It's kind of funny you ask this, because I've spent so much time working on getting to a place where I'm at peace with my past and don't really waste a lot of times on the "what if's," but that being said, one thing the person that I am not in this moment would do differently given the opportunity again that I had back then is that I would have saved my BTC instead of gambling it all away. That being said, it is what it is and there's no point worry about things that we cannot change. Just learn and move on.
