When I solved #125 I gave up because it became boring. I thought someone else would solve #130, but nobody did it, so after a year I started again and I spent about two months to solve #130.
Interesting thanks for sharing, I just get a little confused because before you stated that it was more than a year.
3. I have no idea how some people calculated time two months between solving #125 and #130
it was a year or so.
I never said that I spent a year to solve #130, I just said that time between #125 and #130 was about a year, not two months as some people calculated.
Well yes some other users already said that those DP for another rages can help too,my doubt is that if you use them as is or they need some shift/calculation?
It depends on a method used, in my method I can use old DPs easily (just convert all DPs to tames) because my tame kangs are next to zero and their range is small. For classic methods I like this idea:

Not just fishy but VERY fishy. Is this the son of Elon musk or something? We need clarifications from others!!
Why fishy? It makes perfect sense. By solving #120 and especially #125, he had enough BTC, so there was no need to bother further with solving #130 immediately, thus leaving #130 for other people to showcase their skills, but as no one managed to take the opportunity, he came back and solved #130 by himself, not for crypto, but for prestige, and prestige will be even higher once when he solves #135.
Exactly. I'm a retired coder, a good one, so I do it for fun mostly when I have time and interest, and it becomes boring after a month of managing a network of GPUs.

Yes you can use old DPs to solve next puzzle, it helps a bit.
I will try to finish solving #135 in 2025.
Sorry but you are beginning to lose credibility (unfortunately not the first sign).
Let's pretend it took 60 days to solve the 129-bits puzzle, and somehow you were also very lucky and only needed 2**64.5 operations (basically half of the time and lower than your supposed 1.23 factor). Let's also pretend that everything was running 24/7 with no pauses, no interruptions, no overheads from storing and matching DPs, no network congestions, so an ideal scenario.
Let's also pretend that you never needed to compute new starting points (this is the biggest question mark I have on you and your algorithms, since it's unfair not to be taken into account).
2**64.5 = 26,087,635,650,665,564,425 EC point additions
60 days = 5,184,000 seconds
That gives 5,032,337,123,971 EC point additions/sec, from start to solve, in an utopian context.
Let's now pretend your super fast kangaroos runs at 10 Gop/s on a RTX 4090.
This gives a required number of 503 GPU cards, all of them running non-stop 2 months, yielding and sending DPs to a central server.
Let's take something like 0.8 $/h cost of running a single RTX 4090.
The cost of running the GPUs for 60 days at that rate would be 576.000 $.
Until one week ago, you didn't take any profit from earlier puzzles, so clearly this wasn't a reinvestment, and there is strong chance the prize may have been less than the costs.
So, why are you doing this? And I'm not talking about solving the puzzles.
I paid 0.25-0.3$ per hour for 4090. The rest of your calculations is correct (roughly).
I got more than I spent, but mostly I do it for fun and prestige, I like world records
PS. This thread is useless, no tech discussions, 95% are trolls, haters and people with strange ideas, so I will try to avoid/ignore it as I did in the past.
