A Bitcoin ATM (i.e. "BTM") is similar to any other Bank ATM, but is used to buy or sell Bitcoins with cash, easily and conveniently.

Users can convert regular currency into BTC (Bitcoin) in real time onto their mobile device or paper wallet.

A one-way machine allows a user to buy Bitcoins with cash only, and a two-way machine allows a user to extract cash in exchange for Bitcoins they own.
