Bitcoin, created in 2009. The idea of Proof-of-Work was first formulated by Adam Back in 1997 when he published a paper titled "Hashcash — a countermeasure to denial-of-service attacks." This work served as the foundation for Satoshi Nakamoto when developing the concept of Bitcoin.
August 18, 2008 — the true birthday of Bitcoin. It was on this day that the domain bitcoin.org was officially registered.
On January 3, 2009, the first block was formed, which included a headline from The Times newspaper: Chancellor on brink of second bailout for banks.
The first transaction was made on January 12, 2009. It was addressed to Hal Finney and contained 50 BTC.
According to preliminary estimates, the last Bitcoin will be created in 2140.
Various estimates suggest that about 20% of all BTC are considered permanently lost. This is due to many people who started mining or buying Bitcoin in its early days losing access to their wallets or forgetting about the existence of cryptocurrency.
On October 29, 2013, the world's first BTC ATM was installed at Waves Coffee House in downtown Vancouver. Following this event, the price of Bitcoin increased by $126. There are now over 30,000 crypto ATMs operating worldwide.
