This doesn't make any sense. Bitcoin has fallen but to a relatively small amount of what BCH has gained. Literally billions of dollars out of thin air overnight. The value isn't coming from anything. Yes I'm aware that's how a bubble works. But I've never seen anything like this.
Or am I missing something?
Sometimes the crypto market is irrational. Other times, it is being controlled by various interested parties. There are also temporary moments where technical factors play a role. I think the current price of BCH has a bit of all of those things influencing it right now. It doesn't seem sustainable for too long. BCH could eventually be worth something, but it currently has at least a few problems:
(1) the mining network is insufficient as presently structured to support a high volume of BCH transactions; and
(2) BCH currently has no real world use.
Until those problems are addressed, I don't see how it could maintain the current price.
