If u can learn to mass multi table, put in good volume eg 100k+ hands per month and beat 100nl.
100k hands a month? I barely know anyone who plays 100,000 hands a month (outside of rush/zoom), i'm not very good at multi-tabling and play live 3 nights a week (so prolly have similar time if not more time than steve for online) and I struggle 30,000 a month on my good months..
Also, beating 100nl, I bet
at least 35 of the top 50 in the world on pocket 5's couldn't beat 100nl if they started at it tomorrow.
I'm not saying this is the best thing for op to do. OP was talking about guaranteeing a decent additional income and being able to put in the hours that are necessary. So playing online cash is the best way to do this imo. But of course games arent easy etcetc. Most likely op has a better chance of making $$ playing online mtts/ live cash and will probably have more fun too.
If you are competent at multitabling and play for a living then 100k hands per month isnt really a ridic amount for ssnl. Dave you play high stakes PLO so cant rly compare the volume you put in to ssnl grinders.
