/What is Bitcoin? I see it in the news, just haven't followed it. I know it is some sort of fake currency.
Not exactly fake, merely virtual and highly encrypted, and no more artificial than most modern currencies. It is a limited currency with a fixed number of bitcoins permitted world wide. Untraceable for goods and services, so rather popular with the "less savory" aspects of online commerce, though the closure of The Silk Road has caused some problems.
