If you can create a trading bot of your own, then obviously the bot is better because it's just you without the emotions part which is good for trading but If you hire it from someone especially in crypto space I have seen these things ending in just scams and nothing else, these are unaudited bots and often face script errors after some point which means you are facing a great risk on your money, also chances are these bots won't be able to compete against bots of big institutional investors. So in this case you as an individual are much better than a bot
