What to do now? it's on 100 %

What does it mean that this is on 100 %? I'm mining Dogecoin with Cudaminer

 What do i do now? 

I've stopped it multible times to game, and it starts on 100 again

What exactly is 100%?

I don't know.. That is what i want to know :)


This is how it starts


You mean, the block is at 100%?

That means the block is 100% mined, but there's no other block yed discovered to mine, so you are mining a full mined block.
