eth: Today resistance is 3272, support is 3150 (the needle part is 3142). If it breaks below 3150 in the short term, the decline will expand. The amplitude is shrinking and organizing to the right. The potential for a rebound at the 2-day level is strengthening, with strong resistance between 3372-3440. It will only reach 3495-3555 after breaking through.

Therefore, bears defend at 3450, while bulls defend at 3140.
