Can you give example on how to calculate marketcap? And how supply is counted?
if you're asking about supply in regards to the price of a single bitcoin.
you have to check the supply of bitcoins on the order line of the exchange you are look at the price of...
each exchange has its own supply of coins in reserve and each exchange has its own bitcoin price
if you are asking about the market cap $ statistic.
this is an ESTIMATE statistic based on whatever site your looking at getting an average bitcoin price from multiple exchanges. and then multiplying that average by the total coins ever created.
the $$ market cap is a statistic.. it is not a true value. there is no billions of dollars attached to all the coins in existence.
the $ market cap and the exchange price are two separate things.
the $ market cap statistic is an after thought and not important
Many thank's for this clear answer.
