“True” Bankroll and “Risk Capital”

Whenever we talk about percentages of bankroll, most casual bettors feel that they are on the “high end” of the ranges we discuss. This might SEEM true – but only because the “true bankroll” for most casual bettors is higher than what they have in their accounts. That is, many bettors might have $X in their accounts, but are willing to add another $Y if they draw down their account. Professionals normally already know their “full bankroll” and need to preserve their “capital” versus “risk of ruin.”
