If you don't believe me, find the smartest people you know who are professional crypto investors, they will say they secretly hold bitcoin cash but never speak out because they will immediately be labeled as "scam investor", and nowadays character assassination is really scary on Twitter so most people who actually know stuff stay quiet.
The whole Bitcoin thing is meant to be forked, and that's the whole point--that's why Bitcoin as a whole is anti-fragile. If something doesn't work out with one approach, there will be another fork of Bitcoin that may succeed with a different approach, but the original Bitcoin holders--unless they're stupid enough to sell everything just because they want "the real bitcoin"--will keep holding the same amount of fork coins, so everybody wins.
As for the details on Bitcoin vs Bitcoin Cash, they just have different philosophies. Bitcoin wants to focus on stability whereas Bitcoin cash wants to focus on usability. None of them are "scams" and there's nothing wrong with each party. Some people have strong opinions towards either of the forks, but most old Bitcoin investors stay quiet and are just waiting out to see how it all ends, because they have nothing to lose. If Bitcoin wins, then good. If Bitcoin cash wins, that's also good because they have the same amount of coins.
Think about this for a moment. What would happen if Bitcoin Cash dies because "it's a scam", and the original Bitcoin is the only option left? And what if that approach doesn't work out? Then we are left with nothing. I think it's great that these two forks co-exist for now and have chance to prove themselves.
