I just got the following thought.
you didn't explain what your thought exactly is!
If you would find a wallet
what does this mean, you mean searching the internet or other people's computer to find their wallets.
or do you mean finding (creating bitcoin addresses) because a bitcoin wallet is file that is holding the bitcoin addresses + their private keys that your wallet application has created.
that could hold all bitcoin addresses incl. there Private Keys,
you have to create all those addresses + private keys and since there is
2^160 possible bitcoin addresses you will have to continue making addresses until the end of the world.
you should have all available Bitcoins in your wallet, or am I wrong? (It's just a theory)
yes you are wrong.
