I usually re-invest it back into mtt's until the credit is used up and I have to deposit again to be able to continue my hobby
So I am not yet a profitable player and can therefore unfortunately not yet report anything about what you do with your winnings
At times, though, I've been able to make reasonable gains. Now it's about achieving a higher level of regularity for me and expanding my skills accordingly, since I'm having a lot of fun with this game, it luckely doesn't feel like learning to study it.
