The beta version of this tool is ready. Those interested can test it out. Here's a brief overview of its features: 1. Enter the funds you want to invest. These funds must already be in your @binance account. If the settlement is successful at maturity, after deducting any losses, it will directly buy bitcoin:native spot, enabling you to buy at the bottom. 2. Enter the price you want to sell and put at. Think of this as the price you want to buy Bitcoin at at the bottom. If the price reaches or falls below this level at settlement, you will receive Bitcoin spot. If it's higher, you will receive the premium, or interest. 3. Select an expiration date. You cannot end or cancel before the expiration date. After the transaction, the funds will automatically go into your Binance options account. This tool doesn't handle the transaction; it's entirely your own API. It's recommended to try it with a sub-account. 4. Settlement upon maturity: For example, if you have $80,000 to buy BTC at $78,000 for 3 days, then at 4 PM Beijing time after 3 days, if the price of Bitcoin is below $78,000, you will buy spot BTC at $78,000 (minus any potential losses). If it's above $78,000, you will receive the premium, which is essentially interest. 5. I've compared the returns of SELL PUT and Binance dual-currency investment. If the difference is small, using dual-currency investment is more convenient. In summary, this is an automated SELL PUT Bitcoin investment function that converts to spot buying at the bottom, all done on Binance through its own API.
