You have 1 million and want to earn 3 million, willing to accept a loss of 500,000. You are optimistic that ETH will rise to 7,000 dollars by the end of 2025. This requires high-risk operations, such as using leverage. You might consider using a portion of your 1 million funds, for example, 500,000, to leverage a larger investment. For instance, you could choose a leverage ratio, such as 5 times leverage, which means you will actually control 2.5 million in funds. If ETH rises to 7,000 dollars, your investment return will be very considerable. But please note, leverage will also amplify losses, so you need to set a profit-taking point, such as selling when ETH reaches a certain price to lock in profits. At the same time, you should also set a stop-loss point, such as selling when ETH drops to a certain price.
