I'd stick to the single table DOLLAR games until you break $25...at least
I had the same thread/question a little more than a week ago about my small amount at America's Cardroom and I was lucky to triple the amount right away, but I lost one-third of it again trying to play higher-priced games a bit too soon.
I now intend to sticking to $1-3 games and
freerolls until I at least break $80-$100...
...and when I say higher-priced games from there nothing higher than $5 until the next milestone I set myself for, and grind grind grind
Keep it low and just be patient....that's the key
