IF the whole world ban BTC at first BTC will Crash very hard but only for a few month, Demand will be increased while there will be no Legal Seller, All trade will go to undergrand and Black market and illegal traffic, sellers will start to selling BTC 50 X more than current price. BTC will be more expensive, As simple as that,
That was an answer for these who said BTC will die if whole world Ban it, So no BTC never Die.
if bitcoin were banned everywhere, why would demand increase? demand from who?
i mean sure, black markets could still exist, but prohibition greatly cuts markets down in size. all institutional investment would cease, mainstream retail investors would jump ship. its utility would be greatly reduced because cheap, legal fiat gateways would be gone and only expensive, black market exchangers would exist. miners couldn't operate in the open, reducing the value of the network's security as hash rate drops.
i don't think bitcoin would
die but a million bucks? sounds like crazy talk to me.

definitely, the main thing that would happen is that, if demand would not rather increase, investors and current bitcoin hodlers will not afford to sell their coins on a very low price. Even if they Ban BTC, it will still have a huge market value, so people will still going to find ways on how they can accumulate and utilize bitcoin as their currency. Eventually, the effectiveness for government to ban bitcoin isn't really contributed, meaning to say that the'res a huge reason that it will stay not prohibited as government will just waste their time and money monitoring such increase and fundamental market analysis.
