Last summer, I found myself sitting in a quaint café in Berlin, savoring a cup of espresso while watching tourists scramble for cash. It struck me as a bit odd that in an era of innovation, many still cling to the crinkled notes in their wallets. Just a few tables away, a couple was discussing purchasing their first Bitcoin, eyes wide with excitement and anxiety. This seemingly small moment illuminated a larger trend: the hesitance and curiosity surrounding Bitcoin. How does one actually use this digital currency, which seems equally daunting and promising?
