Quote from Ghost of Cutten:
Depends mainly on your win rate.
High win rate (70%+) - bet 2-4%
Medium win rate (50%) - bet 1-2%
Lower win rate (30%) - bet 0.5-1%
Lottery ticket trade (e.g. 20% win rate) - bet 0.25%
1) Why would you bet when below 50%??? go to a roulette "near you" instead... (and get 49%, YAY !..)
2) You forgot to mention loss/win ratios... without which the win rate is completely meaningless...
Acrary post is the best post so far.
