Maximizing the profit margin for a trade varies entirely depending on the preferred financial product. For example, let's assume there is a 5% increase in ETH/USD parity. This means that you will earn 5% in USD (excluding commissions). If there is a 5% increase in the BTC/USD parity, the ETH/BTC parity will remain at almost the same price since both of them increase at the same rate. The only way to gain more than 5% using the ETH/BTC parity is with an increase below 5% in the BTC/USD parity. That is, it will be possible to earn more profits depending on the unit of the preferred parity.

Another possibility is to evaluate the mobility in the ETH/BTC parity and obtain a profit margin on Bitcoin basis. In this way, since the profit will be earned in Bitcoin it will be possible to earn profit with the increases in Bitcoin price. For example, let's assume that 1 Bitcoin is gained with ETH/BTC parity. At this point, if there is a 10% increase in the Bitcoin price an extra 10% gain in USD will be obtained. In other words, in order to maximize the profit margin by trading with ETH/BTC parity both Ethereum must gain more value compared to Bitcoin and Bitcoin must gain value on a USD basis.

In summary, there is always the potential to earn more profits depending on the preferred transaction parity but if a parity such as ETH/BTC is preferred both Ethereum and Bitcoin must gain value on a USD basis in order to maximize the profit margin. Additionally, the fact that Ethereum has gained more value compared to Bitcoin is also important in order to gain maximum profit from this parity.
