I would seriouusly avoid the Spin and Go
You have earnt $10 playing freerolls so don't waste any $$ on a gamble.
I started playing just freerolls, and now have healthy BR's on 3 sites. I would play the $0.25 Mtt's and move up to $0.50 when you hit the $20 mark. With you being able to play on PS the fishies (world) are at your feet
I would not go anywhere near 2nl with a $10, wait till you have at least $40 if you wiah to play cash game, I personally prefer Stt's/Mtt's to cash games, but that's me For Mtt's I would use the 40x BI rule of if you want to be a BI nit like me then go for the 100x BI rule.
