I can't even understand how can people use cryptocurrencies without mixing. Don't unmixed crypto let veryone know precisely what, where and when do you buy? Imagine Visa/MasterCard would openly post a realtime-updated, anonymously-accessible list of every transaction made with any card, showing the card number, place, time and the bill value. Wouldn't this cause a global outrage?
