The evidence strongly supports the truthfulness of the statement, although no single source explicitly confirms the exact value of 12. The reasoning is based on the convergence of several high-authority sources.First, multiple sources are dedicated to tracking historical data for this specific index. CFGI.io is a specialized, high-authority source that directly tracks the 'Bitcoin Fear and Greed Index' over time. Similarly, CryptoRank and MacroMicro provide historical charts for the general 'Crypto Fear & Greed Index', which is heavily weighted by Bitcoin and serves as a reliable proxy.Second, there is direct evidence of the index reaching values very close to 12. A social media post from Cointelegraph, a reputable crypto news outlet, reports the index dropping to 16. Since both 12 and 16 fall into the 'Extreme Fear' category (typically 0-24), this report makes it highly plausible that the index has also reached a value of 12 during periods of intense market downturn.Finally, there is no conflicting evidence among the provided sources. The lower-authority or irrelevant sources (like the Ethereum index, the Solana index, or user-generated content) were disregarded, and all relevant, credible sources point toward the conclusion that the index has historically reached such low levels. The collective weight of the evidence from dedicated historical trackers and reports of similar 'Extreme Fear' values makes the statement highly likely to be true.
