How much fiat will it take to get us to $3k?
somewhere around 47-48 billion dollars in market cap for 15.700.000 - 15.800.000 coins.
But you can find out by basically multiplying 3000$ x [number of coins] = market cap .... but that is not exactly necessarily! ... Because if the markets want 2000$ for 1
BTC ... then they will keep that price with less money in the system or more money in the system. Meaning supply&demand rules do not always apply! ...
Meaning someone will make someone else lose money or coins for the love of speculation.Basically there can be 20 billion in the system but only 10 billion are accounted. Also the exchanges bleed an amount of the user's fiat with the transaction fees.
Mostly it is a very emotional process setting the price. And example would be if there are only 19 million
BTC in the system and 17 million are not transactioned ... that created a limit of 2 million coins for that 20 billion $ in the system. So you will do that 20.000.000.000 $ (divided by) / 2.000.000
BTC (coins) = [value per coin] 10.000$ ... if only 2 million coins are used in a 20 billion $ market cap ..
Does this help you understand better in the future so you can calculate on your own?
