The average person has no need for bitcoin , nor do they care about it, nor should they be told about it. Average people ruin things. When average people joined the internet what happened? It turned into a huge cesspool. When average people obtained automobiles traffic jams occured. When average people were given the right to vote, nation's collapsed. You get the picture.
That's a rather dim view of your fellow humans. For bitcoin to have value and to work like a currency rather than a volatile commodity, it needs to have a larger user base to provide inertia.
When I can walk to my corner store and buy a pack of smokes and a can of Monster with bitcoin, I'm going to be really happy.
If you want a secret cryptocoin, use one of the other bitcoin imitators with a silly name that no average person has heard about or will ever hear about. You and your friends can trade them for Magic the Gathering cards, or whatever you're into.
