Moving up or out?

Being a newbie, I had a quick question about expanding when the time comes to either to a higher limit or starting to play two tables at once. I imagine most people would recommend just going to a higher limit, but I thought maybe gaining experience mulit-tabling would actually be more beneficial in the long run...? I know multi tabling is a more risky approach, the major downside I think would be that it magnifies my weaknesses. Any advice on this matter would be greatly appreicated! I would also love to know people's personal experiences about moving up a notch!
Currently playing .10/.20 Fixed limit
Bankroll 50$- chump change I know, but ya gotta start somewhere!

Thanks,

Seriously, nobody single tables anymore except for the fish. Why do you think that is?

Multi-tabling is better than moving up.
You'll get put in the same spots time and time again, meaning you'll be able to learn what to do much quicker. If you're worried about loosing more my MTing, then move down stakes until you're a winning player. Once you're winning add tables. ~4 tables should give you a lot of time on each.
Move down stakes as I don't think your BR is big enough, but I dont play FL so im not sure on that. certainly for NLHE your BR is only 2NL worthy.

Once you are beating that level easily and you're rolled for the next level, its time to move up.
