So...anyone with even a 13.5th S9 has a chance at getting a block! In regards to the diff for 10k or 1M, I didn't clearly understand...does that mean 1M diff port is better than the standard port? Please clarify! Thanks.
It does not really Matter.
10k is starting diff, it goes higher or lower depending on your device and connection.
1M is the diff for rentals like nicehash but you also can run your s9 on the 1M port.
Luck will be the same. Always. Luck is proportional to hashrate.
Just imagine a connection that sends packages of 10k or 1M.
So you have 100x10k or 1x1M packages. Which connection is faster?
