Nevertheless, I have a couple of thoughts. For one, at the end of the quiz, it says 'well done sir', presupposing that the quiz was done by a man, whereas it's not always true, so makes it kind of offensive. Another thing is that I did not get why the highest price on the Coindesk index was $1165... Coindesk is still working, so it shows the current price of Bitcoin which is clearly more than that. I was looking for a $20k answer or something. Could you or anyone explain this one?
