If you brought a US dollar into the crypto world, there would be no demand for it. Not surprising since the digital asset, argues Nouriel Roubini, has yet to move into the realm of a true currency. With no political economy to overlay, bringing the dollar or dollar-denominated assets into “crypto-world” for sale means a trader in crypto-world laughing in your face. Does cryptocurrency want to enter the realm of real currency or would it prefer remain a speculative asset? And if so, how can an argument be sustained that cryptocurrency can be used to serve the under-banked or unbanked?
