Bitcoin is a strange financial instrument that is both a currency and an investment. You can use bitcoins to buy and sell things online, or you can buy and hold (or hodl) bitcoins in the hopes of turning a profit. Bitcoin is like Venmo (or PayPal), but if you sent and received stocks. This makes Bitcoin a truly unique financial invention.
One possibility is that bitcoin will behave much more like a currency in the future, and much less like an investment.
