Anybody knows any website,where are listed all or some specific cryptocoins and places, what are accepted that cryptomoney.So i think that cryptocurrenices are just waste of time.
In terms of real world use I think XRP or ripple may have some impact on how money is moved from one place to another. Seems like a good way to use to send money to others around the world.
ETH still seems to be the most interesting with the smart contract component of it.
