How to buy Bitcoin with 5$?

Could you please elaborate on the steps involved in purchasing Bitcoin with a limited budget of $5? Given the current market conditions and various platforms available, I'm curious about the feasibility and practicality of such a small investment. Could you provide a step-by-step guide, outlining the necessary accounts to create, verification processes, and potential transaction fees that might be incurred? Additionally, are there any specific platforms or wallets that cater specifically to small investors like myself? I'm interested in learning about the risks associated with such a small investment and how to mitigate them effectively.
