Bitcoin users frequently generate new addresses for each transaction they make, which greatly increases the number of bitcoin addresses being used to receive money.
Would it be possible (and profitable) for someone to find collisions in the bitcoin address space in order to steal money?
"Is it possible to brute force bitcoin address"
Yes. This has already been done.
No, it is not possible and it has never been done and RawDog is our local forum troll, so you should take anything he says with a pinch of Salt.
A bunch of people have generated a websites on the internet, with a so-called database of all Bitcoin addresses and they telling everyone that there are collisions on the website. This is just a joke.
