The evidence from multiple relevant and authoritative sources strongly supports the statement. There is a broad consensus that a rapid price drop, described as a "plunge" or "flash crash," did occur. High-authority sources like CoinDesk, and financial commentators like the Schwab Network and The Kobeissi Letter, all confirm that Bitcoin's price fell sharply to the $84,000 range or below. While these sources establish the general event, they do not specify if the price went below $82,000. However, the Tampa Free Press article directly corroborates the most specific part of the claim, stating that Bitcoin tumbled to a "harrowing low of $81,000." This directly supports the assertion that the price went below $82,000. No source contradicts this specific low, and the other reports of a crash to the low-$80k range make it highly plausible. The Coinbase source, while being the ultimate primary source for price, does not provide a specific data point in its summary but its existence as a record-keeper lends credibility to the event being verifiable. The irrelevant sources concerning other assets (Pi, Ripple, Gold) were disregarded. The collective evidence paints a consistent picture of a major price drop, with one source providing the specific detail that validates the statement.
