This is one of the statement that caught my attention
"A director at Germanys central bank said any attempt to regulate cryptocurrencies such as Bitcoin must be on a global scale as national or regional rules would be hard to enforce on a virtual, borderless community."
The real enemies of cryptocurrencies are the one managing the banks. They wanted to destroy the crypto world for it affects their businesses and they are losing too much investors. This statement, in my opinion, shows how desperate they are to say that it should be globally regulated. Well, good luck to them.
Of course banks may worried of losing their income and clients if cryptocurrency will becoming a currency used globally. Because banks are mostly protected with the governments for sure they will protect them, in fact government still generating income them too unlike having these cryptocurrency. But I believe it won't make crypto stop from spreading and it's is not totally a barriers, still it will make way to inform others the goodness of having this new generation of currency.
