Do Grid bots make money?

I'm curious about the effectiveness of Grid bots in generating profits. Do they actually make money consistently, or are there factors that can lead to losses? I've heard they can automate trades and help take advantage of market volatility, but how reliable are they in practice? Is there a specific market condition or strategy that works best with Grid bots? And how do they compare to other automated trading systems in terms of potential returns and risk management?
