If You Bought $100 Worth of Bitcoin One Year Ago, Here’s How Much Richer You Would Be Today
Back then, the price of bitcoin was a more affordable $474 per token — less than half the price of an ounce of gold. So, had an investor in theory decided to invest about $1 at that point, their stake would be worth about $852 today.A $100 stake would have become $85,200. Meanwhile, a $1,000 stake would have turned into $852,000. A stake worth $1,200 back then would have made its owner a millionaire today.
