The sleek, new BUTLER card gives you a real-time visual display of your cryptocurrency values against major real-world currencies. No bigger than an ID card and just as slim, the BUTLER card’s two embedded, super sharp, easy-to-read screens are linked to the BUTLER app, which constantly updates and averages cryptocurrency relative values. One BUTLER screen shows your holdings, the other displays their value against the USD, Euro or major currencies you choose, even gold.
