You must know what bitcoin is. In 2009, 1 dollar was worth 1308 bitcoins.
So I regret not buying bitcoin in 2009 that nobody can understand. So do you know how bitcoin gained so much value? The purpose of Bitcoin was created to send money from person to person by eliminating intermediaries, namely central banks.
After the economic crisis of 2008, people started looking for decentralized payment methods and bitcoin came out.As such, bitcoin price peaked as the supply and demand amount increased when companies entered into this business.
I guess the guy who bought two pizzas for 10,000 bitcoins, who knows how much he regrets now
