If any crypto currency were to catch on, the dollar would lose value and the crypto currency would replace it.
Once that happens, there would only be a global cashless society.
Watch the U. N. pounce on that like a rat on cheese.
Imagine one massive conglomerate making all the decisions for one massive crypto currency.
Then imagine a government taking over, and telling you your rights to your crypto currency had just been revoked globally.
A good barameter as to whether something will enhance individual liberty and economic freedom or impede it is to see who supports the concept and who opposes. Right now crypto currency is more like kryptonite to big government world bank types. Crypto currency scares the crap out of big government. The left fears crypto currency. Wall Street repelled it until they could no longer ignore it. Every central banking authority has called it a Ponzi scheme, a scam, fraud and everything else in order to try to scare people away. It’s a major threat to their control. That should tell you something.
