$ETH 4270 is very critical; it is basically the limit of short-term market adjustments. If it continues to drop, it will head towards 4000. If it effectively breaks below 4000, it would technically be somewhat damaging to the trend. From a structural perspective, it would be better to adjust to 4000, and even a small dip below 4000 followed by a quick recovery would be ideal, but it can only be a spike, not an actual bearish candle closing below 4000. The eth/btc exchange rate has also reached the lower edge of critical support, and all institutional quant strategies are short. I still hope that the adjustment to this point will be sufficient.
