Re: Warnings from History: Wikileaks... Cyprus....
Wikileaks funding was blocked as the payment gateways of Visa, Mastercard, and Paypal are all US based and controlled. That is an entirely different proposition to blocking financial transactions in all currencies, or at least in all stable ones that would be reasonable to use.
You are worried about laws being passed to block cashing out of bitcoins just like Cyprus?
1. The Cyprus cashing out blockade wasn't that effective as the wealthy could just withdraw their money from the UK branch of Cyprus Bank. Plenty of money rolled out but that method or others.
2. Again, to prevent cashing out you would need to block it happening in all reasonably currencies on the planet simultaneously.
3. There would undoubtedly be a drop in value but, given you cannot take my bitcoins from me like you can my savings I am still free to trade them for goods and services which, after all, is the point of money.
Unless you can block all the exits and prevent acceptance for goods and services you fail. I may not be able to swap them for dollars but as long as I can swap them for things I want I can accept them myself. I don't have to take all payment in them.
This inability to control and take what is not theirs is what frightens Governments, especially as they are all increasingly bankrupt, both morally and financially.
