Where do you have your Bitcoin?
I have my little bitty Bitcoin in Blockchain.info. My BitcoinCash suddenly popped up there a few weeks ago without me having to do anything.
It was accompanied by a message asking me if I wanted to convert it to Bitcoin.
Luckily, after today's big changes, I never got round to do anything with it so it is still sitting there now worth a good bit more than it was before.
