I think you mean 2140, not 2040.

Yes. I misread somewhere as 2040. Thanks for correction

The best one could do in an answer is provide a range - because the size of the blockchain depends on the number of *transactions*, not the number of coins. If everybody immediately stopped trading bitcoins and only mined new ones, the blockchain would be much smaller than if every block was so full of transactions that it reached its maximum size.

Size (GB / TB) has nothing to do with the 21 million limit or the year 2140. If you want to know the size of the blockchain in any arbitrary year the best you can do is simply extrapolate. But variables are usage (will bitcoin become popular?) and will the maximum (and average) block size grow? Increasing the maximum block size is being worked hard on by the core developers.

What is the estimated size of complete blockchain when all bitcoins are mined. i.e around 2140?
