As a beginner i wouldn't deposit much, cause less money you have in your bankroll is less you itchy to try higher limits out. And believe me if you ever do so, sharks over there will chew you and spit you out with no money in a pocket in no time. So better start small as possible, stick to the bankroll management and try build it up.
I know that it seems silly and boring sometimes to play for cents or playing freerolls, like you were wasting your time. And i know you can't wait to play bigger games.
But think about one thing - on a higher limits are more experienced opponents and harder to win, especially with just few experience playing poker and if you are loosing you loose it much quicker there. So it's smarter to start it slowly and safe, collecting some experience before you jump into shark tanks.
On other hand advantage of small amount of first deposit is that your bonus will be chopped on smaller chunks, which costs less amounts of rake to reach. So you get more of your 30$ first deposit bonus, while playing micro limits, as if you have made 100$ deposit, if you know what i mean.
p.s. You should learn that poker does never excuse the haste, neither at making decisions at table nor while handle with your bankroll and deciding your bankroll management plan.
p.p.s. And the last tip to you, take your game serious, educate yourself, analyze your questionable
hands and try to find the way playing it better. Even highrollers with years of experience keep doing that! You might also try out some software that could help you in that like PokerTracker, Flopzilla, ICM Trainer, Equilab, PioViewer or similar products, to bring your poker education and skills on a higher level. Don't forget there are some great books written about poker too.
