...So you either mine a block and win the jackpot, or get nothing...
Yes.
ThnX! Then maybe I am the only one doing this with S9:) I will leave it couple of days and then go back to mining. I see hopeful remarks about a block expected soon

Lots of hashrate here I have mined 1 year on-off here no luck yet. low hashrate 2.5th though always a chance find that lucky share and change your life..
