I think you might see how impossible this is, after you watched this video : https://www.youtube.com/watch?v=ZloHVKk7DHk < The math behind this is mind blowing to say the least >

I am not saying it is impossible, but looking at the math, I can quite confidently say I am 99.9999% sure that it would not happen.

In a scenario like this, both people with the same private key would be able to spend the coins.

You don't get access to all the private keys of the Bitcoin addresses on a centralized exchange. These exchanges alone have access to your private keys. The possibility of your address been previously used is there but I don't think it's happening.

If your Bitcoin address is already in use, then you'll have access to its past transactions on the blockchain. Just check to confirm. Don't forget that the blockchain is A PUBLIC LEDGER THAT CONTAINS THE DETAILS OF ALL PAST AND PRESENT TRANSACTIONS.

Yes. It can happen. There is no mechanism that prevents this from happening in an infinite time space. In fact, more than a private key can correspond to a single address. If that ever happens, then all of them can be used to spend the funds in that address.

The probability is not just low, its incredibly low if your wallet has a functional random number generator.

So, I had this question in my mind for a little time and now I think I really need an answer.
If you create a btc address you get the private key of that address, what if this address is already in use ?
I know there is a really low probability but this can happen, am I right ?
