I am kinda confused with these forks but this time I want to take advantage of it.  

I have a few questions regarding the coming fork on October 25, 2017:

• Where do I need to keep my Bitcoins to get the free Bitcoin Gold? Are there any condition to where we store it such as which exchanges or wallets supports it ?
  
• Whats the last deadline to have Bitcoins in the wallet to get free Bitcoin Gold.
  
• For example: Is it possible to have bitcoins in my wallet on 24th October and take advantage of free Bitcoin Gold on 25th October? or must I keep it there earlier for some time?
  

P.S. Sorry for my bad English.

P.P.S. Sorry if this is a wrong section to ask for such topics/discussion.
