Re: List of all Bitcoin addresses with a balance [back online)
I spent nearly a year, reading and writing over 888 billion (888000000000) private keys, generating corresponding public keys of various types for comparison ("hack" Bitcoins).
Why so few keys? I'd expect decent hardware to check hundreds of millions of keys per second.Quote
But the result is nothing except electricity bills.
At least you've proven to yourself that Bitcoin is secure

Also, I'm certain that many people are doing similar things, especially those with special addresses that are constantly being monitored.
Thanks to Full RBF, the competition for those addresses burns almost all funds as transaction fees, and leaves only dust amounts to be taken.
