How much does an AI bot cost?

I'm curious to know, how much does it typically cost to acquire or develop an AI bot for use in cryptocurrency trading or financial analysis? Are there different factors that can affect the price, such as the complexity of the bot's algorithms or the specific functionalities it's designed to perform? Additionally, is there a significant difference in cost between purchasing a pre-built bot and commissioning the development of a customized one? Understanding the financial implications of these options would help me make an informed decision on which route to take.
