well i can tip u what worked for me. They sugest for me start at less whit 100 buy-in's, and play sng's single table (9 person) turbo to begin, so i search there and found a nice one, is U$ 1,00 Knockout, could grind there, a litle break even, some weeks profitable, and some weeks waste at begin because i was newbie ( already am , trying to learn more and pass my knowledge on here), so i make deposits to gather 100 buy ins (U$ 100,00) and start grind, was a nice run.
But u dont need start on U$ 1,00. Have U$ 0,50 too, u need like U$ 50,00 to start, or U$ 25,00 u already can play nice whit 50 buy-in's
My advice is for u keep playing freerolls till u gather more than U$ 25,00. So u can risk grind sng's 0,50 single tables, i dont recomend mtts sngs because the variance is higher than single table. Or u can go to cash games, what u prefer, like someone said here, somes cash games u can start whit U$ 0,40.
Make the best choice for u always whit discipline, bankroll controll, much study.
And GL on tables
