for me bitcoin and, bitcoincash I prefer investment in bitcoin, because for me the price of bitcoin is also getting better in the long run, because the growth in the price of bitcoin is also starting to increase.
I have invested in bitcoin and bitcoin cash. BCH in the market is gradually increasing its price. Its price is even higher compared to ethereum. But of course, BCH needs a lot of time to prove its worth. If I need to invest in one coin, I'd go with bitcoin. Bitcoin has proven its worth for how many years, despite of its price now, a lot of people still patronize it.
