You can find bitcoin prices easily for any date in history since the beginning of trading in July of 2010. Typically price quotes will be available for any specified date with an opening, closing, high and low price for that particular date. However with Bitcoin pricing various traders have requirements to know the price as of a particular point in time. This is because sites like 'lbc' or 'paxful' allow for individuals to trade with others by supplying the escrow and rating services so unknown participants can engage in transactions somewhat securely. As a trader you can set the desired 'markup' percentage from the bitcoin price the platform is calculating. Say for example you set you desired sales price to BTC price + 3%. You should make 3% - fees. When you sell the BTC the platform records the sales price and the funds are transferred directly to you buy the buyer. What was your actual profit? Was the price set by the platform in line with other prices. What would be nice to know is what were other prices around that point in time so you can somewhat look at what profit you made with the 3% (or whatever) markup.

Often trading bitcoin involves buying at one price and selling at another. You may be a 'market maker' or just a speculator. But one thing is for sure, if you are 'flipping' bitcoin you will eventually need to come back to this --> 'What was the market price when I sold?'. True of stocks also? Not so much, bitcoin is somewhat unique as with stocks the market price is already saved and available. Your 'total gain' is one thing, but do you know the 'flip' side of the coin?
