I think we can think about it after hundreds of years Cheesy

The available adresses are uncountable

after some thousands of years if an alien civilization with thousands of quatrillions of inhabitants invades earth and adopts BTC as official currency.

if such scenario would be feasible even after thousands of years, I think most of addresses would have been bruteforced by now

I don't think that it will be going to happen.

You might be careful with posting in multiple threads with very small posts that don't add much and having something in signature, it's kinda asking for a ban.

If anyone want's to see how many wallets there just try to do a vanity address. You will see how many address's you generate if you are using GPU's. And getting one depending on how many variables can be very very hard.

I use cold address's and sleep safe at night not worried about someone getting my address.

Vanity addresses are largely dependant on luck. Even though math says it's 1 day, it might just take 1 hour or 1 week. If a collision does happen, your cold wallet won't save you. It could also be compromised if the RNG used is weak.

It is my understanding that bitcoin wallets are created through a hash table with 64 bits of alphanumeric characters. What happens when all wallets are completely used up? What happens then? Just a curiosity question.

is practically impossible, there may be only after thousand years

The Landauer limit is a theoretical limit of energy consumption of a computation. It holds that on a system that is logically irreversible (bits do not reset themselves back to 0 from 1), a change in the value of a bit requires an entropy increase according to kTln2, where k is the Boltzmann constant, T is the temperature of the circuit in kelvins and ln2 is the natural log(2).

If someone want to do the math...

I think that's unlikely. The amount of energy needed would be huge, even with the most advanced computing.

I believe the op didnt mean what if we now exploit and use up all addresses, but rather in future, since we all imagine that bitcoin will still exist then.
With advancement of technology, i ackgnowledge the scenario where it is possible for some advanced computing to create this problem.
But what u fail to realise is that bitcoin will also advance, and will walk around any issue we may have, and for now its impossible for that to be a problem

cheers

No advnced computers can bring up such a problem as of now

Read what i wrote before commenting please. I did not say that there can be problems with this issue now.
I said that in the future (you you know how fast computer industry is evolving?) its quite possible that some issues like this may come to light.
Ofc, bitcoin will adapt and counter anything that prooves itself to be a problem, nothing is hard-coded. (xcept 21 mill coins limit)

cheers

Based on the Moore's law, computer's speed will not double anymore after at most 2020 which it would then grow at a slower rate. I don't see this happening in the future since it would require a lot of power and cooling if such a machine is built.

You can change anything in the protocol if you do a fork but that would require everyone in the network to switch to the version you created. You can technically change the 21million BTC limit or anything else but the whole network needs to agree or a fork will happen.

It will be exciting to see if Moore was right or not. I tihnk he isn't right tho.. we'll see technology still doubling for a while.

So, I reuse an address, and then the other person with that private key scoops out my coins?

Not like there is the remotest possibility of that happening, but...

It is practically impossible for one to generate all the addresses available without a few thousand hardware from the future (few hundred years). Why would someone even want to try it? It would just be a waste of resources.

If I were you I won't be bothered at all as the possibility is so low. Too low, like almost zero probability to have the same address owned by two different person. Even in advancement in computing power for years to come it will take a whole lifetime for things like that to happen.

There are too many bitcoin addresses that can be generated. Generating them all requires a computing power that's never been heard of before, and can be possibly invented after millions of years from now. It is possible, but is very improbable at the current time frame.

I guess you are talking about bitcoin addresses and not wallets. Given the number of addresses possible, it is unlikely to happen when mankind rules.

There are so many addresses that the probability of an identical address being generated by 2 users is almost zero. That should happen long before all addresses are used up.

In all likelihood the universe will have ended thousands billions of years before anyone (or any group) could generate them all.

And if they did in some alternate reality with different laws of physics, they'd just be reused.

If it ever looked like it was a physical possibility, doubling the length would change that.
