Am thinking of claiming my BCC later (not soon) is there any potential drawbacks?
My coins are in electrum and other cold storage.
I'm in no rush. I'm not doing a thing right now. When the dust settles (weeks, months), I'll split my coins and decide what to do. I want to be very careful not to get replay attacked, and also may as well wait until the Bitcoin Cash chain adjusts difficulty so we have normal block intervals again.
