Scam or not does not matter to me. I will take the free coins from the fork and dump them for good old BTC.
Free money is free money for me. No need to worry.
I'm just going by memory here but in the last Bitcoin fork Bitcoin cash was, initially, something like 10% the value of Bitcoin, then it shot up to about 40% Bitcoin value and now is at about 5% Bitcoin price.
I, unfortunately, sold my Bitcoin Cash at the low price - was a bit hasty there - so this time I'm hoping the same will happen but I'll hold any Bitcoin Gold I get for a bit longer before I dump it.
