Probably bots are used by all exchanges or major players. Experienced traders know these points and adapt to trading on their favorite exchanges.
But some times you can take the advantage from the bot. I see bot already used anywhere by any traders or even exchange sites to create a crowded market.
Those traders will always put major as their favorite consider about the fact that a huge volume is the main reason for bot to be worked perfectly.
You can use it when you understand how to manage well, bot have advantages and disadvantages only those who knows how to take their edges
can bring out something good from their results, you just need to manage your strategy well.
