Hi, apologies if this has already been asked .. I saw a few topics explaining a bit but I am still confused.

I have a little bit of money in bitcoin.. on Coinspot.. Is the Bitcoin Address my bitcoin key?? I assume it is.. but I am wondering why we need to put it in a wallet even tho I believe Coinspot will give out Bitcoin Gold after the fork? I do have a blockchain.info account... should I put all my bitcoin in there before the fork? Will that site automatically give Bitcoin Gold ? Clearly I'm a bit new to all this.. but any light you can shed on this would be helpful.

Thanks..

John Titor
