Gambler’s Ruin
Gambler's Ruin is a mathematical concept in probability theory describing the certainty that a player with finite capital, playing a game with negative or zero expected value, will eventually lose all their funds if they play for long enough. In the context of options trading and cryptocurrency, this principle explains why traders using high leverage or improper position sizing face inevitable bankruptcy, regardless of their individual win rate.
Even if a trading strategy has a positive edge, if the position sizing relative to total capital is too aggressive, a sequence of unfavorable market moves can wipe out the account before the edge can manifest. It serves as a fundamental warning against over-leveraging in volatile markets.
Understanding this concept is crucial for risk management, as it dictates that survival is the primary objective in any trading environment. Traders must balance their risk per trade against their total bankroll to ensure they do not hit zero before their statistical advantage plays out.
