Okay. Thank you to all of you.
It's way clearer for me now, I understand better

Hello there,

The Bitcoin Gold is going to be launched on the 25th of October, and everyone says that if someone has some Bitcoins on a wallet, then the same amount will be credited in Bitcoin Gold. It was also the case with the Bitcoin Cash.
However, how do we need to understand this? I mean, when they say that the same amount will be credited, does it mean that if I hold the equivalent of 1,000 dollars in Bitcoin, that I will be given and credited this same amount of money in Bitcoin Gold when it will be launched?
Thanks in advance for your feedback
