I lived through the 2017 boom, the entire rally from the very beginning to the very end, right up until the advent of Bitcoin futures on the CME (I know a thing or two there, too). I almost saw one well-known exchange go bankrupt at the time, but my professional instincts saved me. I also lived through the 2019 boom and Covid, then the booms of 2023 and 2024. I'm very good at reading order books, because I programmed them for other traders.

This was my first acquaintance with the markets as a student. The internet was very slow, the barrier to entry was high even for retail, and, as expected, these were also my first big losses. The market sucked a lot out of me, in the end. Thank goodness for that! The market is the best teacher. It teaches better than anyone, but it charges a lot!
