Play the smallest stakes possible while learning the game. Move up after your bankroll allows it OR after you're a proven winner at the stake you're playing and have the money to deposit. If you're a losing player at the lowest stakes spend about half to 80% of your poker time studying.
Just play what you enjoy. Tournaments are arguably more beginner-friendly. Cash games have less variance.
Depending on your game and stakes the required roll is going to vary. Just google bankroll management for the game you're planning to play and stick to that. Don't worry about going broke a few times while learning though. I had to reload twice as a total beginner before becoming a winning player and building my bankroll.
Bankroll amount depends on how much you can afford. Try the different games to see what you are best at, or what you enjoy most. You can't expect to make money at 1st, it takes practice to become a winning player.
At the beginning of the journey, you should not spend your money on expensive tournaments-after all, you are a beginner and can easily make a lot of mistakes.Play-and you will choose the appropriate discipline in the future yourself in order to earn money on poker.
The best option is to build a bankroll by playing in freerolls. Thanks to this you will gain new knowledge, experience and will be able to improve your skills without risking your own money. Set a goal and try to build a bankroll of at least $ 100. Good luck.
Start at a 1c/2c ring game so you can come and go as you please. Some people do not like low stakes , so they will move up to 2c/4c poker or .05c/.10c poker as they feel there is more danger of losing, so people enjoy the game more instead of things feeling like play money games.
If you are serious about online poker but also new to the game, then 100$ is a reasonable amount of money to deposit. The reason is, it gives you a reasonable shot at not having to deposit again, if you quickly become a winning player and follow good bankroll management. 100$ will give you 50 times the full buyin for 2NL cash games, 67 times the buyin for 1,5$ SnGs and 100 buyins for 1$ MTTs. Those are reasonable numbers to work with, and these are the limits, you should start with, until you have gained experience and build a track record.
As for which format, thats totally up to you. The best advice is really to try them all and then pick the one, you enjoy most. Because if you dont enjoy playing, its not going to be a success. That also goes for variations like 6-max vs. full ring, Zoom if you choose cash games, and maybe even try some alternative games like PLO. At some point its best to specialise, but in the beginning you need to try different games out to find your path. Ideally not from session to session, but maybe give each game format a week or month, and then try something new.
I've been playing poker for about 5 years, and in that time I haven't spent more than $ 100 on the game. However, thanks to freerolls, I was able to build a bankroll of more than $ 500 in less than a year. So the bottom line is, you don't need to invest in a game if you want to build a bankroll. All you need to do is play the freerolls available to you every day.
Ok, so free rolls to build up bankroll then tourneys ands sngs. Now I feel that you get more loose players in low stakes games like donkeys calling damn near everything. But in higher stakes games people play better poker but my bankroll is too small for those games.
Oh it's a hard one. Something tiny like 5$ just won't do the job because there are no stakes that small that you can play for 1% of your bankroll. On the other hand putting in 50$ - 100$ is risky and I woudn't want waste a hundread bucks being a new player. So... frerolls are the solution
