The biggest reason I like bitcoin right now as an individual, is actually as a store of value (wealth management).
As a merchant, btc is obviously superior (credit card merchant fees are a killer)... And I think this will drive adoption.
Doesn't seem to be storing its wealth very well at the moment. Whilst the benefits are there to merchants who use payment processors, there's not much safety for the consumers, especially when it loses value before you get the chance to spend it.
It's storing the value. Volatility is expected at this stage. Fiat is guaranteed to inflate, but there will be only 21000000 bitcoins ever mined.
