in your opinion which one has the chances to go high by 2020 .........
1. ethereum
2. bitcoin
Nothing will change, the ethereum will remain the main competitor of bitcoin and will grow proportionately in price like bitcoin. More interesting is what coins will disappear by this time.
Ahh, really?
So in 2020 wenn Bitcoins supply halves again and half as many new bitcoins can be sold and same amount of ethereums, twice as many ethereum buyers pop up so nothing will change. And that will happen because you personally will take care of it, or how?
