Of course it needs digital gold, we already have fast and secure digital currency - we have Visa and Mastercard, we have PayPal and Venmo. In most countries using payment cards for daily purchases is very comfortable - fees are low or even zero, confirmations are instant, buyers are protected from fraud and in many cases can get their money back. What the world didn't have before Bitcoin is a digital store of value that can't be seized by the government, can't be frozen by banks, can't be stopped by laws and regulations.
