I wonder what is the main reason why did the ethereum is on bull run? Is it because of the Constantinople upgrade?
I think the main reason for the bull run of ETH is the high demand of this crypto at the end of this year when X'mas are coming, and a lot of people want to buy ETH to hold in the next year 2019. The hard fork of Ethereum will occur in January 2019, and I think the price of ETH will rise after it happened.
