This question already has an answer here:
I am new to Bitcoin and would like to know how to calculate the amount of profit made when Bitcoin rises. With stocks a point is equal to $1 and I am required to pay the full value of the stock so calculating profit when the stock rises is very easy. Right now, 1 Bitcoin is worth $11059.51 however I am allowed to invest less money for a small piece of it. I can invest $100, $500, or any amount less than what Bitcoin is worth. I am confused on how to calculate profit. If Bitcoin rises and to $20000.00, and I have only invested $100, how much profit will I make? Is there any easy way to calculate the actual profit of Bitcoin rising when someone invests in a small piece of it rather than buying 1 Bitcoin? Thanks for your help.
