I mean let's face it, it's easier to handle money electronically than with papers in the hand. And if we compare fiat on the bank account and the blockchain money guesses who have the advantage...well not quite yet, but the potential for the blockchain is huge.
The advantage of electronic money is the major reason that bitcoin and digital currency have not been dismissed or jettison. The usage of electronic money helps in the understanding, usage and near adoption of cryptocurrency. It would have been a total failure if there was nothing like electronic money in the first place. This is why we still hear of bitcoin and altcoins, otherwise, it would have been long forgotten to the anals of history.
