This is a remarkable and historical event for this great cryptocurrency - Bitcoin. Currently, in my area, no restaurants accept Bitcoin for payment for Pizza. However, this celebration is an opportunity to recall some other memorable events about Bitcoin, the cryptocurrency that have made a landmark in the financial system of the world.
On January 2009: Nakamoto creates 50 BTC and transfers 10 to Hal Finney, an early Bitcoin adopter.
On May 2010: Laszlo Hanyecz makes the first real world Bitcoin transaction. The crypto enthusiast paid 10,000 BTC for two large pizzas in what's now regarded as the first real world Bitcoin transaction . Back then, 10,000 BTC was worth around $40. He never knew that May 22 would forever be celebrated as Bitcoin pizza day.
On July 2010: Bitcoin starts trading. By the end of the year, 1 BTC was worth around $0.80. A run down of some remarkable events can be seen here: (
