Ironic question right? Well, as a crypto lover/ investor or whatever, only one thing that comes to my mind. That is, to be honest, if I get a time machine now, I would probably travel to the past and advise myself to buy BTC when it was so low.
If I had a time machine maybe I would think of using it to go back in time when Bitcoin was small and buy as much as I could. But on the other hand, I will lose many precious moments that I have lived and maybe it won't happen again. I personally won't use it and let my life be as it is now and move on with a better life, learning from the past instead of having to go back to the past. Maybe we can have a lot of Bitcoin by going back in time but who knows it might actually change something that is actually more valuable than that. So, forget about past regrets why you didn't know or buy Bitcoin from the past. It's better to focus on what we can do now and so on
