Bitcoin is invented by Satoshi Nakamoto but it is common knowledge that his identity is not known.If there arise any dispute related to bitcoin or its ownership,how would it be settled by court of law or in other words who is the legal owner of bitcoin?
Legally, bitcoin does not belong to anyone. He is a folk art, because no one has received a patent for his invention.
If a dispute arises in the courts or anywhere else, the one who legally had bitcoins in his wallet will be considered the owner of bitcoin. That is what will need to prove, and not the history of his invention.
