He is asking you for your fundamental analysis on BTC.
Here's my take on the fundamentals. Let me know if I've missed anything.
Bitcoin Fundamentals.
Bitcoin doesn't exist. It's virtual.
Definition of virtual
-Existing in the mind, especially as a product of the imagination.
-Created by computer technology and appearing to exist
It's a series of ones and zeros on a computer. Without a computer there is no bitcoin.
Bitcoin comes into virtual existence as a reward for solving a problem. Problems get more difficult as bitcoin approaches its max number.
Bitcoin has a limited supply. 21 million max. (Rumored that 4 million are already lost)
Bitcoin is secure. So secure that if you lose your key the coin is gone forever. Over time this should reduce the supply.
Bitcoin is decentralized. No one controls it. It can be moved from country to country with ease. It is free from government manipulation. However I do believe that there is some control over the internet.
Bitcoin can be used as a medium of exchange. Easily divisible to allow for small transactions. It is becoming accepted at more and more merchants who are converting it to fiat before accepting it. Merchants have yet to price items in bitcoin.
Bitcoins value in fiat currency is what ever you can negotiate. If you want to exchange your bitcoin for fiat or merchandise you have to find someone willing to take it off your hands.
The value of bitcoin (in fiat) is very volatile. Depending on who you listen to it may be worth millions or nothing in the future.
