I used coinomi to claim my BTG and I barely even trust that. BTG’s coming down in price hard almost to the point where it’s not worth claiming anyways, but never trust an online wallet with no reputation like that. Never even use an online wallet unless it’s for a small hot wallet.

It’s about as dangerous as having a computer on in your room 24/7. Whether it’s dangerous is mostly your own opinion, most reports of radiation from computers are inconclusive and imo the most you’ll be getting is noise and more heat in a room. If it does catch fire you could die from smoke inhalation, though.
edit: typos

Tracking sent. Thanks again
Marvelous. Legit guy right here, will update when it arrives! 👍 Edit - arrived today, totally legit, shrinkwrapped, no tampering A++++ man, thanks!  Cheers!  Something doesn't sit right buying a hardware wallet from a random person on the internet.  I mean, when you’re buying these from eBay or Amazon you’re still taking the risk of getting a tampered unit. Hell maybe your shipment could’ve been intercepted and tampered with mid shipping. Guessing OP just bought in bulk for a discount and is selling these individually for a profit. Just PMed you, OP. I’ll make a new post when I receive my unit. |

Thanks for the pictures, loving the controller board and heatsinks along with the simple design of the miners! Not sure how true Fanatic26's statement about the heatsinks are but at least the design is neat. They still have time to improve on the current design, part of the reviewing process after all if the heat issue arises. Seems like stability on the miners are great too, shame Bitmain doesn't do half as good of a job on their miners nowadays. |

Only problem is that AliExpress generally doesn't accept Bitcoin upfront and the sellers will probably scam you and refuse escrow if you try to get them to accept Bitcoin. $200 for an S5 is a horrible deal, dunno why you even posted this. AliExpress doesn't even accept Bitcoin as an official payment method. Posting this on a Bitcoin forum for a product that doesn't even accept Bitcoin as payment and is massively overpriced =  |

Selling local’s the best way to go, can’t really go wrong. There are ways to make the Antminer quieter that don’t cost a lot (Philipma’s YouTube channel documents this with an Avalon miner, should work with an Antminer too), but it will still be a little loud. Either way, good luck with the sale. Even if there’s not much interest you’ll probably find a buyer since many people don’t want to deal with the hassles of import fees in the EU.

You can buy a server grade PSU and a breakout board plus cables for an easy power up of the miner, and they usually don’t cost a whole lot and are usually 80+gold/platinum certified. The APW3/APW5s resell for a good amount and they can be used for future projects at all. More than likely Bitmain probably sold more than they actually had or shipping delays.

I would like to get one of these beasts.
Excellent performance with some algos.
That is why they are gone from shelves.
Pretty funny how these cards were overhyped with seemingly amazing ETH performance, underperformed, then we all found out about how great the Vega cards are with CryptoNight and they start selling out again. Seems Vega does well in the mining department after all. The cards were also discounted near or below MSRP on Newegg lately so I’m not surprised they sold out. |

Most places let you return GPUs for free within 30 days or however the return time is (at least in the US), and you can google what memory certain cards are using most of the time. It's pretty difficult to get burned that way. The brand name of memory can be found with software or physical inspection most of the time.

Ambient temps don't seem incredibly bad, you likely just don't have good airflow in the room. Try getting a box fan or any sort of fan and getting air in and out of where you are mining. I'd try underclocking to reduce power usage. Sounds like the chips at the back of the miner are getting absolutely burned right now.

I don't think it's as bad as most people make it out to be. The D3 isn't completely useless but what is happening is the X11 algo is in an arms race right now and hardware can very quickly become outdated. Profit is possible, yes, but it's dangerous territory right now and more risky than I personally would like. I just die a little inside every time people mention the D3 needing a firmware update to 'add' algorithms. Sort of sad people don't know what they're buying.

It should be enough to power your card but make sure you aren't using some cheap molex connector. They can handle the power but don't cheap out on it. A dual molex to 6 pin connector should be the safest option.

The S9s aren't exactly the most reliable miners in the world but at that electrical cost it can be pretty profitable to mine. I'd consider looking at the Avalon A7 series of miners for slightly less efficiency but better quality. As with all miners make sure your wiring is up to speed and you have sufficient cooling. Miners can make an unexpectedly high amount of heat.

considering Whatsminer made some pretty significant improvements on the 28nm node process there's still more performance that can be milked out of 16/14nm. It's just a matter of when Bitmain releases a new chip and how efficient it will be. Bitmain's got very few competitors that can touch it in terms of performance in the SHA256 department right now.

Resale value is the biggest one for me. Antminers can't really be salvaged easily and lose most of their value after mining is no longer profitable with them 99% of the time, but with mining rigs graphics cards generally don't lose as much value and nearly all the parts of a mining rig can be sold for a nice amount. ASICs usually need less maintenance, but with a few rigs maintenance isn't a whole lot anyways.

You won't be able to build a rig with a lot more than one or two GPUs if you have to buy all components! For example: Motherboard: 80$ (ASRock H81 Pro BTC R2.0) CPU: 70$ (Intel Celeron G1840) RAM: 60$ (Corsair Vengeance 8GB ) SSD: 60$ PSU: 160$ Risers: 50$ (Frame: ~50$ if you build it yourself) _________________________ 530$ With the remaining 370$ you can buy gpus like (2 x gtx 1060) or (1 x gtx 1070)! have fun building  How much you can earn with GTX 1070 ti? maximum daily? How about building with gtx 1050ti 4 pieces? do you think it can be more profitable? than 2xgtx1060/ 1 gtx 1070? I'm not sure about the 1070ti as the card is new and I haven't really seen any info about them here, but the best bang for your buck is going to be the 1060s and 1070s. If you're looking for an estimation of how much you can make, NiceHash's calculator is pretty accurate and shows real-time estimates of mining profitability. It's not really worth buying the 1050tis imo, better to stick to two 1060s. https://www.nicehash.com/profitability-calculator |

I'm also pretty sure overclocking Antminers with an active warranty voids it. Shipping costs and return costs for Bitmain are already expensive on their own, and it's really not worth overclocking an S9 when it's already good enough. You'll just end up with a brick that's barely salvageable.

You can't mine Bitcoin effectively with CPUs. In addition, the vast majority of altcoins require a GPU, but they're covered in another area of the forum.
Ok, what about https://www.nicehash.com/sell they offer to mine on CPU Maven It's possible to mine on Nicehash with pretty much any CPU but without specifying what CPU is on the system we really can't estimate how much you might earn accurately. Most older generation AMD cpus don't mine too well, though. You really should move this to the Altcoin Mining section, though- this is not about Bitcoin mining anymore. |

Are the EVGA SuperNOVA 1600 G2 80+ GOLD, 1600W PSU's going to be overkill for use with the S9? I realize they are triple the price of the
APW3++ PSU's, but they come with a 10 year warranty. My thought is that it's one less thing that has to be shipped back to Bitmain, if it fails.
I could buy 3 APW3++ PSU's for the price of the one mentioned above and just have spares, but if they are only going to last a year, I'd rather go with something that has a 10 year warranty.
I don't think I have much of a choice on the Antminer S9, because there is nothing else like it on the market. That's just a fact that I'm beginning to understand that I'm going to have to accept.
I dont see any reason to buy such an expensive psu. The AWPW3+ Is good and reliable for an honest price. Maybe in 2-3 years you will need other types of power sources, why spend so much on EVGA SuperNova? They can be used in regular computers, but imo I also think the AWP3+ is a decent PSU. It's probably going to be useful as long as miners use 6 plug connectors and you can use it for GPUs, but if you're using an EVGA, you can also power an entire GPU rig with the 24pin connector, molex, SATA, etc. The EVGA psu is based off of a Super Flower design so it is pretty quality, though. |
