1. not stable value
2. deflationnist money.
But I think in the Future, people will think Bitcoin (2010 decade) was an important money historic breaking point.
"deflationnist money." really? Many fiat currencies only go down in value since they were invented. Go do your homework.
You right. Some fiat currencies have only performed badly but people seem to think that the might USA and pound are the only currencies in existence. Many countries from third worlds have fiat which is worthless and becomes more so every day. Bitcoin is more stable then these fiat currencies if you compare them. I would rather have something that goes up and down then something that generally just goes down. and rarely goes up.
