On the other hand, Bitcoin can be divided 100,000,000 times over. This means that you could spend as little as ₿0.00000001. You will note the ""₿"" symbol, which is the Bitcoin equivalent of ""$"". Sometimes you will also see the use of BTC, instead of ₿. By way of contrast, Bitcoin can handle very small payments — even those less than one US penny! \================================================================= ## QUIZ **Question:** What is the smallest amount of Bitcoin one can own, or use? **Answer:** 0.00000001 BTC **Feedback:** Yes.
