Where is cryptocurrency used?

Cryptocurrency can be used in many ways.  Common uses today are:

• Used to purchase products from participating sellers. (such as www.overstock.com)
• As an inexpensive way to transfer funds to friends, family, and strangers.
• As a store of wealth (like gold)
• To invest in innovative early-stage startup companies (Can be like getting stock in a new business)
• Pay salaries
• Pay taxes (in some US states)
• Donate money (to some charities)

In each of these cases, the destination must be a person, organization or business that is willing and able to receive these funds.

But it is important to also know that cryptocurrency is not universally accepted by everyone.
