Bitcoin has a larger community and still many technical innovations in the bag (segwit, lightning, tumbling etc.). If they fully exploit their potential, the market will be purged. What can BCH do better than BTC? Please do not come now with the low fees. If you look at the number of transactions on https://onchainfx.com the ratio is about 6:1 (BTC: BCH). If the same number of transactions run over the BCH blockchain, there is no longer a fee advantage!
