Build me a simple Telegram bot for a fun money game where people can add virtual funds, keep track of their balance, and invest it to try to grow it over time.

I want it to feel like a casual mini finance bot, with basic commands for starting the bot, checking balance, depositing, and investing. Users should be able to see clear messages about what happened after each action, and the bot should save their data so the balance does not reset every time. Make the flow easy to understand for normal users and keep the interface clean and friendly.

If anything is unclear, use sensible defaults and look up current docs online if you need to. Please make the whole thing work in one pass, with the main bot logic in the Python file and any setup instructions in the README.
