I often use OKX's dual coin win as an auxiliary tool to execute the bottom buying strategy according to the plan, and its biggest feature is its flexible timing. By comparison, returns at the same execution price and time slot are also more competitive. For example, I originally planned to establish some long-term BTC positions in the 5.6w to 5w range. So, I can use OKX's "buy BTC low" strategy to find the closest time to now, select the corresponding execution price, such as $56000, $55000, and $54000, and enter the planned purchase amount (equivalent to placing orders in batches). So by tomorrow afternoon at 4:00 pm, if the BTC price is lower than the above strike price, the system will buy BTC at the corresponding price (the profit will also be settled in BTC); If the price is higher than the strike price, the system will refund USDT and interest. Simply put, if I didn't buy it, I earned interest; If I buy it, it perfectly fits my original plan. Usually, I would not choose a date that is too far away from the current execution date, because I want to ensure flexibility to avoid the awkward situation of "the price has already arrived before the time is up, and when the time is up, the price has gone up again", which may disrupt the pace of building a warehouse. Of course, you can also allocate funds and plan your time according to your own plan, while also considering the return rate. Try different combinations and find the most suitable strategy.
