Don't forget that, currently some online marketing platforms (Amazon & Ebay), institutions (UNICEF) now accept bitcoin as another mode of payment aside Electronic payment and fiat currency.
Since when did Amazon & eBay accepted bitcoin?
Also, while I think the prices will indeed rise, bitcoin being more scarce isn't itself going to rise the price. Without much buyers and a lot sellers, bitcoin will still continue to drop or be stable in price. Supply is not the only thing that's important here. It's still both supply and demand.
