Ok, so I use blockchain to store my wallet.
I notice that I'm able to access a hidden away part of my profile on the website to access Bitcoin gold, and I notice my balance of BTC has remained in tact..
It appears that I now own both BTC and bitcoin gold?
This makes sense, because my wallet would contain the same data on both blockchains. Therefore, I'd be able to access the wallet on both blockchains and send or receive from each while not affecting the other.
Am I missing something here? I've been reading about some people saying that blockchain.info will be converting everthing to bitcoin cash, which of course I don't.
Sorry, but it seems to me that you have misunderstood something. Or you just didn't explain it well?
How can you see Bitcoin Gold in the blockchain.info wallet when it doesn't exist yet? Maybe you mean Bitcoin Cash (BCH)?
And why would blockchain.info hide that from you?
The truth is that blockchain.info has enabled its users to withdraw or exchange the BCH that they got after the last fork. As far as Bitcoin gold is concerned, we still have to wait for it. They will probably allow us to withdraw that in a similar way.
If you are in a hurry, you can always export your private keys and import them into the Bitcoin gold wallet when it's available.
