Back in 2013, my friend Lisa, who was always ahead of the curve, convinced me to buy some Bitcoin. At the time, I thought she was nuts. Spend real money on internet coins? But Lisa was persistent, so I bought a couple of Bitcoin for $100 each, primarily to get her off my back. Fast forward to 2017, the value of Bitcoin skyrocketed to nearly $20,000. I couldn't believe my luck! I sold one of my Bitcoins and treated myself to a trip to Japan, a place I'd always wanted to visit. The other Bitcoin? I kept it, just to see what would happen. Now, every time I hear about the latest cryptocurrency craze, I smile, remembering Lisa's wild idea that turned into one of the best investments I ever made.
