There are 21 million Bitcoins and nothing more. There are 17.2 million Bitcoins in existence. There are 3.8 million Bitcoins left. How much will the last 100 bitcoins sell for?
We can't easily figure out that what price will be of the last 100 bitcoin because value of 1 bitcoin doesn't totally depends upon the mining difficulty , here 1 BTC value goes to $23k/BTC and now it is less that $8k/BTC , so here we can easily expect that there is totally unexpected price exists .
Here demand of bitcoin to buy and sell is a big part of the crediting value for the bitcoin , so here clearly we only expect average the procieof the bitcoin by calculating the progress of 9 years .
But what I think and my mind making the prediction about the value of the bitcoin is $100k/BTC will be very less because after nine or every 1 BTC , the difficulty to mine next bitcoin increases , so clearly it will not be easy for miners to mine whole bitcoin in few years , may be it will take about 20 years to complete mine of 21 million bitcoin .
Here everything is my prediction and expectations , that I deserve for the bitcoin , and that can be different for different person .
