According to @rovercrc, a single chart compares Bitcoin’s 2021 and 2025 tops and highlights that the structures differ rather than match one-to-one (source: @rovercrc on X, Aug 13, 2025). The post is framed for trading use, indicating that differing top structures can affect BTC exit timing, profit-taking, and risk control assumptions (source: @rovercrc on X, Aug 13, 2025). The emphasis on difference cautions traders against mirroring the 2021 template for 2025 BTC decision-making (source: @rovercrc on X, Aug 13, 2025).
