I couldn't disagree more strongly re: "BitCoin on the other hand is neither a necessity or something people need". It is a superior option to central bank fiat dollars as it cannot have its value diluted by money printing. How dare the public want a currency that is private and cannot be taxed by inflation!
As for your panic about Bitcoin being for criminals... There are far more crimes paid for in USD than in cryptocurrencies. Not to mention that if crypto currencies weren't available, criminals would simply find another way to do business.
I suppose in your world the 99% of people using Bitcoin for good reasons should be shutdown due to some lame effort to obviate the black market?
Bitcoin is a blessing for the freedom lover and curse for the tyrant. No points for guessing which you might be...
Thanks for the BIG comment! :)
