You know, it depends from you, i mean what you want. Playing cash games you don't have a particular schedule, you can stand up when you want. On the other side cash games have smaller dispersion, so i mean in mtts you can have minus 3-4 months(I don't the expert in mtts,its only my thoughts), but playing cash games you can have stable winrate and profit(playing cash games you also can have losses 3-4 month
it depends from you).
When I started playing I began from reg cash tables, then played 6 and 9-max sng's, then I find myself in zoom,fast or rush(whatever you want
) tables, and still playing them.
So I mean you should find yourself playing different types and when you finally find it just crushing them!
Good luck on your way!
