Looking at it from a background of selling products to people on huge platforms for the past 5+ years i'd say, let's look at it from a social pov.
Whats a social POV? It is what most people think of an idea, not just experts but most people.
Most people don't know anything about Altcoins, but they do know about Bitcoin.
Bitcoin to them is The OG.
If we try explaining BCH to someone new who has heard of BTC but is skeptical, they're gonna skippy skippy skeptically skip all the way out the door, Bitcoin on the other hand is a known quantity.
I recently had the misfortune to sit in a starbucks next to a Multi Level Marking schmuck trying to sell $20,000 worth of BTC to an investor who was in real estate. Apart from the cringe worthy gold chain and greasy hair, his pitch was terrible, but he still managed to make the real estate guy stick around for 2 hours, before he left promising the MLM guy that he would call.
He started skeptical, ended less skeptical but still wouldn't invest.
I can only imagine that greasy schlomo trying to convince that guy of BCH, the investor would've bolted in 5 mins.
Not taking anything from BCh, but it's just the way the world works.
E.g. the US Dollar is world famous, try convincing people that Chinese Yuan will be next world reserve currency and see the looks of "wtf is this guy talking, da fuk is china yuan"
Same concept. Just my 0.002 Bits
