Just for my interest. Are there other factors except the amount of coins that you own to find a block (for instance, amount of ingoing and outgoing transactions, the time how long client is online etc)?
Its also based on how many others are forging (the 'generating balance') as well as how many trasnactions are happening (when many trasnactions are happening it lets people produce blocks faster, if no transactions they are slower).
The exact algorithm is a unique invention of the Qora dev and I am not sure if we really understand it fully. It doesnt work the same way as any other coin.
