While it is true that the ethereum and Ripple platforms have seemed to offer more advantages than bitcoin for certain practical uses, that does not necessarily make them better options in terms of their viability as currency. In any case, it could be said that these three cryptos still belong to a first generation of cryptocurrencies that could be displaced by the newer advanced generations that are to come, although I have no doubt that these three will continue to play an important role during the next ten years.
