My cousin asked me what is my prediction for Bitcoin's value...

"

Value is determined by what it is...

In the end, when it is universally preferred by everyone for receiving payment, inevitable, then Bitcoin's total value will be whatever value in total there is in the world, as in the value of all the stuff that can be bought , which is 2.1 quadrillion US dollars approximately.

*The total money value equals the total world value*

Because there are 21 million coins in the total of the money, then divide the total world value by the total number of coins.

2.1 quadrillion divided by 21 million coins... $100M value for each coin.

Many coins are lost, so it should be even higher.

Then, with well functioning money, humanity becomes much more productive, so total value in the world keeps going up, so purchasing power, value, of money keeps going up even after that price prediction, but slower.

Right now the price is low because it's still becoming adopted as money by people, and that path is choppy and not finely predictable, but the end is predictable.
