Thank you very much for this.
In fact, the Lotto ticket is located where we did not enter. In the gaps.
BTCIt took me a long time to find all the gaps.
So choose a ticket. It will take at least 5 years to find it - at least on my machine.

Thanks you too for sharing.

I update my list with your keyspaces, we can do it every month to reduce progressively the unchecked space.
From the last update i've done other 10 sessions (1500 billions keys each).
I hope that other guys excited about solving puzzle 66 will partecipate with their checked keyspaces.
Together we can do in 1-2 years i presume.

I've found in used store the second computer too to use keyhunt randomly to check the gaps (no matter if big, they should decrease in size over time), ryzen7+2080ti.
