In May of 2010, someone on a Bitcoin forum by the name of Lazlo claimed to have bought two pizzas for 10,000 bitcoins. It was the first time anyone had purchased anything with the new digital currency, which at that time was valued at practically nothing.
Today, the cryptocurrency market is worth nearly $19 billion and those 10,000 bitcoins would be worth more than $10 million. Most of the cryptocurrency market is in Bitcoin, followed by Ether, the currency used by the smart contract platform Ethereum. Now tech giants, like Microsoft, IBM and Amazon, as well as major Wall Street banks, including JPMorgan Chase and Citigroup, are investing in blockchain technology, the underlying class of technology that started with Bitcoin. Infosys, TCS, HCL, and Accenture are working on blockchain-based products for banks as well.
