I doubt that the United States is on the brink of another civil war. There is civil unrest because a lot of rather brainwashed college students are acting like children, but far more dangerously since they are adults now.

If anything, the opposition that started the unrest, mainly SJW who are part of BLM, AntiFa, and the leaders of BAMN are kicking and screaming like dying animals, as the Alt Right, Ethnic Kekistanis (which is a meme that the opposition takes far too seriously) , and average Americans who are getting tired of the childish games.

As for the market, no market is perfect. It's the nature of the beast that old companies will fall and new ones rise, and when it comes to investments; go with what you are willing to support and think will succeed, not leaping in after the hype trains have already left, like ZCash.
