own cash, and building a small but playable Bankroll from nothing is always rewarding. Hard Work admittedly but Rome wasn't built in a day, I am now in a position that I could lose every penny from my Bankroll chasing a Dream, but I am not that Stupid! I will never be a Professional Player, nor would I want to be, but being a Hobby player I can play without the fear of losing my Money, Because it was never mine to begin with.
PKR.com went Bankrupt, and I lost my entire Bankroll over night, Did it bother me? Sure but not to a point where I felt Suicidal or anything, It was all won from Freerolls, So what had I lost? NOTHING! Because I had never risked my own cash.
