Bitcoin Cash is almost guaranteed to have some value, given the amount of worthless alt coins there are. It will likely reach 10% of Bitcoin's market cap with ease, becoming as ETC is to ETH.
However, that is not good enough.
That is not enough to change the world.
To have a chance of being what we wanted Bitcoin to be - a global, permissionless, payment network and the coin that payment processors adopt - we need all Bitcoin holders to be aware that Bitcoin Cash will have value, and that provided they take certain steps, they can own their share of this value.
Bitcoin hodlers must be made aware that by leaving their coins on exchanges they are potentially forfeiting a large amount of value. They must be made aware that if they still intend to leave their coins on exchanges they would be wise to contact the exchanges and apply pressure to ensure that their Bitcoin Cash is kept safe. Exchanges must understand that there will be a lot of angry customers if this is not done.
For Bitcoin Cash to succeed, it needs to piggyback off the network effect of Bitcoin. Every current Bitcoin holder must also hold Bitcoin Cash, not just a few who were fortunate enough to control their private keys on the day of the fork.
Tell every Bitcoin user you know about Bitcoin cash.
Tell them it already has significant value, trading on ViaBTC.
Tell them they need to contact any exchanges or wallet services they use so they won't lose this value.
