Yes, indirectly the presence of BCH, is indeed the main cause of the breakup of the bitcoin community,
I hope they soon realize and return to using bitcoin, before truly regretting later
What breakup? I see people defending many altcoins especially ETH and XRP but there's really not many BCH supporters out there and it's reflected in its price. BCH is gaining value only when Bitcoin does and when Bitcoin loses value BCH loses much more at the same time. In time more people notice that it's not worth it to buy BCH because it depends on Bitcoin. You can buy Bitcoin instead and be much safer.
ETH and XRP have their uses but what is the use of BCH?
