Bitcoin was _never_ about speculation, and it was never intended as a store of value. However, it was designed to be deflationary in nature due to having a maximum of coins ever mined, or, more strictly, cutting down the rewards to half every 210k blocks mined).
And if I had to choose (which I don't, as I save in USD), I'd still prefer saving in BTC than in my local currency.
People living in thirld-world countries understand this.
