It's more of a speculation topic and there's nobody that has a proper idea on how much bitcoin would be worth by that time.
Maybe $1,000,000
But it can be $100
This means one thing,we cannot really tell what will be the value after 6 years from now,but i am confident that we will grow higher conpared to what we are having now
We can't be sure about it.
Predictions by that time says that bitcoin can go higher than $100,000.
