Well, it doesn't work like this. Producers of goods and services have no obligation to sell a fixed amount of goods and services for a certain price in the future. You have a choice to consume now or to save and consume later, and there's an inherent risk to saving because the future is uncertain. And this is true regardless of the currency that you use, or the inflation rate. A crypto-currency is not going to make the future any less uncertain, sorry. You have been sold a lie. In fact, if you put your savings in a crypto-currency, saving is going to get a lot more risky for you personally, not less.
