i think you should not sell your Bitcoingolds because even the passing of bitcoin in its name is enough to gain value these days
I do not think that it is so simple. I understand your point, what
happened with BCH is not cause of same name, some people made
huge effort do push price so high.
But who knows who is behind that bitcoin gold, we will see couple
more forks, and couple more coins, some of them will gain value with
time, and it is good to hold any coins you have.
I see myself as a holder, and I have some gold tokens from that fork
but just a little, I will hold them, but I do not plan to buy more of it. My
goal are some other alt-coins.
