I see that BTC is and will always be the strongest currency in digital finance technology. But at the current pace, the ETH will follow closely and have a remarkable speed of technological development. But the value of BTC is still higher than ETH in the future.
Well I always vote for bitcoin highest potential among all kind of coin in the Cryptocurrency but of course I couldn't set aside to the high potential and possibility also of ethereum to soar high in the next years or even in 2020. So I'll just wait until this time to come and watch which crypto will going to soar high either bitcoin or ethereum.
