The evidence provided strongly supports the truthfulness of the statement. The sources create a cohesive and logical narrative. The summaries of the CoinMarketCap and MEXC sources indicate they are primary, authoritative data feeds that can be used to verify the exact price movement of WHITEWHALE within a 24-hour period. While they don't state the specific percentage in the summary, they are the definitive sources for such a claim.Crucially, the announcements from the official Bybit exchange accounts on X and Facebook provide a powerful catalyst for such a dramatic price increase. A new token listing on a major exchange like Bybit, especially when coupled with a promotional trading event, is a well-established reason for significant and rapid price appreciation. This provides a strong 'why' behind the claimed 85.84% increase.Finally, the news article about trading accusations on MEXC, while potentially negative, corroborates the idea of extreme price volatility surrounding the token's launch, which is consistent with a massive price swing. There are no contradictions among the sources; instead, they collectively paint a picture of a high-volatility event driven by a major exchange listing, making the specific claim of an 85.84% increase highly plausible.
