At a point began to wonder what could be responsible for the upward movement of ethereum. Although, the price of bitcoin is also going uptrend, which could have also had some positive impact on the growth of ethereum. Nonetheless, i discovered that the fast and significant growth of ethereum is due to the rumour of the hardfork, although the exact date is not yet announced.
Yes, I am very sure the price of Ethereum will rise again before Hardfork happens later, and now signs of an increase have occurred. And for Hardfork there are still 2 weeks left, so take advantage of this moment.
