I think the bitcoin won't lose or kick the bucket due to the worldwide direction. indeed the bitcoin required the worldwide direction on what I read .So it will not die because of regulation.
If t would be regulated then the opposite may happen. More people would adopt it because they know that there is already someone accountable for it since the government has already regulation applicable to it. More businesses would adopt it because the price may reach its stability if mass adoption would happen. When that time comes, we are lucky because we are still considered as early adopters of it. Along with other cryptocurrencies, people would use it for their actual use case as a currency and not just an asset for investment.
