Bankroll.....
Compa61 This is purely my opinion and one not supported by many of my friends on this and other forums--I do not play progressions. I play each spin just as the former spin. This is an individual choice on my part; I am not criticizing anyone who does use a progression. So, to answer your question the best I can..... I play 12 or 13 units (a unit may be any amount) each spin. I don't vary until I have increased my bankroll by a comfortable margin. Then I go up and stay there until I'm again comfortably ahead. I call it plateau betting, but I think some author used the phrase before I did. You just move from one comfortable plateau to a higher one. Sam

ok, i see. Another Q, How would you be playing with only 50€? Thanks /compa

Assuming you are saying 50 Euro............. I would find a casino like Bet365 that allows very small bets and start there. I think you can bet 1/4 euro. I don't know what dublin uses, perhaps the pound. Anyway, you can bet 1/4 of whatever they use. I bet single American dollars. 50 Euro or 50 pounds or 50 dollars is much to small to play with whole units. I usually start a system witn $1000 U.S. Sam
