Betting units
Can someone please explain me the reasoning behind betting different amount of units per bet? Lets say you bet from 1 to 3 units based on your confidence level. 1 is least confident, 3 is most, and 2 is somewhere in the middle. Wouldn't you make more money in the end if you make all your bets a 3-unit bet, regardless of how confident you are? If you're a winner in the long-term, then all your bets (1-unit, 2-unit, etc) should make you money. Betting less just because you have a 53% chance of winning instead of 58%, won't make you more money as far as I understand. So why do this?
