Why bitcoin?
Because it's more currency than anything else in this world.
Money is just a bunch of virtual numbers, that have some meaning just because we agree that they have it. It is there for convenience only and depends on peoples agreement more than any other backing up. That is why money is made by everyone.
Look in your purse. What do you see? It's just colored paper and round pieces of metal. It is only your trust and belief, that turns that paper and metal into dollars or euros or whatever currency you use.
So why bitcoin?
Because every other currency is an agreement that is being imposed on you. You have to roll with it, weather you like it or not. With bitcoin it is up to you to accept or decline the agreement. It is up to you to determine the value of them, as opposed to centralized systems, where you have to go with decisions made for you.
With bitcoin you are recognized as a part of the agreement and because of that, you are treated as an equal among equals.
