[Matrixport: Sustainability of Bitcoin Rebound Requires Validation from Macro and Capital Dynamics] Matrixport pointed out in its latest analysis that the current Bitcoin pullback has approached a cost-effective range, with the RSI indicator recently dipping to 35, indicating that technical buying activity tends to become active near this level. However, the sustainability of the rebound still requires validation from macro catalysts. In the short term, the U.S. government shutdown issue may be resolved this week, and Trump’s mention of issuing approximately $2,000 'stimulus checks' to the public has sparked market associations with the retail frenzy of 2020-2021. Nevertheless, against the backdrop of ETF net outflows and institutional investors' temporary wait-and-see stance over the past week, the current rebound momentum remains limited. The aforementioned catalysts alone are unlikely to drive a trend reversal, and support from both capital dynamics and fundamentals is still needed.
