"Easiest" Microstakes MTT

I've put 21 USD onto my account, ready to play micors... but which? I thought that
0.55-1.10USD ones might be the safest desition for me.
Thanks for any tips.

That is probably a good start. You should also look for MTT's that have less players. Knock out tourneys are good because you get money for knocking players out, so even if you bust out before the money, maybe you have KO'd a couple players.

With 21 dollars you want to play the lowest stakes, and the smaller tournaments. If you play the BIG 1.10, cahnces are you'll lose it all. Of cours if you are fine with depositing more, you might go for it. If you can afford to lose 200 dollars, going for the huge MTTS might pay off, if you get lucky suddenly you have hundreds of dollars in bankroll
