Tell me all about it
The best thing of bitcoin according to me is the fact that is the first realization (materialization) of the disruptive technology peer to peer which, according to me, will affect and change (or maybe even disappear) in a radical way to many other technologies which are actually in use.
What is realization?
Peer to peer must be a part of decentralization. So, a money system with out central authority must be new thing for total human race. I admire to Satoshi for this thing. It's my favorite thing.
