/**
 GenWealth AI is the latest in AI, Machine Learning, and Large Language Model based investing. The taxes from the project will be used to create the GenWealth AI platform.
 This project is going to be driven by an AI model that will ensure maximum profit, Machine Learning will be used to continuously improve the model so that it becomes more
 and more efficient, and the Large Language Model will be used to gather information on what the latest launches are and the likely profitability to ensure we continue to
 go. Eventually, we intend to launch the web-based platform so that you can "stake" your genWealth tokens to continue earning based on the profit we generate.
