As of now, we still cannot tell whether it is Ethereum or Bitcoin that would prove to be profitable in the end. There is still a good deal of time left before the curtain of 2018 finally falls. If we consider what happened last year, the surging of the prices happened in the later part of the year. We still have to wait a little for that. We are almost at the end of September. These are times full of suspense and excitement. As for me, in terms of percentage growth, that would be Ethereum. Primarily because Ethereum is still way cheaper than Bitcoin.
