If you want really profit, 100 bits starting bet, 5x onloss 25% it should be safe enough to make small profit in short run...
but if you really wanna profit, you must learn poker, more profitable than dice.
Dice is for the lazy.
Are there any online tutorials for poker? What site would you suggest me to play on?
Well, SWC poker is where I would let you play
http://swcpoker.eu/For the tutorials you need much practise.
I can do a minitutorial for you.
I would consider Omaha, which is 4 cards dealt in your hand, and you must pick the 2 best that works with the 5 on the board.
Best hand you should almost glorify are AA KK QQ JJ.
Hands that are mh: 1010 99 88 77
Lower hands are just risky.
Thats the basic for being the most tighest man in the world.
But in omaha is more elastic as a thing, because anything can happen and make you win with the strangest hands.
If you want a fast and practical tutor of poker, PM me I'll teach you via skype anything you will need
Edit: I setted it as simple as possible, but i will explain you better via skype how to decide if a hand is good to go or to trash it right as you see it
