If you've played 1/1 at the casino I wouldn't suggest playing the same stake online indeed, altho starting out at 0.01/0.02 isn't the best idea either.
I'd suggest starting out at 0.10/0.25 or 0.25/0.50, depending on your BR.
0.01/0.02 can be really profitable, but you'll ONLY be playing complete fish, personally I prefer some regs at the table.
Also I recommend playing 6 handed, especially in the micros, all the regulars are playing below 10/10 (vpip/pfr) 9 handed, and it's a terrible grind.
Especially considering you don't have any online experience, and you have to start 1 table at a time.
Also, definetly read up crushing the microstakes, and maybe harrington on cash.
Good luck!
