<p>No, it will not be easier. The "difficulty" of mining is determined by the difficulty (the value).

@Andrew, Couldn't a fork decide to change the adjustment window?

@Pacerier yes they can do that. However it seems that Segwit2x does not have any plan to do so.

@AndrewChow, Btw, since all miners have decided to support branch 2, does that mean that relatively speaking, mining going to be much much easier on branch 1?

@Pacerier No, read the answer to this question which asked exactly that. The same answer can be applied to the Bitcoin (non-segwit2x) chain as well.

<p>Is there a need for people to run full nodes that are mining on CPUs when/if the SegWit2x fork occurs?</p>

<p>Will almost all of the mining power be switched over to SegWit2x?</p>

<segwit2x>
At the moment SegWit2x forks, will mining be way easier?

Is there a need for people to run full nodes that are mining on CPUs when/if the SegWit2x fork occurs?

Will almost all of the mining power be switched over to SegWit2x?
