Perhaps no one will argue with the fact that Bitcoin is just a digital currency.  Initially, this coin was created for payments and a limited range of tasks.  Proceeding from this, the scope of using crypto currency is limited.  Nevertheless, the prospects of development as a currency, a means of payment from this less did not.  A highly specialized asset will cope with the original purpose more effectively than a universal tool.  Judge for yourself, a professional camera will always make better pictures in comparison with a smartphone.  However, this analogy can also be used in the opposite direction, for example, you can not call from the camera, respectively, and Bitcoin is deprived of additional functions.
 The Ethereum system is a platform that is based on Block Chain technology, in other words it is not a digital currency in the traditional sense.  For example, using this system you can work with Smart contracts, and this platform can be used to further implement certain projects in a decentralized environment.  As a result, the Efirium is not interested in simply because it is a reliable means of payment.  Of course, this has a positive effect on the investment attractiveness of the asset.  However, the principle of "bearish service" can always work.  Therefore, no one can answer with a maximum accuracy to the question that Betcoin or Etherium is more profitable.  In fact, each of these systems has certain strengths and weaknesses, so there is no unambiguous inference and can not be.
