A recent report analyzed the different paths of BTC and ETH to "currency", and the report said it depends on how they define "currency". The report writes: “Bitcoin ’s approach is to focus on consolidating the monetary base, while Ethereum ’s approach is to focus on further monetary aggregates.” The figure shows that BTC first focuses on the monetary base, while ETH mainly focuses on the currency utility. Looking at it, BTC and ETH do have the ability to become the world's first digital currency without any government intervention. If BTC survives its "hard-coded monetary policy", Ethereum can prove that it can monetize on the basis of changing currencies. The upcoming ETH 2.0 upgrade may also increase the future profitability of ETH. The report concluded that both Bitcoin and Ethereum must create a certain amount of circular economy without having to rely on fiat currency: "This is especially true for Bitcoin. In order to establish its own future monetary base, its users need to start thinking Use Bitcoin / satoshi as a natural account unit. "
