1. Restrictions from the government and regulators who keep on threatening that they may ban bitcoin or crypto in general anytime, imposing an unjustly ridiculous tax on trading and withdrawal literally leaving us with loss even if we make a profitable trade. What if a situation arises wherein we cannot withdraw even if the value of bitcoin increases as it will be of no use.
This is a common problem that occurs in many countries, we don't have to be afraid of this because we are people to have anything in the world with no exception like Bitcoin. The government is very limited Bitcoin movement because they can't control it like what they did in fiat. So that case, the government is afraid if Bitcoin become a big power that will shift their hegemony to control people. Nothing to say and we can't avoid that situation than think about how to trick them also. Today many tools which can use for hide our Bitcoin transactions to avoid surveillance from the government, just use that, and you might be able to avoid surveillance.
