Simple definition - Bitcoin is a one of digital currency, created and held electronically. No one controls it or handles it. Bitcoins are not physically, like dollars or euros or other – they're produced by human and web economic experts.
"Bitcoin is an electronic store of value and medium for trade, that uses a combination of algorithms and other code to replace the need for a trusted central bank, and allows for quasi-anonymous direct transfers of value between peers, without middlemen."
