There seems to be a fundamental misunderstanding in the crypto space about BCH.
It has as many units as BTC has. That's around ~16.4 Million at the time of this post.
Very few have made it on to exchanges. Many people were not able to use their wallets to deposit to exchanges, and the very few exchanges that are operating have very limited support, if at all.
Once this bottleneck is out of the way, you have 16 million reasons why BCH could be sold into, heavily.
I'd factor that into your trading plan.
Sell Bitcoin Cash at the risk of losing out big.
