I don't recall exactly. I owned bitcoin at that time but I was merging my business with another company and I was busy as all hell. Besides, owning it doesn't mean I understood anything. Haha.
I know Brian was supporting the big blockers and when the fork occurred you got the equivalent amount of BCash, which was actually great because I just sold it for Bitcoin. But I don't think they switched to Bitcoin Cash, maybe they promoted it as "bitcoin" or something but you shouldn't have lost you BTC stack. You should have had both.
