I’m really surprised people still trust Innosilicon with their track record of underperforming miners and slow delivery among many other things. I get we all want cheap miners and competition, but they’ve already been known to deliver less than acceptable products.

Bittawm is actually selling D3s for $2500 each right now with shipping included (reputable member in the computer hardware goods section). Just be warned these things (as do pretty much all miners these days) sound about as loud or louder than vacuum cleaners and you can really hear em. Spending a hundred bucks or so can get you some decent soundproofing, Philipma has a YouTube channel where he documents making some Avalon miners quieter. They went down to 60-63db or so iirc but still a little bit loud.

Mining on laptops is a horrible idea because they’re not designed to be run at full stress 24/7 and most laptops have very bad cooling systems. The 940MX has terrible mining performance and cpu mining with anything other than XMR will usually result in tiny profits. Don’t mine with a laptop, build a desktop style rig to do that.

It’s just not happened to a large extent outside of some hosting centers and farms to my knowledge though. NA is still pretty far behind in mining. I do hope we get more large miners to remove bitmain’s iron fist over BTC though. I recall there used to be a decent sized farm in Labrador but it was liquidated or something like that.

I don’t know about you, but I wouldn’t trust reviews from completely new accounts that have one post and one post that is promoting a shady site. Don’t fall for the scams. Just buy from the manufacturer or from reputable forum members with escrow/ebay if you’re feeling brave.

China and other areas with exceptionally cheap electrical costs will probably continue to dominate in mining as we’re already feeling the impacts of slower node improvements and less efficiency jumps. It’ll soon be down to who has the absolute cheapest electrical costs soon; at the rate price and difficult is increasing right now the end of home mining is approaching even more quickly than most of us expected.

There’s not much reason for an upgrade as it stands right now though. RX 400/500 series cards are still largely profitable, same goes for the 1060/1070s. Unless you’re truly running some older 300 series cards or 200s or just trying to snatch some X11/Scrypt ASICs, there really isn’t a reason to do so.

My guess is Bitmain will continue accepting only BCH until S2X forks. Don’t know what they’ll do then, possibly only accept S2X coins or BTC again. Either way Bitmain is keeping BCH on life support by doing this, probably so BCH is still profitable while EDA is up when they are mining BCH.

In addition the application of the thermal epoxy might be different or whatever thermal compound they put on their chips nowadays. Temps look okay the way they are so I wouldn’t worry too much about them. I remember having to repaste miners in the past and using up a whole tube of good quality paste because the paste on older Bitmain miners weren’t applied very well.

Below 90 is a good goal to reach for you. Under 70/80 is actually preferred, you might want to consider switching your mining area or adding more airflow to the miners.

A lot of people bought in back when ETH mining was much more profitable and are now having buyer’s regret, so they’re selling their rigs (or electrical costs made it not so profitable anymore). Mining isn’t dead but right back to about where it was before the big mining craze.

The only cloud mining provider I trust is hashnest, and most others are just pyramid schemes that are barely alive. It’s infinitely better to have access to your miners through hosting or mining in your own facility/home rather than investing money into an unknown platform. People need to stay vigilant because these scams are common and will continue to be common.

Yes, especially with the bitcoin cash EDA that is happening now as miners switch to it temporarily for greater profits. It’s uncommon but possible, most of the time these dips are very small and afterwards difficulty will usually continue to spike even quicker.

The Antminer S9 is already terrible and breaks easily “new”, I would not risk buying em used as you don’t know what sort of issues could pop up on it. Used Avalon units might be a better option. Buying hardware from reputable forum members is usually better than buying from some other sources, you have an accurate idea of how a miner works, issues, etc.

What’s your electrical cost, location, are you ok with a machine that is a loud as a vacuum cleaner running 24/7, etc? The question you asked is very ambiguous and you can find the answers in here by reading a post or two. This question is posted almost daily.

Don't. Laptops have bad cooling systems and they can easily overheat resulting in irreversible damage. Most laptops also don't hash very quickly and most of the time it's not worth mining on them. Keep your laptop for normal use and not for mining, for mining use desktops or open air rigs. Even with free electricity profitability will be marginal at best. If you are trying to educate yourself about mining doing it for a short time is ok, but even with free electricity do not mine on a laptop.

Yes, but I'd suggest not mining it as a small price change could make your mining less profitable than, say, XMR, ETH or ZEC. To be absolutely honest, for maximum profit and ease of mind choose one coin and stick to it unless there's a major profitability shift. Profitability may be slightly higher on one chain compared to another but that is usually temporary.

Photobucket doesn't work anymore these days (they want you to pay extra money for third party viewing), you need a new image hoster. Imgur works well if you're not trying to embed it in a post.

The point of faucets is to get website owners money through advertising. It's not worth the work of clicking captchas for a tiny reward, I wouldn't even use em if you want some coins to play with (testnet is there for that reason). It's the ultimate waste of time, except you get paid a few hundredths of a cent per site for your effort.

ROI is coming much slower on these units now, not sure if it's even worth buying now myself. OC will probably lower efficiency so I'm not sure if that's good or not, and profitability will continue down if Dash price stays as it is and difficulty keeps creeping up.

Where are you guys getting your difficulty information now that bitcoinwisdom is still displaying faulty info?

Seems like Bitmain is just going to continue to crank out more and more miners as difficulty goes up. Perhaps the end of home mining is approaching faster than we expected... I have never seen numbers like this on any difficulty period in my time with BTC. Let's hope this doesn't last.
