This is only information that the hardfork will be made later. It will not change too much, except that Ethereum price will start to grow later - after hardfork
Not all hardforks can make growth in the market. we have to wait for the response from the communication after hardfork. nothing will happen. what we hope for is good news continuously.
if you talk about hardfork then it is information that will not give a good influence on the price of coins because usually when hardfork occurs the coin price will fall again, from experience some time ago hardfork is not a determinant of cryptocurrency price increases.
