That's neat. You totally pwned me with your proud math skilzz... all the while forgetting that at no point did I say I'm currently mining this coin nor did I say I couldn't figure out profit estimations.

The double and triple instance trick has been kicking around the ccminer thread for the last year.

Have a nice day eth-baby.

line 2233 of main.cpp:
 static const int64 nTargetSpacing = 10 * 60; // 10 minute blocks

* 1440 minutes in a day, divided by 10:
* 144 blocks a day (diff retargets every 6 blocks, so lets say 147 blocks/day just for arguments sake, perfect timing like an optical distributor).
* one block has 40 coins, times 0.00192500btc per coin making each block worth 0.077btc/block.
* 0.077btc per block times 147 blocks a day - means the chain is worth 11.319btc/day for mining alone.

we dont even need to know the proper bitcoin/scrypt derivative (2^32 vs 2^48 vs ..) difficulty algorithm. why?

* average hashrate of 2800mh on suprnova's xzc pool
* world hashrate of 7000mh on suprnova's xzc pool
* we assume approximately 40% of the blocks will be found by suprnova (more if ocminer uses candy).

so 11.319btc/day times 0.40 equals 4.52btc/day via suprnova.

* since we know that suprnova has 2800mh, we can slot out figure in there (lets say that your uncle was ec2 and you managed 20mh).
* = (20 / 2800) * 4.52btc/day = 0.03228571btc a day mined all day

yes, its not 100% accurate.
blocks are found early/late, orphaned.
certain types of pools dont let others know when theyve found blocks, in a timely fashion.

the best part? this is probably grade 5/6 arithmetic.
dont forget your lunchbox.

(regarding ragging on djm34's miner, feel free to drag your memory clock all the way down to 150mhz and take note of the results, hint on GPU: run more threads than you would normally... x2 or x3)

It shouldn't take you long there joblo. The code is very similar to the lyra2 code

I know someone who has been unusually quiet in these forums lately who could have made a play with
private Cuda miners.  But I agree AWS users were the big winners.

I'm just speculating because I don't know how much lyra2 is left in Cuda after Nanashi doubled the
performance. I think the nature of the algo is the biggest impediment to GPU performance.

I've really enjoyed some of the new CPU algo development recently with multiple devs contributing to
optimize in the open. It seems to have motivated some others to give it a try. It's nice to see continued
interest in CPU mining.

My contribution is coming soon, maybe a little late but still significant.

Thanks for yours.

You're both wrong. I was 'opposing' both of you. Mining has relatively little to do with price with the exception of small coins whose emission completely dumps the exchanges every day.

You're discussing miner problems as if they're investor or exchange issues. They aren't. We can mine something into the ground and it can be extremely negative from a mining profitability standpoint and the economy of the coin can function perfectly fine. They're completely independent. Investors give shit all on whether or not things are profitable for you. Things tend to auto-balance based on users simply being able to figure out a profit calculator and moving hash off a coin, that's the only relationship there is with the market. The exchange movement has nothing to do with the miners though.


Making a grossly underperforming miner for the sake of selling a better one is a little shady. I admit, it's very stable and it uses almost no electricity... ...but that also means someone else is probably making 2-3x as much as me with the same hardware. I have no doubt you have a better miner.

Hopefully this will catch the attention of bigger devs which can make a fee miner like EWBF, Nicehash, or Claymore.


Everything aside, this coin has acquired too much 'hype' for the relaunch and people can't figure out profitability because Whattomine hasn't made a calculator so they're all mining blind and assuming it'll pan out.

Don`t forget AWS could and prolly is rapping still 80% of zcoin network!

There are many way to obtain AWS, etc, botnets, etc not all are legal, but its the world we live in

one AWS instance can do +2Mhs so do your math, and not all pay for it (legal or not)!

can the ccminer be optimized more for sure, can it be 5x hell no, so there is no chance anyone has 10Mh+ GTC1070 miner
AMD is slow at lyra2_xxx always was, can it push 100% more, sure it can, but can it push 1000% more hell no
and AMD freaks you have bunch of coins with lyra_xxx and you should know AMD is bad for it!!

Now why would the devs have a private optimized miner for the coin when we know they get a portion of everycoin mined plus a portion of whatever is sold on exchanges. If you want an optimized miner real badly talk to wolf0 he's selling an AMD optimized sgminer kernel for 0.25 btc a piece 

what so bad about making profit ? Aren't you there for that ? Isn't the reason you are trolling here, because you think you are entitled to more profit yourself (without giving back anything to anyone) ?
Please stop that hypocrisy.

and for info these were offered to you by the Zcoin team... and nothing force the dev team to do this (many coins are released without miners...)

Welcome to the wonderful world of shitcoin development. You think developers do this for free? Of course there are private optimized miners.

If you think miners of a POW coin does not determine value, then crypto might not be for you.

According to my calculations (and they are pretty much reliable I think) right at the moment mining with CPU gives about 4 times less than before the change (exactly the same setup gives 4x less coins).
So it is utterly unprofitable, unless the computing power is free.

I am a long term miner of this coin, so I won't shutdown the machines right now... Except obvious reasons like GPU joining, I suppose there might be an effect of slow diff retargeting and/or the fact there are too many GPU miners who got excited and jumped on this coin during the algo change.

But if this stays the same for few days, CPU mining for this coin could be officially closed for everyone except botnets, as even with 80% VPS discounts this would be unprofitable.

it worked!!!

Almost. The diff follows the nethash. Price follows simple supply and demand. If diff doesn't work right it
affects supply and indirectly affects price.

It's only when you calculate mining profitability that price has an effect, and only applies if you exchange
to your currency of comparison.

About last night...

It backfired, plain and simple. So may things went wrong.  People are complaining to DJM34 about the poor
AMD performance. He was not hired to rewrite lyra2 from scratch or optimize it, just implement zcoin. It wasn't his
fault he started from an ancient base with poor performance on exiting lyra2 algos, The zcoin devs should have
known that AMD wasn't going to be competitive because it wasn't competive before.

For Nvidia the core lyra2 code was already very much optimized, but the perforance on zcoin is still poor.
The algo parameters are just not suitable for GPU mining, even with optimized code.

So you have an algo that already has limited gain potential for GPUs over CPUs due to its I/O requirements and
you increase those requirements to further reduce that potential because you want to encourage GPU mining.
It doen't make sense.

Everyone knew the cutover was going to be like a launch and knew when it would happen. Everyone with AWS
credits knew just what to do with them and when. It gave them a golden opportunity to use their credits at the
most profitable time.

Everything that happened was completely opposite to the desired intent.

and the earth is flat... yes we know
(at last a conspiracy theory   wait here while I grab popcorn, popcorn feels so much better than deception  )

Horrible! Developers artificially increased the complexity of the production coin! And, like hamsters, We ate this deception! Developers somewhere running a private pool with an optimized algorithm and they get a huge portion of the coin! Compare the total hash of the network and the fact that the hash in all pools!

wat ?

im guessing djm34 has been around the world,
you know.. globally

Not sure whom you are opposing to, Amph or me...

Anyway, while I see your point, one cannot deny miners affect the price, while surely they do not determine that. I have been observing that many times, though you are correct I was looking mostly on smaller coins. Its better to tell - miners strongly affect the price, with the exception of the most solid coins, where the demand is big enough to make miners dump unnoticeable.

I have looked at you other posts in other threads though, and can see you are often providing really great insight.

Yes, unfortunately this is probably the thing I was missing. If most miners are like that, then they indeed are only good at securing the blockchain, nothing more.

my Rx 480 gpu giving 200kh/s , and my cpu is giving 250kh/s ..

it's the other way around, the price don't follow the diff, it's the opposite the diff follow the price
