Bitcoin is the original cryptocurrency, created in January 2019 after a devastating financial collapse. Someone (or a group of people) called it Santoshi Nakamoto - and it was still a mystery to them. Bitcoin is driven by a decentralized blockchain. A blockchain is basically a block of data that cannot be changed once the database is created, adding regular information that reflects every transaction made on the bitcoin network. https://youtu.be/s4g1XFU8Gto Blockchains are stored in thousands of computers worldwide and decentralized - making them particularly resistant to failure. Bitcoin blockchain is transparent - anyone can see where coins are being sent and which wallets contain coins. What’s hard to know is which wallets make it a virtually anonymous payment system if you don’t spend a lot of time and effort following the bitcoin trail across the owner-blockchain. Any amount of bitcoin can be quickly shipped anywhere in the world for a fraction of a dollar and is separate from the world banking system - making it a powerful alternative currency. 💘💘💘💘💘💘💘💘💘💘💘💘💘
