Bitcoin mining during this era was quite profitable, but I'm unsure if you're referring to cloud mining, as there were many scams associated with it at that time.  So, how long did you work with Bitcoin mining?  Were you able to accumulate Bitcoin during your mining activities?

I've often heard people lamenting their decision not to invest in Bitcoin during its early stages, even when it seemed almost worthless in the market.  Comparing Bitcoin's price today to that year, it has multiplied many times over, but all you can do is move forward and start reinvesting.  In ten years, you might look back and feel the same way about being overly cautious.  Your mistake was not taking the risk, and yet you still doubted Bitcoin.
