I am seeing an enormous amount of ignorance on this thread.

First most, if not all of those posting here, do not understand that China has a censorship/firewall system that can block anything and everything related to BTC if they so choose.  How can people put their money in something if they have zero ability to access exchanges let alone have the ability to see the current price?  China already does this to a large % of websites and search engines.  Most businesses and government entities like the US military have had these censorship systems for years.  It's just a matter of how far of a web that they want to throw down on their people.

If there is a financial crisis in China, and it's in the cards, there will likely be capital controls.  The first target will likely be cryptocurrencies to stop outflows.  The USA is already doing everything they can to enforce capital controls without actually calling them as such.  How long will it take or what event must occur before covert controls do not turn overt?  I read things about the US Constitution.  Since when has it been followed?  Most laws on the books now, especially financial, are unconstitutional.  The problem is that politics prevents these "laws" from ever making it to the Supreme Court to be overturned.

Cryptos can be shut down by most governments and at any time they choose, regardless of their laws.  Martial law can change everything regardless of what is on the books in a democratic system or a republic where the individual is sovereign.

No matter how much people are insisting it, they understand neither due process or history.  They don't understand that governments, even in "free" countries can seize or censor whatever they want whenever they want to do so.  In some ways, the internet makes censorship even easier than ever before.  This is the true risk of BTC...and probably one that most do not want to think about let alone admit.
