As the friend said above, many sites have freerolls, and deposit bonuses. You can take advantage of partypoker, for example, which gives you $ 30 bonus on your first deposit. Or at pokerstars.es that gives you $ 20.
You must be maximum cerful at the begining for understud what type of poker game easy for you. I mean SNG or maybe MTT. For begin I think most important SNG (not turbo). And ofcourse bankroll managment is the main thing!
There are many ways, the bonuses for registration, free tickets, the freeroll they give daily and every week, there are many ways to do your banking in poker.
There is a good amount of freerolls to play. Once you won some money from there you can play more frequent and get better and eventually become a consistent winner.
Also if (when) you win something in a freeroll, don't go straight to the cash tables but build up a bit first from the freerolls so you have some backup when playing for real money
You need i high skill level and luck. It's hard, but possible. If you had this skill level i talked about, i would give you the advice to make a deposit. The result will may be the same. The difference will be, that you don't waste a lot of time. What is your intention? If there is a honest intention to build up a reasonable bankroll, you wouldn't try to "make a free bankroll".
It is possible for sure, but you need a lot of luck. Because Freerolls are usually like Jeopardy!
I built a bankroll through many different Freerolls - especially PokerStars School, some of their tournaments are real money payouts others are in Tournament dollars which were easily turned into real money on Fifty50 SnGs.
Obviously, the best way to create a bankroll is to freerolls. Pay attention to the 888, there are a lot of daily freerolls and good conditions for new players.
There are a few sites that give some no deposit poker rewards for new members (but depends on your country), after that you'll have to play a lot of freerolls to build your bankroll(888 Poker has so many freerolls and you also have the daily wheel to try your luck). While you build your bankroll you should try to find a few sites to read articles about strategies, read some poker books, maybe find a poker player that streams on Twitch...
Aren't we all here for the freerolls ? I doubt many people here would say otherwise. If we had thousands in disposable income to blow on poker we wouldn't be here.
No doubt Cardschat offers some of the best freerolls, with less people entered and more serious players.
