I started with a $10 BR on Pokerstars
a few months ago. Played 1c/2c and have built it up to $127 currently. Along the way I played a few $1.50 and .50c SNGS.
So you CAN build it if you play correctly at those levels.
I've taken the occasional stab at 25c/50c limit and had to drop back down 1c/2c. So since then I'm playing strictly at bankroll recommendations.
Once I get it up to $150 or $160 I'll move up to 2c/4cNL.
Buy in for 0.80c at 1c/2cNL and don't look back... just keep going until you get up to about 20 or 30 bucks and then try a few .50c SNGS to help boost it... but keep your eye on the prize. Reaching $150 to move up a level.
