wow staking has become incredibly difficult over the last few weeks... i have a block of nearly 800 coins with an age of 39 !

Diff has started to stabilize and increase at a steady rate. You should stake soon. In future if you can try for larger block sizes around 3000.
question. At what age might it be worth resizing blocks size 1500 and under? For instance a block of 1200 that is 3 days old might stake faster if I combine it with other to make a block of 3000 (even though I'm resetting the coinage). So for a block of 1500 that is 5 days old, is it worth combining with others or should I just wait until it stakes it to combine with others?
