Mining profitability has decreased across the entire board and I suspect some ETH miners as well as people with cards that have less memory than the ETH DAG have started mining XMR. Unless price continues to go up, expect difficulty to increase or stay where it is. Mining has dropped down to about where it was before the mining craze in terms of profitability.

People boot rigs from 8GB+ USBs. Some lighter OSes may be able to run on 8-16 but unless you're installing more things than just the basics + the miners, there's really no real need for more than 64GB. Windows will need around 25-32GB but Linux can run on ~16.

I seriously doubt they're going bankrupt with all the miners they are selling every single day and the control they exert over Bitcoin and other chains. Bitmain does have support issues, though, I'd say wait a couple days and send more mail. Unfortunately they seem to be getting more crappy every day.

When people buy lots of hashpower price goes up. That's how Nicehash works, Ethereum's first major price spike is the most likely reason why profitability went up for a while then.

Site still looks like a scam and unless someone trusted can review this site and can confirm it works your best options are to buy from a forum member or buy direct by sniping a batch when it comes out. Most other options are scam sites promoted by people with one or two posts.

Added all 41 in stock on Amazon and they were all in cart without any problems. That's only for Newegg unless there's something else limiting how many you can buy. You can also ship to other addresses with more accounts, friends addresses/reshipping too.

Both are just fine for mining and the differences are marginal most of the time. After you get BIOS issues and all that out of the way, just pick whichever you like more. Windows is usually not free and although you can get licenses for under $5 nowadays, I still prefer Ubuntu for its simplicity and compatibility with pretty much all mining software.

For a more approximate exstimate, most of my S7s hit 70 decibels or more with a phone noise estimator app. That's pretty damn loud (enough to permeate through the basement to the living room without sound dampening). S9s are pretty similar in terms of fans so expect similar noise levels if you buy one. That being said, data centers are great for mining if you can't deal with the noise that miners make. Garage is also pretty good, but keep in mind a garage is extremely sensitive to temperature changes and it gets stuffy real quick in the summer. I only keep miners in the garage during winters, where temps drop below -10c a lot.

Peercoin is a coin you can mine and its profitability usually trails a little behind Bitcoin. With lower block difficulty and such it's a nice chain to solo mine on, but if you're looking for profit Bitcoin is where it's at. All the other SHA256D coins have unstable prices or are just plain not profitable like you said. I actually used to mine PPC back when it was slightly more profitable to mine on the chain about a year or so ago.

It's pretty nice for free electricity but due to being a 7000 series card it's going to pull a shit ton of electricity, make sure your PSU can handle it. They also run hot, if it gets to be too much an aftermarket cooler can help a whole lot. IIRC reference card blowers on the 7990s were pretty loud as well.

Kano is a pool I've been running on and off for a while and it's my favorite by far. I mostly run stickminers nowadays now that I've sold most of my S7s and such, but it's still fun to mine. Hopefully Sidehack delivers on his Bitfury gear so I can tweak some more

Seems resistance at $4400 is the only immediate thing on the horizon before we hit $5000. We've been bound to have a breakout soon either way with all the resistance and dumping we've been having in the past few days and weeks. $4300 may be possible tonight if we get a quick buy up of coins. Keep HODLing, friends.

Reddit's sub Buildapcsales is a great place to find cheap GPUs and the people there are extremely knowledgeable about discounts on various websites and figure out ways to maximize cash back from multiple sites; for example today there were prebuilts with i5 7400s, RX 480 8GBs and 8GB DDR4 for $500. I bought one just to scrap the GPU and sold the rest of the parts for a nice amount. Communities are great places to start bargain hunting.

Unfortunately it's extremely difficult to get your hands on one of those miners and many have tried to no avail. Sidehack's going at his own speed and it'll probably be too late for the Bitfury chips to be profitable at all, but he always designed hardware for hobbyists anyways. Bitfury hardware is difficult to obtain and you'll probably pay a premium for it if you get anything from em.

More likely the BIOS or OS itself not liking what's happening. Dual-core processors can handle 8 just fine, Intel or AMD. AMD quad core Phenom processors can be found quite cheap, and for newer sockets the G3930 is around $40, and the new Athlon X4 950 has 4 (Excavator?) cores on a budget.

Is it that hard to move a thread? Below Bitcoin Forum in the bottom left of your screen there is an option to move your thread. Save the moderators some time, they've got more important things to do

Any blocks yet? Seems like a nice chain to mine on if you've got some Compacs or something similar, better odds than BTC and if you hit the lottery you still get a nice reward. I'll probably reconfigure my USB farm to BCH when I get back home, I don't like the chain in any other way though :/

The way things are going right now not surprised spread is pretty large. I guess EDA is just a "feature" of BCH now and it's just a cash cow for miners. At least it's delaying difficulty rises somewhat for us regular miners.

I believe some Chinese sellers are selling 750tis that are actually rebranded 9000/400 series cards with 1GB of GDDR5. Haven't heard of any more recent bootleg cards though, most are just similar cards with reflashed BIOSes or custom ones to reflect the fake card's name.

Difficulty will probably continue to be turbulent but I don't think it'll be negative this time. Great to see that the game is still up and running though!
