Coinbase Premium Index Stays Negative for Ten Days – US Selling Pressure Continues

The assessment is based on two highly authoritative and relevant sources. One primary source, a news article citing the reputable on-chain analytics firm Glassnode, directly states that the Coinbase Premium Index was negative for nine consecutive days. This is extremely close to the claim of ten days and strongly supports the substance of the statement. A second high-authority source from the crypto analytics firm CryptoQuant corroborates this by confirming the index had been in "deep negative territory" for a sustained period, although it does not specify the exact number of days. The minor discrepancy of one day between the most specific source (nine days) and the claim (ten days) could be due to different data cutoff times; it's plausible the streak continued for a tenth day after the data for the article was pulled. The remaining sources are irrelevant as they only describe tools without providing any performance data. Given the strong, consistent evidence from credible sources indicating a prolonged negative period of at least nine days, the statement is very likely to be true.
