Back in the day, before #Bitcoin or the #USDollar, people used a system kinda like an IOU among family and friends. Think of it as a mental note, "I owe you one." This was super handy in small circles but just couldn't keep up when more folks got involved. It's like trying to remember everyone's coffee order without writing it down - bound to mess up!
