Back in 2013, my friend Alex was an early adopter of Bitcoin. He mined coins on his gaming PC, which back then was feasible without specialized hardware. At the time, a single Bitcoin was worth around $100, and he managed to mine about 50 BTC. I remember him excitedly telling me about this "digital gold," while I skeptically sipped my coffee. Fast forward to 2021, Bitcoin soared to nearly $60,000 per coin. Alex decided to cash out a portion and bought his dream house. He still holds some BTC, convinced that the best is yet to come. These days, whenever I hear someone dismiss cryptocurrencies as a fad, I think of Alex and his uncanny foresight.
