I do not think this will be a big problem.
Most likely Bitcoin SegWit solution is not going to be accepted and will crash sooner or later because of blatant mismanagement and corruption.
Investing in it will hurt you if you plan to stay there long term.
You could make some profits short term by gaming the abusive system, but that just makes you as bad as the people you criticize.

The prudent course of action is to keep your Bitcoins where they are and see if there are other parties who try to regulate or destroy the remnants of the original Bitcoin. I do not see how this is possible, however. A lot of people have a vested interest in the maintenance of the original Bitcoin; plus the cat is out of the bag anyway. Noone can stop its replication, in fact, other decentralized currencies are already on their way so that new decentralized non North Korean options are available to us regardless of what happens to Bitcoin.

Obviously, I think that the original Bitcoin is going to survive this, but there are going to be some tough times ahead of us. It was obvious from the beginning though, Bitcoin was and is a game changer and with its creation the rules of the game and the status quo have changed - leading to conflict.
