I know ETH fork new coin and I want to know how ETH prices change. And Should i buy ETH this moment?
Constantinople was postponed due to an error, but there is a new date for 02/25/19, and the latest news says that everything is going according to plan. We wait. This will not be a new coin, a team working on improvement. When you are asked to buy you ETH or not, it's just your own business. Follow the news of the cryptocurrency market, it will be easier to make a decision.
Before tapping a new coin, the base coin is always increasing in value. On January 11 and 12 there was information about the appearance of the forhere ethereum - ETCV and ETN. They turned out to be a scam. I also met information about another ethereum fork - ETHEDV, which is supposedly scheduled for the end of February. Most likely, this offshoot will be a fraud. On February 27, five different improvements called Constantinople will be introduced into ethereum, while no new coin will be formed. Still other improvements called Serenity are planned at the end of this year, or at the beginning of the next. This should significantly increase the popularity of ethereum and, of course, its price.
