The safe boundary of BTC fixed investment cost Fixed investment is a "foolproof" practical strategy that many people adopt, which is easy to psychologically build and can reduce holding anxiety. But when BTC rebounds from 6w to 8w, do we still need to stick to fixed investment? What is the safe range to control costs? Today we will talk about this topic. In the previous tweet, we summarized that whenever the "investor confidence index" falls "underwater", it enters a bear market; Return to the water and step out of the deep bear. We assume that starting from 'entering a bear market' and ending with 'emerging from a deep bear market', we will make a fixed investment. So, after reviewing the past three cycles, the following data were obtained respectively ： one ⃣ Fixed investment period: February 3, 2018 to April 2, 2019 Total days: 423 days; Maximum buying price: $11480; Minimum buying price: $3242; The average cost of regular investment is approximately $6420; The final bull market high point is $69000; two ⃣ Fixed investment period: December 11, 2021 to March 17, 2023 Total days: 402 days; Maximum buying price: $50803; Minimum purchase price: $15599; The average cost of regular investment is approximately $27350; The final bull market high point is $126000; three ⃣ Fixed investment period: May 21-2026.5.12, 2025 Total days: 203 days; Maximum buying price: $103450; Minimum buying price: $62180; The average cost of regular investment is approximately $81650; What is the final bull market high point??????; Therefore, we can understand it as follows: Assuming someone persists in buying during the most panicked 203 days in this market, their average cost now is roughly around $81000. And as long as your Heisei cost is not higher than this price, looking at it for a long time, it can be said to be absolutely safe. Of course, if possible, the lower the better. Because the market cannot always be in a state of 'panic'; When entering an optimistic mood, the pricing of BTC will definitely be higher than the average cost price during the panic period. Leave the rest to time, time will not disappoint us!
