Are microstakes beatable?

[Zifadel]

I consider myself a decent player at NLHE, I usually win at my home games that I play but when I play online at .05/.1 I feel like the beginner players act so irrationally that I find it very difficult to beat them. They chase everything and always seem to hit.

Should I consider moving up a step in the limits or will it not matter at microstakes?

Am I not as good as I think I am (very possible) or are these games just very difficult to beat?

Thanks in advance
