1) she talks of economics but seems to not understand the basics
2) there is not a grand total of $12-$13billion invested.. there is a grand total of a few million that has pushed the price of a few thousand coins on an exchange. which then has made a vapour VALUATION cap of $12-$13billion.. but that does not mean every coin in existence was paid for at that calculation.
3) currency is anything. money is a subset of currency that is more of a recognised and utilised medium of exchange. so she would have been better off saying how bitcoin is not as common as money. rather than saying bitcoin is not currency
4) there is not $12-$13billion 'making a bet' either.
5) paypal is not a currency.. its a service.. should we start calling bitstamp a currency, using her logic.. um no
Just like that, someone is lacking basic knowledge and trying to explain anything? omg.
