Its a FUD sir, There is no way that bitcoin can be shutted down. If it is way back 2010 then its possible but with the massive adoption of blockchain technology on every sectors in our world (financial, healthcare, sports, entertainment etc..) shutting down or stopping the crypto is impossible
Everyone of us have different perspectives about how the cryptocurrency adopt in their life. And we know that all things have metit and demerit. So for me, criminals are always in the sorroundings they find a good timing to do crime or baf things. We can't shutdown the cryptocurrency radily because we know all of us was have benefit in the cryptos. So my only suggestion is always be ready for what happen and secure your coins for all people that make bad things
