What is the best grid bot trading pair?

I'm curious to know, what do you consider to be the optimal trading pair for a grid bot strategy? Is there a specific pairing that has historically proven to be more profitable or stable than others? Are there any factors I should consider when selecting a trading pair for my grid bot, such as market volatility, liquidity, or trading volume? I'm eager to learn more about how to maximize the potential of my grid bot trading strategy.
