#美国就业数据表现强劲超出预期 Entering the second half of December, Bitcoin is facing pressure — the 90,000 level is teetering on the edge. Tomorrow, the Bank of Japan is very likely to raise interest rates, planning to increase by 25 basis points. Looking back at historical records, a pattern emerges: whenever Japan raises interest rates, Bitcoin tends to decline in the following weeks, and there are no exceptions to this rule. Over the next two months, if Bitcoin still cannot recover the 100,000 level, then the bear market next year will be virtually certain. The old theory of a four-year bull and bear cycle still seems to hold. The future of $BTC and $ETH depends crucially on whether this time window can be maintained.
