I don't think global regulation of bitcoin will kill the bitcoin, it will rather strengthen and more reliable, global regulation of bitcoin, is what the world is waiting for, to make the bitcoin a hot currency, and universal acceptable.
I agree. Government regulations will never destroy Bitcoin but will make Bitcoin and other cryptocurrencies authentic and secure. It will give people the impression that cryptocurrency is not a fraud. I think the government also want Bitcoin to exist for a long time that is why they do not totally ban crypto market.
