This.

Peercoin was occasionally above the profitability of BTC, and the day the halving came, difficulty exploded. The profitability of PPC is still above BTC, but the difficulty is actually starting to go down. Note that almost everybody with old miners have begun to do this or leave altogether, which is why the hashrate's going down. Not everybody is completely shutting down, hashrate has simply moved elsewhere.

There's just so many issues with this that are so obvious.

1. Doesn't belong in this section, pretty misleading and it's clear this is a ponzi. Not sure why people put their little cloud mining websites in the services section.

2. Almost the same design I see every single time I see one of these websites. Watch these guys run in about 3 days after somebody deposits 100$.

3. Caveat emptor. Cloud mining isn't nearly as reliable as having a physical machine; you've got less risk HODLing and hoping the price will rise than investing in one of these sites.

I won't feel any pity for someone who deposits their life savings into this, you've been warned plenty by everybody here, including the people in the gambling section where this should probably be. Not even sure why this is still here, this may as well be in Investor-based Games with all the risk there is here.


There we go, moved to investor based games. You've got enough attention from services, wrong place, wrong time. Don't mess with the forum.

'Free' electricity is not always going to be as 'free' as you'd like it to be, there may be limitations to how much you can use. As for a miner, try getting cheap S7s or S7-LNs. S3's are also good for cheap hashpower, but the S7-LN and S7 is currently the best bang for the buck.

Most PSU'S will work for BTC mining, but make sure you get are good psu from a reputable brand, not one from some company called 'cheappsu' or something offering 1000w at 50% efficiency. EVGA offers good PSUs, and almost anything you can get your hands on at Amazon and Newegg. Always check reviews for PSUs; your mileage may vary with each psu.

The S5 is pretty inefficient and not nearly as good as the S9 with even free electricity. Common complaints with the miner include loud fans, and plasticky casing unlike the sturdy and well-built S3 workhorse. They do run well with a replacement fan or two, and they still run pretty well, considering their age. With free or nearly free electricity, you should make a few dollars a day for quite a long while. Fans aren't a big thing if you place them in a very isolated place, but I guarantee you won't sleep at night with an S5 in your bedroom.

Oh, and one more thing- I saw a thread once where a S5 casing was partially melted. Not sure where I saw it, but it was pretty shocking. The casing is plastic, but it still does work.

The best miners atm for most people are the S9 and the variants of S7. Avalon 6's are still viable for people with low electricity costs, but they aren't nearly as good as S7s imo.

Dragon made some old miners, to give you an idea, a large desktop sized miner running with coincrafts at 1 TH/s at 1kW. They also made some stick miners running Zeus chips, Scrypt. I have a few and they run well, you can still buy them off eBay and Aliexpress, but their efficiency sucks.

Gridseed made some Scrypt miners, their orbs were pretty efficient, but the blades not so much. They were expected to make a dual SHA256 and Scrypt blade-style miner, but it never came out.

Rockminer made a small orb-sized SHA256 miner, as well as the more well-known rocket box and the r-boxes.

Zeus made some Scrypt miners that ran pretty well, until the newest generation miners came out.

The SMART miner was probably a scam. There were never any reviews at all for that product, and so I'd be inclined to think I was a scam. It's possible it's legit, but the chances are slim to none.

Yes miner was a pretty clear scam from the beginning; somehow some people bought it and were/are requesting refunds. The last time I checked the yes miner thread was about 2-3 months ago, so I'm not quite sure.

I'll say what I'm going to say right here: Mining is like gambling since there are so many factors that can lead to negative roi or doubling your money. You have nearly no control over the price of BTC nor the difficulty. What I said usually does not apply for people with very cheap electricity, although there are circumstances where it also applies. Everyone has different opinions, but really, if a miner was priced too high by a manufacturer, nobody will get roi above, say, 5 cents. This makes mining impossible for most.  If difficulty goes up 10% more than expected, a miner will be thrown off the expected track quite a bit. What if price falls? What if? There are so many variables in mining that you have to accept this is a very risky proposition, and you might as well be gambling with around 70-30 odds for most people.

Remember what I said about electricity? Cheap electricity almost always means ROI, but it also depends on cooling costs. A tropical region with 3 cent electricity will often incur more electrical costs than a cool region with 5 cent electricity, as more electricity will be needed for cooling. Mining is an uncertainty most of the time for people with above 5-cent electrical costs.

Some, but barely. I mined at a loss until this halving, and I plan to keep pushing it. I turned off 2 S3's and replaced them with an S7-LN (replaced psu, as it broke pretty fast). The network seems to have turned some off, with a dip a day or two ago, but I don't see as much of a drop as I anticipated. Perhaps more network hashpower is in S9's, or most S7 users have really cheap electricity, nobody knows. I see difficulty dropping or staying stable in the close future.

Something interesting I noticed in PPC was that difficulty exploded as I expected it to, as people realised that the profitability was almost the same as the pre-halving BTC profitability. It's still slightly above the profitability of BTC, but I don't think all of the hashpower 'turned off' has completely turned off.

I'm assuming they're going to release the S9 after the S7 becomes unavailable to keep people in Hashnest, but it's already a bit late to invest in them. Most of the people on hashnest have left, as they earned a bit of money trading between the different hashpower, and when it boiled down to the S7, they just sold or redeemed and left. I don't see many people in the chat these days, and the hype for hashnest has gone down a bit. The S7's still chugging along, though, so it may be a while before they release the S9 on there. I even speculate that Hashnest will eventually just shut down because of disinterest eventually.

an X means a failed ASIC. It simply means an ASIC will not be functioning properly, and you will get slightly less hashrate. Not much to worry about, as long as there's no more than two it's still a good miner. Ask him what happened to the miner, because depending on the issue, you may have to change fans or something similar to prevent more failed ASICs. I'm assuming he let the miner overheat, and the ASICs failed as a result.

Sorry, I didn't check the spreadsheet yet. I thought the 1 was somebody else. Thanks for letting me know!

So.. am I in? I've done everything you've requested.

Everything depends on cooling, power costs, backup, and area available. Your area should be neat, as to make cooling as effective as possible. You'll want cheap electricity in a cooler place, so you won't use as much power on cooling, but still need especially cheap electricity. Cool and cheap is a huge factor, which is why many farms are located in Washington state in the US. You'll want extended backup to keep things going in case of power going out; it takes time to shut miners down safely. There's many more factors like cost of miners and what model, but assuming it's an S9 farm with 5-cent electricity or less, in an ideal enviroment, it should work.

Reapplying, like you said. I'm currently on my phone, working out the errors on my copy-paste. Signature should be good.

Edit: all good! I hope this'll be a long-running campaign; it probably will be with you as manager.

Thanks, GP! I would like to notify you that I am leaving this campaign. 1 spot open now.

LN'S are already almost as cheap as they can get. The resell price of the machines is relatively high, especially when bundled with a PSU. No reason not to buy one, the S9 is a bit harder to sell and currently overpriced(imo). Solo is definitely a bad choice with only a few miners, and you'll need a lot of troubleshooting and things like that. With the price of miners like an S5 around 130 on eBay(again, assuming you're reselling right now instead of the future), you could easily get 300 out of an LN. They're probably the most cost-effective miners for people with cheap electricity right now, but really, it all depends on how much you pay per kw. 

If it's still open, I'll change my signature and avatar once accepted:

I know you said around 15, but I have pretty good post quality, so I think I'm a contender for this campaign. The post count though...
I see ads are already up for the campaign, one right above my post.

Try looking in the altcoin market, there's plenty of campaigns offering their participants altcoins for posting. Offering signature space is usually reserved for the most trusted members on this forum with green trust and staff status and whatnot, and you've got almost zero chance of getting an offer. I suggest you look around a bit and try finding a new campaign to join; just because one didn't accept you doesn't mean they'll all reject you. Try improving your post quality, and reapply. PM the campaign manager and ask them why you were kicked so you can improve in the future. Nobody kicks for no reason.

Real? If you're looking for a real writer, you might want to find some professional services. If it's been this long and you still haven't found anybody, congrats, it's time to move on. "Good" is simply an opinion, and there are plenty of people that hire content writers off here, and I don't see many of them being horrible. Spamming has been gone for a while ever since the campaign managers all started doing something. Saying that the whole forum sucks and can't do what you want is what I see every single day on this forum. There's plenty of reputable people here that do good work, and if you don't like their work, don't go shitting on them. There's plenty of flow these days in this forum, and there's always new talent every single day. Just because the people you've hired in the past have left doesn't mean the whole forum is devoid of skilled workers.

Interested, shipping costs to 29466?

You don't need great internet to mine. You can mine on dial-up if you want, mining isn't very related to latency, and even with the slowest internet, the worst you'll get is discarded shares. S7-LNs work great for cheap electricity, if you're truly new, as they provide reliable hashrate at a good efficiency. The S9 is probably going to be your best bet for profit, but if you are actually new, I highly suggest you get the S7-LN to see how things work here. Otherwise, good luck!
