In the case of currency, it is in each individual's best interest to use the most liquid, most widely used and most stable currencies. In crypto the assets that best meet these requirements have been dollar-denominated stablecoins. The ‘common goal’ in this context, is to maintain the individual’s purchasing power. This is something which stablecoins categorically do not achieve as most of them are pegged to fiat currencies, which are exposed to inflation risk. No individual acting alone can disentangle crypto from fiat. It takes mass coordination and alignment of incentives and this is what Olympus facilitates.
