I haven't used any trading bot personally, but from what I'm hearing from those who did use them I can say that it usually doesn't work as good or even works terrible at time if you 're trading amount is small, but if you're trading with around $100k or more you can make some money out of it since with a good strategy you can make the price or dump in coins/token with less liquidity and slowly sell on top/buy on bottom and rinse and repeat.

You can also trade with around $10k using front running bots on decentralized platforms like Uniswap and Pancakeswap and get around 1-5% per trade depending on how low the liquidity is and how you configure the trading bot.
