You are late.
Blockchain.info already fully supports Bitcoin Cash, thus, you can send, receive and exchange BCH.
You're right. I just saw it now, I thought this was another reposting of the previous news. I should have confirmed it first.

Bitcoin cash has gained so much volume and support from many traders + miners thats the reason why blockchain.info and many other wallet services have started to support them.
Any cloned coin that can gain demand and support from community can easily get support from all bitcoin related services and merchants too like this.
You forgot that BCH also have some bigshots behind its back
