Not really sure why they decided to look at London. What the Hell's in London related to crypto? Article author assumes wherever legacy finance is, Bitcoin's bound to go? I don't mean to say London doesn't have a significant number of bitcoin users, but the last time I read a BTC-related press release out of London was, ummm..... never, and considering favorable legislation and a strong user base already exists in the stronger economy of Germany, looking at London as some kind of "capital" seems left-field.
I agree. I doubt that the "capital" of bitcoin will be where fiat based money centers are.
Personally I would predict that Vancouver BC will likely somewhat be the btc capital as it is the home of the first btc ATM.
