There are already a lot of threads about this topic.
But to make things clear, there will be a new coin with Bitcoin's current chain that will split after 25 October.
After the 'split' happens you can claim your Bitcoin Gold with your Bitcoin wallets' private key.
The coin will have different features then the 'official' Bitcoin, and will be an altcoin.
All it is is just another fork in what will likely be many to come. Bitcoin Gold, Bitcoin Silver, Bitcoin Diamond... starting to think we are playing Pokemon all over again. lol
Although I must admit it is really cool how people who own Bitcoin automatically just get free money all of the time from these airdrops. Byteball, Bitcoin Cash and now Bitcoin Gold. Free money for clicking a few buttons. Seems legit.
I agree. And that's one of the benefits of holding bitcoin for so long.
Free money for just having
BTC in your wallet.
But there are moments that you just want to encash because of the roller-coaster ride of
BTC (i.e. when China decided to ban ICOs, etc..)
