Still new and learning here but Im curious...
What would be in a block that takes a pool with 1.631 Eh/s, 6 or even 9 hours to complete? Some blocks go really quick while others seem to take forever... so is it the amount of work to be done? That the pool hasnt found a new block to work on? A combination?
Just wondering.
Its called "Luck". Keep an eye on that number on your dashboard page.
Slush had terrible luck today. 2 blocks in about 16 hours.
Finding blocks is not a regular occurrence. Its a highly random process.
