Are bots safe to use for multi-exchange arbitrage?

I see trading bots advertise for multi-exchange arbitrage, where they try to profit from price differences between exchanges. And I want to know if letting a bot do all of this for you safe or at least reasonable at all?

In theory, the bot scans prices on different platforms, buys low on one, sells high on another, and repeats as fast as possible. Speed is the point of these bots.

But what about everything else? Things like transfer delays, liquidity drops, or the bot just glitching? Couldn’t it turn a “safe” spread into a loss?

Anw I can see the point of them, asking this because of the Banana Gun Pro bot, a higher-tier one that they’ve released. Tempted to try it but I can also see that even with automation nothing is guaranteed. So would you trust a bot with multi-exchange?
