At the moment the price of a bitcoin on the Coinbase dashboard is $8247 EUR, however in the buy section it's $8840 EUR. I know they have some commissions and spreads, but that's 7%... Is this a bug or a feature?
Moreover, the sell price is $8755 EUR! Much higher than the market price! I even bought some for 10 dollars to make sure. In GDAX, which is Coinbase's exchange the price is $8244. Why does Coinbase sell/buy for so high?
