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.
I will not try to argue with your post but it looks like totally wrong and why? did you see that? The market has plunged again and it could be another horrible thing to create panic sell. But ETH still remain strong consider it has gained the major support again.
