It is essentially the same but this time the risks are far greater.
Last time Bitcoin Cash only had a slim chance of toppling Bitcoin, this time Bitcoin 2X is the challenger and it has a reasonable chance. If it fails but still manages to weaken Bitcoins dominance then Bitcoin Cash and its heavyweight supporters will have another go at toppling Bitcoin. So this time Bitcoin will be attacked from two opponents both determined to topple bitcoin and take its place. If Bitcoin can survive this, it can survive anything.
