It is definitely a good hedge against the dollar. But one problem with that is how volitile bitcoin is. Often people want something more stable as a hedge.
Yeah that's the only thing holding it back from being a full-out hedge. But it's certainly taking away some of the attention from gold. With all this heat about a trade war, you'd think that gold would be soaring. But it's been dragging it's heels down bit by bit. Meanwhile, bitcoin is breaking out of its yearlong downtrend and starting to look like it wants to make its way back up.
I think in becoming a hedge, it's also serving to provide individuals with currency devaluation protection. Most Asian countries are devaluing their currency in response to threats of trade war, and normal people like you and I want to protect ourselves. Naturally, we use bitcoin to do so.
