Anybody thinking about all the DAPPS (decentralized applications) that are being created and implemented? These DAPPS are being developed as we speak and pretty soon they'll be readily available software like any other softwares. ETH will be the exclusive currency of use.
Society will need time to familiarize the use, as how we did with credit cards. Remember the Diners Club card when it was first used in the 1950s? Then the credit card was normalized in the 1960s with American Express. The first five years 2017-2022 will be an evolutionary period for the financial sector.
