Digital currencies are problematic monetary advancement that can possibly upset the current monetary structure and change how banks and money related foundation work. Prior all the money related exchanges were empowered through national banks (straightforwardly or in a roundabout way).Now, with the evolution of Bitcoins, the scenario has changed. Bitcoin and Ether and all these cryptocurrencies are representing a different type of asset class; a different type of trade-able commodity. Similarly, many banks now trust bitcoin enough to use it for payments.
