Since crypto is so volatile as a whole, AND since this fork thing crept up so suddenly - and without giving most of us busy people proper time to react soundly - I think the conservative approach taken by Coinbase is ideal for me. This recent article is a good read :

Trust Us On Bitcoin Cash Say Coinbase’s Brian Armstrong

I mean, the Coinbase folks have a good enough track record of making cautious decision AND making serious efforts to protect user account privacy, and so it is more valuable to let THEM weigh the risks, take the conservative approach, and if Bitcoin Cash DOES do well it APPEARS that they are insinuating that they will pay out some/all of that which is due to BTC holders. My guess is that they will put the Bitcoin Cash in some sort of escrow type account, and then if/when they feel it is a stable/valuable currency they will release the shares to users. I could be wrong of course, but this APPEARS to be the logic behind what they are doing - that is, proceeding with caution in order to avoid exposing account holders to excessive risk. Any thoughts?
