Was just pointing out it's easy for people to copy to digital currency and just keep making different versions of it since it's not physical. There's only 1 gold that exists and can't be copied
There's also more than one metal out there. For whatever reason, you are looking at other cryptocurrencies as if they are other bitcoins. There's gold, silver, platinum, aluminum, etc just as there is bitcoin, litecoin, bitcoin cash, etc.
Just like gold, you can't create more bitcoin. Making a new cryptocurrency based off of bitcoin code is not creating more bitcoin. You can't create more bitcoin.
People in a lab can probably create some new metal variation, but that doesn't mean anything with regards to gold. Similarly, developers can code all they want, but that doesn't affect bitcoin.
