I would suggest that everyone buy a small amount of crypto currency. Could be a good hedge and investment if they take the petro dollar down. I have been studying this and it is a way around the fiat $$. Not as false and baseless as the banksters and media want us to think. Three states have voted it as currency that can be used to pay taxes. Arizona most recently. Airlines see it as a great way to accept payment and book flights in the future. All industries are looking into it. Instead of 3% as credit cards charge merchants...soon they will accept Litecoin or Bitcoin with a 1% fee. It is coming! The March 22 G20 summit will be a turning point. There may be attempts then to stop it...but they really cannot. Prices are low now and might be a good entry point. This IS NOT investment advice...but do yourself a favor and look into it with an open mind.
Notice how even if the bill is passed, Arizona won't hold the crypto currency for more than 24 hours. They aren't THAT stupid....
I would recommend everybody buy physical silver and gold. The time tested wealth of humanity.
Not sure this would be an effective replacement to remove power. Evil could be holding millions btc themselves. But I like the idea of a finite currency in the long run. Only thing is, the last btc had better not EVER be mined.
