ALWAYS keep your currency in your control and don't be lazy and leave that currency in online wallets. You are always better off taking the currency offline and keeping it secured that way until you need to trade it or sell it off.

Also, regarding this whole Bitcoin Cash created by the fork. It would be nice if those that hold onto Bitcoin are able to get some extra money from this fork coming up August 1st. But it can also be a flop altogether so just keep that in mind as a possibility, since this is the first time we have encountered something like this with Bitcoin and it definitely won't be the last time.
