This is the case of the bitcoin fork called bitcoin cash (BCH) created last August, which experienced a spectacular surge following the announcement of the abandonment of the fork SegWit2x from Bitcoin also.
The price of the BCH soared by 130% in just 2 days (with a high of 2306 dollars at the neck of the weekend), in front of the Etherum then he went down. On Tuesday, he returned to 1384 dollars at 12:00 (UTC).
