WOOT! HAPPY $50K DAY! WOOT!

BitCoin BTC hit a price over $50K briefly today, 16 FEB 2021, in the early AM (US time zones). A reason to celebrate a snowy day!

edit...

Fixed the issue, used the wrong port on the pool with the "correct parameters"...

Code:

cpuminer-zen3.exe -a yespower --param-key "CPUpower: The number of CPU working or available for proof-of-work mining" --param-n 2048 --param-r 32 -o stratum+tcp://eu.blockmasters.co:4250 -u -p c=

Does this support 'cpupower' in it's current state? (CPUchain Core)

Code:

PoW Mining Algorithm: yespower / 'cpupower' with N = 2048, r = 32 and perslen = 73

I tried the 'yespower' algorithm and got rejects spammed for to low difficulty on the hash.
I suppose it's not correct. A variant with these variables needed?

It looks like once you find 10-12 blocks in solo mining, the periodic hash rate starts to even out. It’s hard with Minotaur because blocks don’t come that often, unlike pool mining where shares are 3-4 per minute.

You still around lcc/ring?

Can you add new BALLOON algo for Zentoshi.
From https://github.com/zentoshi/cpuminer-opt-balloon
have trouble creating win EXE.
THX

It's only for one coin that isn't listed on any exchanges, so I'm not interested.
Zentoshi should provide Windows EXEs for mining.

Just tried this out for the first time, wanted to say THANKS for doing this!! Was able to figure it out and get it running with very minimal BS in about 5-10 mins.

hello humans I can't compile cpuminer-multi on my arm device
help me

This thread is for cpuminer-opt, not cpuminer-multi. You might have better luck in the cpuminer-multi thread.

The error is in ARM ASM code, possibly a syntax error, but I know nothing about ARM ASM so it's just a guess.

Is there any coin worth cpu mining right now?

That depends on a couple of things (at least):
1. CPU type. Generally, Ryzen cpus will be a better choice for mining these days, especially those with higher core counts and larger L3 cache.
2. Your strategy. You can mine a coin believing it will moon one day in the future. Then you might not mind it not returning more than a few cents a day now. You can let the miner do its work and forget about it until the day the coin moons and then rake in the profits selling.
Or, you can spend a lot of time researching the coin of the day and mine it short term to see if that will earn you a quick buck.
I think XMR has potential to go higher in price and am mining it.

I have a feature/documentation request. I think it would be good to document which algos can take advantage of some of these newer CPU instruction sets. I've been mostly a GPU miner but CPU mining really intrigues me and would like to do it as a side project. I also think documenting which algos are no longer "supported" would be beneficial, or somehow segregating them from the rest. Just looking at the algo list its apparent that most of the included algos will never be seriously mined by a CPU. I definitely appreciate the work though, I have been using cpuminer-opt off and on for years now

The short answer is any algo derivative of x11 or containing parts of x11, otherwise known as sha3 based.
The irony is that the algos that can use AVX512 etc can't compete with GPUs.

The long answer requires searching through the code of each algo.

I'm not sure what you mean by no longer supported. I focus more on newer CPUs and algos that are still mineable
with a CPU (although difficult for some) but all algos are still supported.
