I think it may be longer than five years. Seeing as the china ordeal was quite a blow to bitcoin. Some have even said that this de-legitimizes bitcoin. Some have said that the china ordeal has doomed bitcoin to life on the fringes. But this may be offset by the rise of other crypto currencies. Perhaps pressure from rising use of these currencies will make amazon and other shops relent. I saw that google has invested in some other cryptos like ripple, say it may be that they will accept such currencies for use on amazon play. Come to think of it, I kind of think that online subscription services/download services like itunes, or ultraviolet, or amazon prime instant video, netflix, would also jump on the bandwagon. Here we are trading digital services/goods for digital currency, as opposed to digital currency for phyisical goods. Its sounds neat though not necessarily cheaper. Maybe beginning with smaller shops and their adoption will lead to bigger online retailers accepting cryptos.
But the way forward some have said would be to drive greater adoption. What are the safeguards for cryptos against inflation, if any? Im new to all this.
