As said one million times. BTC act much more like a commodity.
I believe something else will compliment BTC in the future. BTC being the gold to save, something else being the cash to spend.
But why would anyone abandon the existing Gold/Silver etc for Bitcoin if it acts as a commodity only?
Bitcoin is better than gold. Try to buy some gold today and sell it in a month. When you buy it you have to pay over spot price and when you sell it you get back under spot price, this can be several percentage points, losing more money than just holding inflating USD. Buy bitcoin and sell it in a month, you might pay 0.5% transaction fee at the exchange, or if you are a bit more patient put in a limit order and get it a bit below spot price and sell it a bit above spot price.
