Forgot to sell my BTG at .05 like I planned to, had to stick with .02. I’m personally still sticking with Bitcoin all the way and I’ll take any repercussions that come as a result of it. There’ll definitely be more attacks that will be bigger on Bitcoin as a whole, but as long as the community stays resilient they won’t do any damage. More BTC for me anyhow.

Pictures, please? May be interested but I’d like to see what the laptop looks like before buying. Screen is 60hz IPS correct? Or is it a TN panel?

6.5 cents residential in NW PA. I live close to Erie which has very low commercial and industrial electrical costs, surprised there's not more miners where I live. Nice and cold on the lake during winter, not too hot in the summer.

Electrical fees can amount to be a lot, especially with bs like delivery costs etc. Do some research and see what's pumping up the costs. Some providers are also cheaper than others.

That's unfortunate, guess it's a lesson learned for next time. Hope you still have more crypto to hold for next time. And don't forget not to invest too much into mining, it's not always a guaranteed return.

At least the PSUs can be saved for future use, they're pretty nice for use in GPU rigs and pretty much any ASIC rig.

They definitely aren't a better value than Polaris/Pascal in most cases. They might, not sure about most algorithms, but most people I know are currently mining XMR with them and are doing pretty well. Biggest issue I have for them was that they were sold much above MSRP, prices are going down again making these possibly a decent buy.

I wouldn't have ever paid that much for any miner. Rule of thumb for me is never buy from price-scalped 3rd party sellers or pay more than Bitmain's price or whoever's selling the miner. Unless Bitmain actually sold these for that much at one point from their store.

Bitmain has gone very far downhill and there's no easy way to get replacement boards, especially for the S9. You might be able to find them on the forums, possibly from Aliexpress/Alibaba or eBay/other third party sellers. They are indeed plagued by issues like quality and customer service, I would recommend considering a Canaan A7 over the Antminers. Even though they're cheaper it's not worth the risk of hardware problems and costly repairs imho.

Any information on that? Haven't personally heard of anything new from Avalon recently. Efficiency,etc? Will it at least beat out the current S9s in efficiency, and hashrate if possible?

I guess Bitmain just doesn't want to manufacture more of those form factor miners and wants to stick with only one form factor (S7/9 style). Considering they haven't released anything like the S2/4 in a few years I wouldn't get your hopes up, they're already pocketing enough money with the S9. Not really much need for an "S10".

Wonder if anyone has actually bought any of these. Considering the entire miner is pretty much fully custom it'd be hard to resell its parts and it's cheaper to just build it yourself. Besides that you will also need to pay for shipping from China and customs, and Bitmain also has a horrible record as of now.

Underclocking and undervolting together with memory timing changes results in lower power consumption and similar hashrates. Underclocking by itself isn't as effective by itself. Many people have guides about undervolting and underclocking on this part of the forums for reference and you can also tinker around with your GPUs to find their sweet spots. It can vary even by card brand.

The new Whatsminer and D3s/L3s could be good miners. The Whatsminer isn't incredibly efficient as it is built on the 28nm process but does ~12TH at 2000w, and the D3s and L3s as most people know are nice miners even with ten cents electrical costs. The D3 can be found for sub-$1000 in the US nowadays, and the Whatsminer can be ordered for $1200-1300 IIRC with the PSU. Not sure what L3 prices are like now since I haven't checked in on them in a while.

I've posted this ten times and I'll post it again for all of you people.

The D3 is an ASIC-based miner. It can only hash one algorithm that it was physically designed to hash because of the way ASICs work. The Baikal miners and multi algo X-series miners were FPGA miners that could be reconfigured to hash different algorithms with a firmware update (FPGAs are designed to be modified). No firmware update can add more algorithms to the D3. Only a new miner release could do that, and it'd require Bitmain to make an FPGA-based miner which would also decrease the efficiency of the miner.

Signing this will not do anything and it wouldn't even if Bitmain wanted to. There's no way to "add" algorithms on to existing miners.

The only reasonable answer I would have for anyone buying a USB miner would be as a trinket. There’s little to learn about BTC mining these days as everything is plug and play and maybe a little knowledge of GUI information.

The whatsminer comes with a PSU for cheaper than the S9 iirc but it is less efficient as you just said. Depending on your electrical cost the choice is a little more difficult, but in general I’d go for the S9. Just keep in mind Bitmain’s support has been going steadily downhill and has maybe been slipping even faster in the recent months.

But considering the improvements to the 28nm process that’s very reasonable. Probably was made this way to be somewhat competitive to the S9 and other 14nm miners today. I wouldn’t be surprised if these guys actually beat bitmain at their own efficiency game at this point. Didn’t think there was still more to be squeezed out of 28nm.


Awesome video as always, Phil. Seems odd they would send you a EU plug even though your address was American... maybe they only had EU plugs on the PSUs?

Most miners of this particular generation are going to have an extremely slow break even with small difficulty increases factored in and an electrical price of $.10/kWh. I’d suggest possibly waiting for another generation of miners to come out at ten cents per kilowatt at this point. Even at $.065/kWh (my cost) I’ve held off on buying miners and I’ve actually sold off most of mine due to the huge difficulty jumps we’ve been having recently. Considering whatsminer managed to bring about a very reasonable improvement to efficiency on 28nm there’s likely still room for improvement on the 16/14nm process.

Electrical wiring in your home can be a big issue for home mining and that in itself is a big investment if you can’t do it by yourself. I have a buddy who’s an electrician who did the circuitry in my house for pretty cheap, but I know nowadays it can get very expensive.

4% per difficulty period nowadays isn’t too realistic, increases can get to 10+ and even more with more and more miners being pumped out every day.

Considering most people supporting 2X and Cash absolutely hate Core and the main chain I guess this is their way of trying to damage us. Subtle was probably not part of their plan.


Finally called a correction in time, two days before it happened (or one?). We've been in line for one ever since price started pumping up to $7000.

It could be Hashflare is running into issues, it could also be that they are trying to get their money out while still looking semi-legitimate. No matter how legit a cloud mining company looks, never trust 100% of what they tell you. In fact don't trust them at all. It's essentially gambling. Don't ever invest more than you can afford to lose into anything.

S2X guys dumped BTC and they just moved their money to other coins like Dash, probably causing the recent price rise.

There's still more and more miners being turned on so profitability won't instantly go right back up. It's not looking good for the D3 especially with many more competitors ahead but enjoy this while it lasts. Difficulty will likely continue to go up as it has on the Dash chain.

I used h2c a long time ago and I also left it very quickly after getting a taste of what it was like. They didn't convert your alts to coins instantly and most of the time what'd happen was profitability was good but the price of the mined coins dropped right after your coins were released. I'd say stick to a Litecoin mining pool for now and try not to mine on these switching pools too much.
