Elon Musk is one of the richest people in the world.
There is a rumor that Elon Musk's father owns an emerald mine in South Africa.
Elon Musk's father, Errol, said in an interview that he used emeralds from an "under the table" mine in Zambia to finance his son's escape to America.
The rumor has annoyed the CEO of Twitter.
Elon Musk has decided to offer a million Dogecoins to anyone who can prove the existence of the mine.
The Twitter account DogeDesigner denies the existence of the mine and offers Dogecoins to media outlets that publish false information.
Elon Musk's offer of a million Dogecoins is equivalent to about $84,000.
The rumor suggests Elon Musk's net worth could be boosted if the mine exists.
Elon Musk has made the offer on his Twitter account.
The offer is open to anyone who can prove the existence of the mine.
Now the rumor has been gaining more momentum.
