I would suggest you direct him/her (whoever you want to know about bitcoin) to "qoinpro.com" since the site gives clear definition of bitcoin, what its purpose, why it's made, who is the man behind it, etc. Also you can make account there coz they give free coins daily and they even support bitcoin hard fork. That means you get a new coin as a result of fork. I am not promoting qoinpro by the way but I cant see another site or blog that explains bitcoins in a simple manner and can easily be understood
