The assessment is primarily based on a single, highly authoritative and relevant source. CoinGecko is a top-tier cryptocurrency data aggregator, and its confirmation that the Solana-based meme coin COPPERINUS surpassed a $12 million market cap provides strong evidence for the core of the statement. This directly supports the valuation part of the claim. The other two sources are entirely irrelevant to the topic and can be disregarded as they offer no supporting or contradictory information. While the specific multiplier of 'over 210 times' is not explicitly confirmed by the provided text, a massive increase in value is a necessary and highly plausible precondition for a new meme coin to reach a multi-million dollar valuation. The confirmation of the $12 million market cap from a credible source makes the overall statement very likely to be true. The small degree of uncertainty stems only from the lack of direct verification for the exact multiplication factor.
