Bitcoin Cash gained around 29 percent in a single trading day on September 22, 2026, closing at 301.19 euros against 232.97 the day before on Kraken. The question everyone then asks is: buy in or wait? We did not guess at it, we recalculated it. Over the past two years there were 49 such jump days among the largest coins. Thirty days later the median case stood at minus 6.7 percent, and only 19 of 45 assessable cases were up at all. The average of plus 23.7 percent looks friendlier, but comes almost entirely from a single coin.
