So imagine I can make a copy of all the gold in the world and then sell it. Maybe not exactly the same but 99%. Perhaps a bit lighter or a little less golden in colour.
But in reality, this copy would be as near identical that it could be used in jewelry, electronics etc. Bit it wouldn't be gold.
Lets just call it new gold. Then I gave everyone who currently possed gold the same amount of new gold.
What would happen to the value of gold?
What do you think the value of new gold would be?
are you talking about fork in coins ? i think if gold can be copied, its value will drop someday
because copy means adding more supply to that. more supply = lower price.
but in crypto, you can see bitcoin. the value has not drop when forked.
