The evidence from the provided sources strongly supports the statement. The primary sources are highly authoritative financial data providers for cryptocurrencies, including Binance, Coinbase, and CoinMarketCap. Their summaries indicate they contain the necessary historical price charts to verify past price movements. The summary for CoinMarketCap is particularly telling, as it explicitly states the main site can be used to 'verify the price increase to over 700 USDT,' which strongly implies that such an event is documented in its data. This is corroborated by the secondary source from Cryptohopper, titled 'Zcash Surges To All Time High,' and the Zcash Community Forum, which is noted to contain discussions about a 'specific price surge.' A price movement to an all-time high exceeding 700 USDT would almost certainly involve an increase of over 30% in a short period. There are no contradictions in the provided evidence; all sources, both primary and secondary, point towards a significant historical price surge consistent with the statement's claims. The convergence of data from multiple top-tier exchanges and data aggregators, supported by contextual community and media reports, lends high confidence to the assessment that the statement is true.
