I don't think bitcoin will die just because of those regulations instead it may become beneficial for every user because it may give more security from hackers all over the world. What's important for everyone is to feel safe storing their money in their bitcoin wallets.
Global regulation will give a higher security for bitcoin and more people will trust bitcoin because they now know that there is a regulation that they can be a basis for them to trust bitcoin since the government from different countries already made up a regulation that will add a layer of security for its users.
Regulation is needed but i think its not everything for bitcoin. We know bitcoin is decentralized system and no one control bitcoin supply. Regulation will give more confident on investor.
With regulation, investor more safe to place their fund on bitcoin because bitcoin is legal.
