Disclaimer: This Guide is not financial advice and is not supposed to make decisions for you but is intended to make it easier to understand what Dual Investment product might be suited for you.
1. First, you need to decide if you want to invest into a BTC product or any of the available altcoins. They serve as Underlying Asset for your investment, which means that your return depends on the price action of this asset. Generally said altcoins are more volatile than BTC but APY rates and available products are similar.
2. The second and arguably most important thing you need to decide on is the time frame you are considering for your investment. Currently you can choose between 1 day, 7 days and 14 days.
It is important, because Dual Investment is a product that can not be canceled during subscription and the outcome entirely depends on the Settlement Price on the Delivery Date. What happens during the subscription does not affect the outcome.
3. You need to decide if you want to subscribe to Upward Exercise or Downward Exercise. The following is a simplification, but generally:
Bullish -> Downward Exercise
Bearish -> Upward Exercise
This might sound counterintuitive, but it becomes clearer, when you understand that an execution of a product is negative for you in most cases. It means that your investment gets exchanged to the alternative currency (e.g. USDT for BTC Upward Exercise).
The optimal outcome is to be just below (upward exercise) or above (downward exercise) the Strike Price, so that the product is not exercised, and you get your deposit + yield in the Deposit Currency. Note that in the case of execution, you still get yield.
With Dual Investment you are not exposed to direct market volatility, but are still exposed to big market shifts. Keep in mind that this also largely depends on the chosen time frame.
