Back in 2017, my friend Lisa was the epitome of skepticism when it came to cryptocurrencies. She called Bitcoin "funny money" and dismissed Ethereum as "tech nonsense." One day, after relentless persuasion from her tech-savvy brother, she reluctantly invested $100 in Bitcoin, just to prove him wrong. Fast forward to late 2020, Lisa's skepticism turned into sheer astonishment. Her small investment had ballooned to over $5,000. That holiday season, she gifted her brother a brand-new gaming PC as a thank you. Now, Lisa has a diversified crypto portfolio and spends her weekends researching blockchain technology. She often jokes, "Funny how funny money isn't so funny anymore!"
