I opened my first stocktrading account in 2007. I did more out of curiosity than anything else and in the end I didn't take as much interest as I should have. It turned out to be a good thing because a few months later everything went to hell in 2008.

But a big downside to that was, that I did not get to learn much. I can only Imagine if I had learned it at that time, there would have been more chances that I would have been introduced to the crypto at a very early point of time.
