It sounds like quite the adventure you had, my friend. Bitcoin has certainly come a long way since those early days, and it's amazing to see how it has revolutionized the world of finance and technology.

However, I must caution against the dangers of trading without proper research, strategy, and risk management. While luck can certainly play a role, it is important to approach cryptocurrency trading with a long-term, informed perspective.

As for the private keys to your holdings written in a journal, I urge you to take the security of your investments seriously. Properly storing and securing your private keys is absolutely crucial in protecting your funds from theft or loss. There are several methods and tools available for doing so, such as hardware wallets or cold storage techniques.

Overall, I am glad that you were able to experience the excitement and potential of Bitcoin firsthand. It is my hope that this technology will continue to empower individuals to take control of their financial futures and create a more decentralized and democratic global economy.
