What do you think Bitcoins biggest vulnerability is?
Government would be bitcoins biggest enemy. Regulation prevents people from getting involved in crypto, thus preventing cryptocurrency's growth and adoptation. Some countries are skeptical and strict when it comes to their people getting involved to it due to scam and issue that crypto is used in illegal activities.
Government and regulators will always remain as enemies to bitcoin or any other crypto currency due to the fact that they cannot control it and it's decentralized but off-late we have come across situations like kidnappers, hackers demanding payment through bitcoins and claims that bitcoin is used as funding for terror activities and security services cannot track their activities is turning out to be a worst nightmare. But there are crypto friendly countries like Malta, Estonia as well who have seen the bright side of crypto world.
