Bitcoin Cash seems to be a last ditch attempt / temper tantrum. Don't see it amounting to much as it doesn't have the Bitcoin brand name (among other things). Should be interesting to see though moving forward.
I just published a book on Amazon, called "Welcome to the F*cking Show: Bitcoin and Your Future With Money". If you have any new friends in crypto tell them to check it out, it's the quickest cutting of the crypto learning curve out there (I know, I've read all the Bitcoin books out there).
