All currencies are prone to manipulation. Spend a couple of months trading forex (even on paper) if you don't believe me. The columes involved in forex trading (last I looked something like 3 or 4 trillion USD/day equivalent) are way beyond the capacities of /any/ central bank to "manage" or manipulate in their own favour, and it's an over-the-counter trading system, so mostly-impossible to regulate.
