$BTC

Bitcoin is a currency native to the Internet. Unlike government-issued currencies such as the dollar or euro, Bitcoin allows online transfers without a middleman such as a bank or payment processor. The removal of those gatekeepers creates a whole range of new possibilities, including the potential for money to move around the global internet more quickly and cheaply, and allowing individuals to have maximum control over their own assets.

Bitcoin is legal to use, hold, and trade, and can be spent on everything from travel to charitable donations. It’s accepted as payment by businesses including Microsoft and Expedia.
