A common area of confusion when talking about Bitcoin is the use of the uppercase “B” versus the lowercase “b.” What is the difference, and when do you use each one? In this post, we take a few minutes to explain what each of them represent, and how to use them.
Bitcoin with a capital “B” is typically associated with Bitcoin the protocol and payment network. The uppercase form, “Bitcoin,” is also often used to refer to as the ecosystem as a whole. Using Bitcoin with a capital “B” is the common way of referencing Bitcoin when writing about it in general terms.
An example would be, “I just learned about Bitcoin, and it’s a fast and cheap way for merchants to accept payments.”
Bitcoin with a lowercase “b” written as “bitcoin” is usually associated specifically with bitcoin as the currency. When you intend to reference how much of the currency was transacted, or you’re focusing solely on the currency and not the broader payment network or protocol as a whole, you can use the lowercase form, “bitcoin.”
An example would be, “I just sent two bitcoins from my Blockchain Wallet to the merchant.”
These are not hard and fast rules, but they can helpful when trying to avoid confusion. Whichever way you decide to write Bitcoin, making sure you provide adequate context is usually all you need to ensure you’re explaining yourself clearly. It becomes particularly significant to draw the distinction when writing about the technical aspects of Bitcoin, and when explaining the differences between the protocol and the currency like we did here.
