While speaking of Bitcoin rates on the exact date, you should always keep in mind that this is a median rate, calculated as the average price on the market. This is the sort of information provided by multiple platforms, such as CoinMarketCap. However, the rate dynamics is much more complicated than that. The average price you can look up represents a general tendency, and cannot be guaranteed for your particular purchase. This is the peculiarity of crypto that makes it closer to stock markets rather than traditional fiat currencies like euro or dollar – the price of BTC or any other crypto can fluctuate every moment, depending on the market situation.
