Risk: Moderate

Starting an online course reviewing side hustle from scratch can be risky, especially if one can't afford to lose money. Potential losses include both time and money invested in creating content, building an audience, and marketing the reviews. Beginners may spend money on equipment, software, or advertising without seeing immediate returns. While there may not be high startup costs, the time investment can be significant before turning a profit, typically taking 2 weeks to a few months. Online discussions mention instances where individuals failed to attract an audience or monetize their reviews effectively, resulting in lost time and resources.
