The assessment is based on a strong consensus among multiple high-authority primary sources. Several sources provide direct, quantitative evidence that Bitcoin's price has not only reached but significantly surpassed $87,000. For instance, CoinMarketCap's dedicated Bitcoin page shows a live price of $91,296.53. This is corroborated by price tickers on other CoinMarketCap pages, which list Bitcoin's price at $88,820.61 and $90,560.44. Furthermore, Coinbase, a major exchange, suggests an all-time high well above the value in the statement. The evidence is consistent across all relevant sources, with no contradictions found. Other provided sources, like Yahoo Finance and Investing.com, are established platforms for verifying such historical financial data, which adds to the confidence in the claim's verifiability. The irrelevant sources concerning other assets (Bitcoin SV, Shiba Inu, Copper) were correctly disregarded.
