Hello viatorek, good morning! As I wrote yesterday, my earnings dropped sharply to about one third. I know the difficulty increased and yesterday there were problems, maybe coincidence, bad weather, ghost in the machine... I do not know, but the difference is too large and it does not look that today will be better! I suspect that not all the work is really credited. There are many blocks on which I worked, but in the list of transactions are not listed. For small example, for blocks 64365, 64366, 64370, 64376, 64378, 64380 I got nothing.

In other words, I have credited only a few blocks per hour, sometimes only one or even none! How is this possible?
that is normal that you work on every block.
your miners mine at block 64364 and then they found the block, you got coins for it but if like 64365 was a very small block you maybe don't work at that one, have that problem to because my miners are really slow.
total of 120-140kH/s
my earnings are now at 500 doge a day with this diff, few days ago did I do 2K but diff was 200-300
