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.
Yes this is the main cause that majority of people are not related with bitcoin investment. It does not means that bitcoin is not profit making but it means that anytime government can change laws and can cease the use bitcoin so if we have even more money in bitcoin it will be useless for us.
