I am mining with almost 3MH/s of GPU for over 1 hour! But I have 0 confirmed and 0 unconfirmed doges... Is that normal??? This is what I can see on the top right of my screen...
Est. Shares 993428 (done: 195.89%)
Pool Valid 1945985
Your Valid 14976
Pool Invalid 67709
Your Invalid 333
Yes its fairly normal, just means your pool hasn't found a block in that time. Keep mining and you'll be paid based on the amount of shares you earn't, these are given out based on the block work you do and how long you are doing it for

When a block comes through you'll get a chunk of doge
What would happen if i closed the CGMiner before it finds the block ?? Would I just not get paid at all ?
