The recent actions by China Construction Bank carry significant signaling meaning. From an on-chain regulatory perspective, this is not an isolated incident—it reflects a systematic tightening of attitudes among mainland financial institutions toward virtual currency transactions.

Let's break down the key points: First, the recognition mechanism has already been deployed, and triggering risk control through transfer remarks has become routine; second, the execution logic is ambiguous—the question of "how to prove that remarks are unrelated" exposes the inherent vagueness of regulatory rules themselves, leaving considerable discretion for frontline bank operations; third, the cost of expectation management is rising, as users need to submit multiple layers of proof to lift account restrictions, which effectively increases participation costs.

From the perspective of capital flow, such policy orientations will directly suppress the activity of domestic over-the-counter (OTC) trading. Once user transfer paths are restricted, on-chain fund inflows through domestic channels will be forced to shift to other methods or shrink outright.

In the short term, this will strengthen hedging sentiment in the crypto market, but in the long term, it is more worth noting whether similar policy coordination will be promoted in other regions or banking systems. Systematic tightening of regulatory attitudes is rarely an isolated action by a single bank.
