Its is not clear though when and how are we going to get the free bitcoin gold. Wait for exchanges to announcement if they are going to support it. Oct 25th is still far, so wait till we get closer to this so that we can have a clear view on the direction of the split.
It is the exact same scenario as the last hard fork. You will be able to move your Bitcoin into a wallet (bread) and collect free Bitcoin Gold that is equal to the number of Bitcoins that you have. So you need to make sure that you move all of your Bitcoins to a private wallet to take advantage of this. You are able to basically get free money which could significantly boost your portfolio balance.
Yes, if we are going to based on the Aug 1st split scenario, we should be moved or coins to a wallet that we have total control of the private keys to be able to claim the free money. Just be aware that there will be a lot of people taking advantage of the situation and just download a wallet that is trustable.
