Bankroll-management (BRM) is very important at poker. I am not a cash player, but AFAIK:
- you should generally get max buyin at the table
- you should have like 25 max buyins so in a bad beat you don't lose too much
Generally the max buyin is 100 big blinds (BBs) so you need 2500 BBs.
So 0.05/0.10, max buyin is 10 (100*0.1BB=10) so 300 chips is 30x the max buyin. Looks good to me!
BTW, BRM is mostly meant for winning players so you can handle bad beats and the variance. If you are just beginning, not expecting a profit and just want to have some exciting fun, you could play higher stakes than that. If you want to take it seriously and be profitable, you should stick to some proper BRM
