The honest answer is yes. Pretty much all progressive betting strategies can be seen as risky. If you’re on a streak of bad luck and continue losing bet after bet, you may find yourself with no money left as the wagering will keep progressing with every lost bet. But! The Paroli system is less risky than the Martingale system where the progression is steeper. The Paroli system makes you stop after 3 consecutive wins to ensure that the losses won’t be too big.
