One of my biggest regrets in life is that I bought too little Bitcoin when it was $300, choosing gold instead. Back ten years ago, when I was still a college student working part-time with not much money to invest, I could have bought about 2 Bitcoins with the monthly salary of $300. However, I hesitated because I thought it wasn't reliable and ended up choosing to buy gold, which was $1300 at the time. By 2017, Bitcoin had risen to $3000, and I still planned to invest most of the little money I earned from my part-time job into gold and a small amount into Bitcoin. Looking back now, gold has only tripled, while Bitcoin has increased a hundredfold.
