One law passed against Bitcoin will stop everything?
The bare minimum that can be done is to regulate bitcoin or for a nation to proclaim it an illegal form of payment (which some countries have already done). In the future, I don't see bitcoin being outlawed completely.
Bitcoin has died too many times already, I can't wait to see that happening over and over.
What do you mean by bitcoin dying? is it in price or what? in terms of price? The reason for Bitcoin's price decline is its volatility, however, this does not make it a death asset. It continually changes in price but bounces back at least.
