Why we want the comparison of bitcoin or ethereum I don't think it is required. As we have seen bitcoin crossed the milestone of 14000USD where we are comparing the ethereum 450USD in what sense I will go with ethereum due to low price or any graph of potential is available its and altcoin to bitcoin so I don't want to take any risk in my investment where we have clear picture that bitcoin is doing well and it has a long run. I prefer bitcoin only.
