Just recently got into poker and am absolutely loving all the strategy that goes into the game. I recently dipped my toes into absolute micro-stakes 0.1/0.2 cent. This is where I want to try out strategies and my question is how much of a bankroll should I put into my account to start playing at these stakes? A general rule of thumb would be great if there is one for the bankroll you should start at different stakes with. Thanks

100 buy-ins for every limit is the conservative approach but you can do 50 w/o much of a risk of ruin
move up when you feel ready, play a few days, if you don't feel comfortable with the money swings or with the way you're playing, move back down a limit. Keep taking shots when it feels right.
gl to you.

Thanks I'll give it a go

Woah 100 buy-ins? Maybe for sit-n-gos. I think 40/50 are more than enough if you're comfortably beating a level, 20/30 is as riskier as you could go.
If you aren't beating the level the bankroll doesn't matter at all I guess.

When you're a beginner, I don't think you really need to think of "bankroll management" as such, as it's not as if you're paying your rent with poker income, so you don't need to always have a "roll" stacked with buyins that enable you to keep playing. What you have as a beginner is a "training budget". Just deposit an amount that will be enough to give you a few weeks of play, even if you lose it all. Once you're beating the game, then you can consider what kind of roll you think you'll need before taking shots at moving up.
FWIW, when I first deposited years ago and played 2NL, I started with $32, and I never went busto. A beginner might lose 15 BI in 15,000 hands or less in today's games, but it will still take a newbie a decent amount of time to play that many hands. By the time you've done 15k hands, (hopefully without going broke), you'll know whether you want to take poker a bit more seriously. For now, I'd suggest just depositing a small amount and see if you have fun.

newbie -> 20 buyins for stakes you can afford to lose at

this is good advice
