Bitcoin started around nine years ago and only in recent years, has kicked off.

CEO and founder of Auckland Block Chain Studios Centrality, Aaron McDonald, joins Vaughn Davis talking Bitcoin.

Mr. McDonald explains Block Chain is much like a public ledger, wherein anyone can add Bitcoin transactions to that network (as long as they follow the rules).

Currently there are about one million untouched Bitcoins sitting in the account which are now worth billions. It is only through mining and minting that these Bitcoins will come into being.
