BCH and BTC are strongly correlated and I would be long on both.
My first decision is made on the real Bitcoin - BTC - because Bitcoin is the original one on which other cryptocurrencies are correlated and we see buy signals when using Ichimoku. The price is above the cloud and Tenkan Sen - the thin blue line - is above kijun, thin red one.
The BCH chart leads to the same decision
This time I prefer BCH because Ichimoku reveals a better opportunity on Bitcoin Cash via the BCHBTC chart that shows buy signals.
