Everyone with BTC before the fork was given equal value in BCH in wallets, so now the choice is yours, use BCH to move smalls transactions fast and cheap and use BTC for storage of wealth or sell off BTC and go balls deep into BCH.
I have both but my coins are all BCH, and a nice amount of BTC was liquidated into BCH and even a few new coins, there's a short term window to make boats loads of money in alt currency, but long run IMO BTC and BCH are the only coins that will be of value 5+ years, in the meantime it's all good.
That was now nearly half a year ago. The BCH advocates telling BTC holders that they have nothing to lose if it flips are now leaving out a shit ton of people who arrived since.
