Kay Van-Petersen, who predicted last December that the Bitcoin price would rise to $2,000 in 2017 (it was $754 at the time), used the following rational to calculate potential price of Bitcoin in 10 years:
Average daily volumes (ADV) of foreign currency exchange is currently just over $5 trillion (according to the Bank for International Settlements).
Cryptocurrencies could account for 10%, or $500 billion of that ADV in 10 years.
Ten percent of $5 trillion is $500 billion.
Bitcoin could have 35% of the cryptocurrency share of ADV – or $175 billion.
Market capitalization to support $175 billion daily exchange would be $1.75 trillion (10X times the average daily volume).
Divide $1.75 trillion by the projected 17 million Bitcoins expected to be in circulation 10 years from now and you arrive a price of just over $100,000.
