Will someday bitcoin address will be run out ?
It's possible but in few thousand years ahead !
When I see a legendary member saying something like I'm speechless. Seriously?
Did you bother to read what o_e_l_e_o explained just 3 posts above?
You are underestimating by just a touch. Our best estimates are that since modern humans first evolved 50,000 years ago, there have been around 110 billion of us on the planet. That means that every human that has ever lived could have started using a trillion new bitcoin addresses every second of every day of every year for the last 50,000 years, and we would have so far used 1.73*1035 addresses, which is somewhere in the region of 0.00000000001% of all possible addresses.
If bitcoin addresses would run out in a few thousand years, at a rate let's say of 3 uses per persons per day and a population of 10 billion, then the Large Bitcoin Collider would have already guessed about half of the privkeys.
