One of my biggest regrets in life is that I bought too little Bitcoin when it was $300. I chose gold instead. Back then, ten years ago, when I was still a college student working part-time with little money to invest, I could buy about 2 Bitcoins with a month's salary of $300. However, I felt it wasn't reliable and hesitated, ultimately choosing to buy gold instead, which was $1300 at the time. By 2017, when Bitcoin had risen to $3000, I still planned to use most of the little money I earned from my part-time job to buy gold and a small amount of Bitcoin. Now looking back, the gold has only tripled in value, while Bitcoin has increased by 100 times.
