Neither of these happened and finally I bought a diversified holding of £10,000 in 2019 to hedge against future pain. I still have this holding untouched including 1 btc and have no plans to sell it until I am sure it has hit full critical mass or goes to zero.
My question: Should I just forget about bitcoin now and go back to my business?
You have your point we don't really know what would happen in the future just like what you said bitcoin could get regulated or shut down at some point, at some point if it gets out of control.
That would only happen if things happened but if bitcoin just continues to adapt as it is today surely in the future it will be a lot more value and could even reach up to a 1million dollars of value.
Still, the potential is already in there and it's hard to take profit if you're not holding for the long term, it's better to just forget about your investment and then just come back if its bullish.
