Well a standard buyin for .01 .02 should be somewhere around $2. The rule of thumb for higher stakes is to have a br of 100 buy ins in order to handle swings.
That'd mean you should have a $200 bankroll.
With that being said, I don't think a $200 bankroll is necessary at all to start the microstakes. A comfortable roll would probably be $50 -$100 bucks in my opinion. The stakes are just too low.
You only have 10 bucks though so you are forced to play these stakes, as they are the lowest possible.
Get some practice and consider depositing more, unless you turn that $10 into some serious cash!
Good luck
