Long term investments are subject to market risk and capitalisation. They are not true always and can turn profitable or unprofitable at any time. In case of bitcoin which is being crypto a virtual form of digital currency is a coin which is standing on its edge. It can literally fall with blowing air in a blink of an eye. The blowing air could be strict rules and regulation implemented by government or any union of multiple countries. Have you ever thought of this topic in this angle?
Its not just investment, it is study of whole thing from politics, nation people, the legislature and amendments which can change at any time point during the present or future timeline. You must keep it in a such way that you can hold or let it go at good and bad times.
Do you think that the politics in real life really affect bitcoin? People don't care about us. The government don't consider us a problem. There's terrorism, cancer, and all the other dramas you can think of. The government and politicians don't have the time to make a move against us. Plus, they don't really have that much power here.
Remember PBoC? Literally everyone back then thought that China has the power. We thought that once PBoC made a move, we're all done here. But you see, the PBoC has already made their move and it might made some effect at their first try, but at their second try, there's nothing at all. That's when we realized that even the government of the country that was believed to be the most powerful in bitcoin world don't have any power at all.
