My point is that the notion of a "real" interest rate as defined doesn't exist. The idea of a currency that cannot be manipulated is a chimera. Here are two reasons: 1. Currencies are created by some government or government-equivalent (e.g., maintainers of bitcoin/bitcoin fork), and these governors set the supply of currency. Sometimes they use interest rates, sometimes they just print more currency, sometimes they set a schedule for mining digital currency, it doesn't matter. However, the "free market" is inherently manipulated by the "owner" or "creator" of the currency. 2. If you consider a "commodity-currency" like gold or diamonds (or probably bitcoins) whose supply is not determined by a central authority, these commodity-currencies can also be manipulated. In fact, without the check of a government, capitalism works in such a way that these commodities become centralized into a few large holders who are incentivized to manipulate the currency. This is why governments like to get off of the gold standard, so they can manipulate their currency without interference from other governments.
