1) yes it's possible to do it. And possible to go big if you're good, young and dedicate yourself

2) you haven't done much research because there are many sites offering better freerolls with no raked hands requirement

3) play NL your risk of ruin is less (when I started out I played ultratight AA, KK, QQ, JJ (though JJ is played a bit more passively preflop unless the flop came all unders then I'd jam it). Then jam the flop if you have an overpair. This strategy works well at $100 NL buyin and below it looks like a bluff to them all the time. Never slow play at this level

4) when you build a bigger roll (which will probably still be small) you play tight and make a BIG raise with AA, KK, QQ don't get tricky. Maybe allin even, you'll be surprised by how many times you'll get called by JTs, 22, Ax etc.

5) many here started out with very little, if you're good you can do it but if you'd accelerate much faster if you actually did deposit money

Regardless good luck.
