First ever bitcoin transaction was when bitcoin was used to buy 2 pizzas using 10,000 bitcoin!
10,000 bitcoin yes - if you compare the price of a pizza during that time and today - it is waaaaay to different (1 bitcoin is around $39k as of writing). I could buy myself a house and lot with that much here in my country.
and this made May 22 is known as Bitcoin Pizza Day - this marks the date where in 2010 a Florida man Laszlo Hanyecz paid for two pizzas with the cryptocurrency. Hanyecz is also the first person to use bitcoin in a commercial transaction.
