When Dogecoin was launched in December 2013, its initial price was approximately US$0.00026. With an investment of R$100.00 at the time (considering the average exchange rate of 2013, approximately R$2.30 per dollar), you would have acquired approximately 166,666 DOGE.
Today, with Dogecoin worth approximately US$0.464 (equivalent to R$2.30 with the current dollar), this amount would be worth:
166,666 DOGE x R$2.30 ≈ R$383,332.00.
This is the gross value of the initial investment of R$100, without considering possible conversion, trading or withdrawal fees during this period.
