I bought $30.00 of Bitcoin. The price at that time was $6,896.00. The price now is $8,074.00. How much did I make? And how do I do the math?

  • Crazy how you make a comment like that, as if that is supposed to mean something. This is a new market, something like when Wall Street started. By no means should you judge or underestimate anyone. This is not the platform for that. So with that being said. How about teaching someone something.

  • @Badrobot, you clearly posted this naive question in hopes that it would get attention, and you could spam the comments with cloud mining links. You have been reported.

    I'm voting to close this question as off-topic because it is more of a maths or investment question than a cryptocurrency one. Nov 22, 2017 at 2:30

You have not made any money until you have sold your bitcoin. The numbers in the previous answer refer to your unrealised capital gains. Remember that you may have to pay tax on your gains if you do decide to sell and adjust your winnings accordingly.


30 / 6896 * 8074 = 35.1247099767981

So, you've made a net profit of $5.12., which is (5.12 / 30) a profit margin of 17.06 percent.

For a more indepth answers about realized and unrealized profit/loss for investments, and specifically Bitcoin, check What happens if I buy Bitcoins and the price goes down?

  • @Badrobot remember to accept this answer if it satisfies your question, don't leave it "unanswered" :) Nov 21, 2017 at 20:25
