Yeah, people just look to the last similar situation and assume the same results with no regard for market cycles or other fundamental factors. Last time around, I don't think Bitcoin Cash had much effect on the market. The BIP91 signalling and lock-in ended market uncertainty around the potential BIP148/UASF chain split, and the market rallied accordingly. Bitcoin Cash just rode the coattails of that rally.
So in that sense, I don't think Bitcoin Cash serves as precedent at all. It could go either way. All I know is that Bitcoin Gold doesn't have nearly the support from big companies/personalities that Bitcoin Cash had (Bitmain, Bitpay, Roger Ver, John McAfee). And they also don't have a working wallet yet, nor have exchanges said a word about it. So I suspect Bitcoin Gold will be much, much smaller than BCH.
Support this. Also would like to add that I personally dont expect nothing from this and think it will be scam in the end. For BCH we had good preparation but for this I dont see anything except the word bitcoin gold. No big news just some rumor, with this i suspect that it will end up like big scam and many will lose coins if they invest in this.
Many rush to buy bitcoin cuz they expecting to see same free coins like with bitcoin cash but dont think it will happen any time soon or will happen at all.
