Are there differences between the regular martingale and grand martingale strategies?

[Julio88]

The main difference between regular martingale and grand martingale is the amount of money wagered. In regular martingale, the bettor increases the bet amount after a loss but keeps the amount the same after a win. In grand martingale, the bettor increases the bet amount after both a win and a loss. This strategy is riskier than regular martingale and can lead to large losses if a losing streak occurs.
