The image mentions "Satoshi's" 50th birthday because, according to data recorded on the P2P Foundation profile, Satoshi Nakamoto—the pseudonymous creator of Bitcoin—gives his birth date April 5, 1975. This implies that he would have turned 50 in 2025.

However, this date does not necessarily reflect his true birthday, as his real identity remains unknown. It is believed that he may have chosen this date symbolically, as it coincides with an important historical event: Executive Order 6102, signed on April 5, 1933, in the United States, which outlawed the private ownership of gold. This fact resonates with the principles behind Bitcoin, which seek to decentralize and protect wealth from state control.

Therefore, Satoshi's "birthday" is more of a symbolic tribute than a celebration based on verifiable facts.
