What is/are the fastest way except ATMs to transfer USD to BTC or ETH or LTC?
Preferably instantly, i tried coinbase, but their instantly requires to many verifications steps that takes a few days to complete... Any suggestions?
Use shapeshift.io . No account required. You can exchange immediately tho the fee may be higher than your average exchange. It's instant btw. You send the money you want to exchange then input where to get the coin you want in return.
