anon9575: move a few things around flip a few codes now youre processing sha256 but not the way us miners use it for
anon9575: now you have the secret code behind bitcoin 1
anon9575: now you manipulate that not to get more bitcoin but to generate wallets

anon9575: the wallets have a chance to repeat already generated wallets
anon9575: woah youre saying two wallets with the same recieving address????
anon9575: yes
anon9575: i counterfiet
anon9575: a not i

For anyone not sure why this is not a brilliant idea:

Generating a wallet address DOES have a chance to 'repeat already generated wallets'... The problem only comes in when you actually look at what that chance actually is.
What you're looking for is a RIPEMD160(SHA256(SHA256())) collision. There are around 2^160 possible wallet addresses. To put that into perspective I believe the number of atoms in the observable universe, is estimated to be between 4×10^79 and 4×10^81
What does 2^160 look like?
approx: 1,460,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
