It doesn't matter. These people don't buy BTC to use it. But Bitcoin is there to be used as P2P cash. The people who buy Bitcoin to use it buy BCH.
You could also say to buy #Litecoin for usage. the Litecoin blockchain is quick in transaction times and its one of the longest securest blockchains in exsistance now.
because Charlie Lee left, people lost interest. believe me if we would of had massive adoption right when BTC and then LTC forked off.... BCH would not be here
This is a good conversation among "crypto enthusiasts" not the masses. we need to bring adoption by letting everyone know BCH is what should be bought not BTC
