Since I'm new to this development, I'd seen information about the new digital currency (Bitcoin) online as I tried to learn more about it. There are countless articles on blockchain technology and the idea of mining on Google. Google searches return a ton of articles discussing the blockchain system and the idea of mining. However, I've discovered that none truly respond to the query "What is Bitcoin?"
I can produce a one-pound bill for a friend to grasp and inspect if they were to ask me, "What is a pound?" When he inquires about what a bitcoin is, what can I provide for them to review? Is there a list of figures I can print out and use as my reference? Alternatively, should I point to an entry on a public ledger and say, "There! That shows my bitcoin history!"

Basically, I'm curious to know what a bitcoin or any cryptocurrency unit looks like in real life.
