Well drank the kool aid and have 2 new rigs 5 GPU board setups off of Newegg. (One rig is up on Silent Army (Ubuntu) the other is in the mail supposedly.)

PROBABLY COULD HAVE SKIPPED THE 2ND RIG AT THIS POINT! (you think?)

Got 10 Sapphire RX 480 Cards (see link below). Supposedly with bios tweaks and such I was told I can creep these over 50 h/s each.

Anyway thus the poll. Having a bit of buyers regret. (One OK. Two..meh....)

So take the poll and/or post here on what you all think of thie 'kool aid' drinking ZEC coin POW mining endeavor.

(Finally fell into the common trap of being (or realizing) I know am a big miner making on LTC mining 2.2k a month after expenses. errr......slipped up and forgot that is 'real
money we are talking about chump' and drank too much 'kool aid'. On the one hand it is very nice to be in this kinda position and I can mine other stuff to get out of this hole
say in a month or two and move on. But kinda embarassing that I lost track of the fact I stuck 4k probably in all this.)

Dare to Dream,  they say. Go for it, they say. OK on 1 GPU rig maybe. On 2 GPU rigs...er me thinks that was a step to far.

Hell, it is only money. Right.  Chump or Champ on this. We will see I guess.

Take the poll. Post/Vent here on do's and or dont's on this ZEC Coin POW mining bit of 'speculation'

(Damn, should have had the 'intervention' before buying the 2nd GPU rig at least!) :(

Put the rigs on ETH or ETC (some argue ETC is better for selling due to less diff)

I'm assuming you bought some open air rigs for these setups or built them? What did you buy if I may ask?

I'm considering building/buying an open air setup.

Below is what I paid for 5 cards so it will be a 5 card setup. Something like 1800 bucks invested more or less I guess. Not sure yet my buddy is putting it together
at the colohub data center  I keep my Titans (some anyway others at home)

But say it runs 4k for both....The first one..Ok..that was a gimmie....still think I went over board on the 2nd one. Oh well.....use this as a 'stop check' then next time

I want to blow my Titan $$$ mining month to month on something I guess.

They will be open rig. (IF you can call open rig zip tied to racks and hanging that is) :)

no worries eth is doing well  just mine that.

I bought parts for a new rig about the time ZCash went live - but it wasn't specifically built for ZCash.
Unfortunately, I didn't switch rigs over from ETH soon enough to catch the double-digit per BTC (much less the very short triple-digit per BTC) early adopter crazy pricing - but I did get enough switched over soon enough to catch some income when it WAS still over 1BTC, so no remorse at all.

 At this point it looks like ZEC is going to go into the "basket" including coins like ETH ETC and XMR in the "whichever one is more profitable folks will switch to 'till it changes again" group.

 Up side, it's split hashrate around enough to make ALL of the "basket" more profitable via lower difficulties, for a while at least - and will probably help some when ETH goes POS to soak up some of the "nothing to do, gotta find something else" hashrate available at that point.




 And yes, I still have most of my A2 farm mining LTC (and merge-mining stuff like DOGE), though I'm not pulling in 2K+ a month on that.

Hey, at least you didn't buy ZEC

Mining is better as a whole even though ZEC has fallen hard now that it is 1 week old and the rigs have value in themselves, so a true roi shouldn't be too painful.

The real losers of this equation will be the people who knew nothing about Zcash (miners reward spool up) and bought the coin at inflated values, and people who got scammed into buying cloud mining contracts that will NEVER roi.  I advised people multiple times that could mining will lose them a lot of money, but they were still willing to throw thousands of dollars in the garbage.

Well as for me, I didn't buy anything new just keep my current rigs going and I added 2 new cards a week or 2 before hand but I had planned on doing that before I learned about Zcash.

I would not have bought RX480s, they're not really more powerful than the RX470s.

That said, I think ZEC will go back up once they fix their z wallet bug. Also, it's still more profitable to mine than ETH for the moment...

The mining profitability of the ZCash and Ethereum will be similar in the future. That is becasue miners switch between the two.

There are actually quite a few profitable coins right now to mine compared to say last year at this time. Even with some of the hash leaving ZEC, which is a good thing actually, the ETH, ETC, and EXP prices are high enough to still comfortably make money mining. As others have suggested, once enough hash-power moves back to other coins, the profitability of ZEC will stabilize somewhat. Sure the windfall profits are gone, but you can still ROI on a rig in under 6 months, which IMHO is still quite good when compared to equal opportunities outside of the Crypto world.

no, it is not.

Uhm, yes, it is. I have 3 rigs total, 1172W @ wall for 490S/s. That's almost 24$ a day of profit. No way I can achieve this with ETH.

I use something like 20% less power on the same rig for ZEC.

You need to recalculate those numbers for eth then...

I put hash rates for a 5 card rig.

That is assuming you can sell those coins for the same amount after you mine them, price will probably drop by then, so you get less actually.

You must seeing something different or get alot less mining Zec than I do,

I get around 1050/sol's mining ZEC as I have more CPU's available than I do GPU's.

If mining ETH, I have about 420MH dual mining so it breaks down like the below for me.

I guess it depends on what you have available as to which is more profitable right now.


https://s16.postimg.org/vhxzpgmkl/Capture_E.jpg

It seems your rig can do 2.39W/Sol/s. For most rigs, they can only do 3W/S or more. What is your setup?

Oh ok that explains it then, I have no cpu's mining zec.  If you got the cpu's zec is really good then, considering how much hash you can get for them.

"Heavy" undervolt ;)

1st rig: 4x RX470 8Gb Nitro+ core 1100/mem 2000, 1500 timing strap and a -137.5mV offset
2nd rig: 4x RX470 4Gb Nitro+ same configuration (2x Elpidas, 2x Hynix)
3rd rig: 2x R390X, just modded with hawai bios editor. I stopped using them with ETH, but with ZEC and the latest claymore, they give me 55S/s each. Can't recall the exact config I put on though, would need to check their bios.

As for profitability, My 2 RX470 rigs would pull out around 114Mh/s each for 530W @ wall. With 228Mh/s, I would mine about 1.5 Eths a day according to https://www.cryptocompare.com/mining/calculator/eth, even with the current difficulty of ETH which has lowered with everybody mining ZEC.

im thinking about the long run on zec
eth will be pos in the next couple of months
so everyone will fall back onto it.. it will never be 1-2 btc per zec again but it will be the coin to mine

You got to take this in perspective, the only reason it was so high at launch was due to the scarcity, not only the normal scarcity of a new coins coming on line, but compounded by the fact of a slow start with fractions of a ZEC as a block reward for the first many blocks.

Further more, much of this "hype" was probably due the speculative manipulations of traders. Keep in mind just because some insignificant amount of zec, say 0.00001 zec sold at 1,300 BTC, doing the math it comes out to 0.013 btc or roughly $10.00. So compound this over many trades and some well off trader who has access to a lot of early mined zec can spend a couple thousand dollars buying some small trades like this to "set" the market price, then sell into the fomo of others. He/she may have even just bought their own sells for a period of time to establish this fake price point.

So understanding all of this, we can see that the block reward was only 1/10th of what it will eventually be most of this period. Right now it is still around 1/3rd of the eventual 10 zec per block the miners will see (with founders getting the other 2.5).

So ignoring the crazy initial bids of the first day(s), as well as to make the math simple, we had a period when the 1 zec block reward was worth roughly 1 btc.

Now we have ~3 zec block rewards when zec is worth ~0.35 btc, so the full block reward is still roughly worth 1 btc in total.

By the end of the month when the block reward is worth the full 10 zec to  miners, I would expect the price to be somewhere around 0.1 zec/btc, or again roughly 1 btc for the full zec block reward.

I am sure it will bounce around all over and go under that somewhat, but then again miners have already left so the difficulty has gone down slightly and the chances of any given miner to earn zec has also went up slightly as a result. In the end it will usually balance out so miners can make a profit, but no it will not be a instant money making machine.

 Depends on your specific rigs and specific energy costs.

 For *ME* right now ETH is more profitable - but it's close enough that could change tomorrow.


 ETH last announcement I saw was middle of next year for POS - though 2 GB cards will get "DAG size killed" sometime sooner.

Yeah if you wanted to make the 'long bet' at some point below then ....assuming difficulty allows it for ZEC you mine like hell and hold

then when the ETH and ETC go POS coin...all those GPU ETH or ETC miners go to ZEC mining. Either a good thing or a tank at that point


balls to wish ratio on this is large...no clue...just saying

Well we still have ETH so its not a big deal

You need to look at miners reward.

For ETH its ~$300,000 daily.

For ZEC currently its ~$400,000 daily.

So if this price and reward ratio hold, we will be making double the profits pre-ZCASH.

But the price ZEC/BTC definately will keep going down. Not only this month but for the entire year while the supply keeps increasing.

I reckon the ZCash price will be about 10 to 20% of the current price, that is due to the increased supply.

I switched all my AMD GPU's back to ETH today.

After calculating based upon just my GPU's capability, ETH more profitable as of today for me (assuming ZEC value continues to fall)

I left all my non-AMD GPU's and CPU's on Zcash though.

I did the same apart from the R9 280X. They are more profitable to mine the ZCash than the Etherum.

Was such a waste of time modding and flashing all these bios's back and forth. Installing Ubuntu... then Windows ... then Ubuntu again.

Yup that's what I decided on Zcash launch day to use the Nicehash miner and just get paid in BTC since it ran in Windows.

I think zec might be a worthwhile coin to mine after we reach the full block reward.

But the way it is now, you mine your coins and by the time you sell them its worth wayy less.

I had thoughts on getting 2x GTX 1060's or RX 470's with the upped profits knowing I can move them to another script later but I could tell ZEC mining would tank

Even while it was profitable the block rewards were growing far slower than the price drop on the coin and the network dificulty was rising in a frenzy

The big reason the price dropped is the model We could have literally divided the price by 100 and multiplied the block reward by 100 and mining would be the same profit but less hype because everyone bought into the sticker price of a single coin. That combined with pure profitability made ZEC into a perfect pump and dump coin

I'm glad I did my mining with Nicehash and instant sold it while all the Suprnova people were basically losing value between the time of their shares and when they sold it

ZEC may someday get up in market cap and have its place as a top 10 crypto. The way I see it unlike BTC, LTC, and DASH it is not an ASIC coin so the mining is less centralized by mega whale farms. Unlike Monero, ZEC has optional transparency which makes it both viable as a darknet coin and a mainstream coin. Off hand I may be off with the details but isn't Monero and Dash both victim to large premines which arguably can be worse than the ZEC 20% mining tax by the devs? Lastly, it is clearly better with GPU's but it is still pretty good with CPU's which a CPU coin allows more people to just mine it making it even less centralized in hash power

Thing is the total supply of 21 million like BTC makes it in a seat to overtake BTC which is our established gold already. As for general currency, I do not think the public wants to adapt something we have to all count heaps of zero's down from the coin for every and all transactions. A coin where the total supply is much higher with a value per coin within the ranges we're familiar with in current fiat or that of a century ago before inflation is more ideal. Dash and Monero are not winning here either. So I basically see Zcash as the competitor to Dash and Monero while technically being more advanced to BTC but just too late to be gold in crypto

Time will tell. Maybe this will be our mining coin after ETH is POS


I intend to not invest into ZEC until the block reward has finally grown. It's only granted to decrease value as the reward grows and the supply is practically multiplying since it is still new.

Everybody is moving to mine zec classic.

and this is priced at what and where can you sell such?

(just saying so new that only person holding it is the zec classic satoshi who ported it...is that what we are talking about here?) :)

not a slam just find nothing on what you say ..google just shows zec current

If you missed the Zcash train, there is another clone that just came...

[ANN] Zclassic, Zcash Fork No Premine, No 20% Founders Tax

The ZClassic is just a copy cat. It is worse than the ZCash if it does not have proper development.

I don't understand why people would buy new equipment for a new coin when they already have suitable equipment.
It's not like buying a new dress for a big night out. Then again I don't like Kool-Aid either.

Don't think so. No development at all. What they did is just remove 20% developer free from zcash and thought that everyone will just jump over to new coin. Well nah. Some (i hope everyone) people are looking at coin's future before they start with mining or invest in it

A few days before the launch of Z-Cash I said this coin would go down as one of the most over hyped mine and dump coins this half of the year.

Seems more and more every day I am correct. Glad I put money into Stratis instead of Zcash  :o :o

As far as the OP, I didnt build rigs for zcash. I did, however, build a little farm for Ether (a bit later into the hype than I should have but so be it). I mined Ether for awhile and then switched to zcash on day 1 and have been mostly there ever since. I do keep up with price and such and will switch back once the profitability dies. SOme pictures and specs here: http://forum.feathercoin.com/topic/8678/new-farm-setup/

If you build a rig for Ethereum, then it will be useless for Ethereum within a year as it will be PoS by that time.

the hashrate and money will likely move to somethign else, like etheruem classic or zclassic or whatever any new thign will come out

the profit in those coins can not simply disappear it will re-arrange itself to a new beginning

i still remember when many were saying some months ago that after ethereum the mining scene would have been dead, look now you have other good options...

You worry too much. GPU mining didn't die off with Zcash. You just have to adapt.
It may not be as profitable as you first thought, but you'll get your ROI and profit too, just you need more patience.

Find another coin.
It's clear that the hype blinded you. How could you have thought that a coin so easy to mine will worth that much for long?
But, as somebody else said: at least you didn't buy Zcash :D . Your loss is not a loss, just an investment that can be recovered.

Well my bet is still the 'zcash' has 'legs' so to speak ..it will dump down to a level of say ETH and LTC eventually when there are enough coins (or below)

if at that point you decide to still mine it and hold that is your bet...if you decide to mine ETH or another coin that also is your bet

right now I'm shocked that at the slow start at 1/2 the block reward it is still around 95 bucks and has kinda gone sideways the last 3 days or so

so still kinda wondering where the bottom is on this coin

The main 'hope' I guess is if/when ETH goes POS coin..folk will come to this coin after the fact if not before

(still better then an asic at least I will have stuff I can sell and make a couple rigs out of it for my home use)...supposedly no 'doorstop' issues like asic equipment

but yeah...one rig would have been OK I guess in hindsight to play with and toy around with...er 2 rigs probably (er really) was overkill I guess

GPU mining is all good.  Even if diff of the coin goes up 2x, and btc price goes down 2x, you are still making profit.  (considering a good electricity rate).  Plus you have the used value of the hardware.  Calculate 3-4 months, maybe up to 6 if you are really unlucky and the rigs are paid off. 

Bingo.

Two of the rigs I have were built originally to mine LTC back in 2013 or so? They ROI'd and then were switched to Feathercoin and then to a multipool for awhile. At some point GPU mining dried up and I turned them off for about a year. I eventually powered them back up mining feathercoin again and then Ether and now Zcash.

Its not as simple as mining BTC on an ASIC, set it and forget it, but if you dedicate time and effort into it then GPU mining can be profitable from time to time. Not everyone has the time to invest though.

I think the cards you bought in 2013, such as the AMD 7950 or 7970 are still making you money on the ZCash.
