This morning I just realized that today marks exactly 17 years since Hal Finney sent a tweet that has now become part of Bitcoin history. On January 11, 2009, he posted "Running bitcoin" on Twitter, and interestingly, one day later Satoshi Nakamoto sent him 10 BTC. This wasn't just an ordinary transaction, but the first Bitcoin transaction in history.

Why is this important? Because without Hal Finney's genuine belief and immediate attempt to run Bitcoin from day one, Bitcoin might have just remained a white paper that few people read. Hal Finney essentially proved that Bitcoin is not just a theory but can actually be implemented. He was a true early adopter who truly understood Satoshi's vision.

The funny coincidence: exactly 15 years later, on January 11, 2024, the SEC finally approved the first physically-backed Bitcoin ETF. So the same date as Hal Finney's historic tweet became another milestone in Bitcoin's journey—from just an experiment to a recognized investment instrument officially approved by America's largest regulator.

Thinking about it, Hal Finney is one of the most underrated figures in crypto history. He’s not the most famous, but his contributions are fundamental. From the first transaction to helping validate the network, Hal Finney is a living proof that Bitcoin is real and can be run from day one.
