Last Friday's performance of the BTC spot ETF is worth pondering. Interestingly, if certain information is known in advance by market participants, it could lead to different trading behaviors—while the trend in the first few trading days was quite ordinary, there was a rare net buy-in on Friday. Some investors speculate that this may reflect information asymmetry. After all, before major events occur, only some institutions and media typically have early access to the developments. Whether this abnormal influx of funds on Friday is due to market consensus or some coincidence is still difficult to determine. However, from the perspective of the BTC spot ETF, this wave of net buying indeed broke the previous calm rhythm and warrants ongoing attention to subsequent market reactions.
