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 ?

Here's another website that has your private key: https://lbc.cryptoguru.org/dio/1

However, it may take you a little while to find it on there, since it says at the top of the page:

Page 1 out of 904625697166532776746648320380374280100293470930272690489102837043110636675

This website doesn't actually have 904625697166532776746648320380374280100293470930272690489102837043110636675 pages stored to disk, as that would take up quite a bit of space. Instead, it produces the pages on demand as you flip through them. You can also change the "/1" in the URL above to "/[any number between 1 and 904625697166532776746648320380374280100293470930272690489102837043110636675]" to go directly to that page. Though I must admit, I haven't tried them all.

As you can see, the chances are so small that someone else would have your private key. In fact, it's extremely likely to take billions of years to find it.

But, of course, the first guess could be right! Just extremely improbable. So improbable that it's hard to imagine just how unlikely that would be.

A Bitcoin private key is safer than the safest lock in the world. It is so safe that people have trusted hundreds of billions of dollars in Bitcoin to the security of the public address/private key combination. Many altcoins use the same method for their addressing, though the namespace may differ, so people storing other coins, such as Litecoin, have also trusted this system for addresses and private keys.

Fun fact I discovered while searching around looking for analogies for this reply. Did you know that a piece of paper folded 103 times is as thick as the Universe? I didn't!

Happy hunting!
