My trading journey is spanning to almost 2 decades now, and if I remember clearly, it was between 2004 and 2005 that I started trading. I can't confidently call the exact year for the fact that I first started gathering trading materials without acting on them before I later started reading and training on what I read.

As you can see, this was years before Bitcoin was even born and I can confidently say that the price of Bitcoin was still Zero ($0) when I started trading. But it took me years after Bitcoin was born to actually open my first trade on it and the reason is because I am already trading other aspects of the financial market.
