On this day in 2017, 58 companies representing over 83% of Bitcoin's hash power signed the 'New York Agreement' — a closed-door deal to activate SegWit and simultaneously double the block size to 2MB (known as SegWit2x).

On this day in 2010, Laszlo Hanyecz paid 10,000 BTC for two pizzas, marking the first ever real-world commercial transaction using Bitcoin. Happy Bitcoin Pizza Day!
On this day in 2021, Bitcoin crashed nearly 30% in a single day — falling from $43,000 to below $30,000 — as China announced fresh crackdowns on Bitcoin mining and trading. Over $8 billion in leveraged positions were liquidated.
