What’s the Return on Investment From Mining?

Nowa­days a lot of ar­ti­cles talk about the end of crypto min­ing. But sta­tis­tics on Google Trends shows that peo­ple are still in­ter­ested in this sphere. Of course, the ROI isn’t as big as it was, but you can still make a re­ally neat profit. So, how can you cal­cu­late the ROI? You should count the cost of your min­ing equip­ment and today's day-time rev­enue or in­come with the de­duc­tion of elec­tric­ity costs plus main­te­nance fee. So if your min­ing equip­ment con­sumes 10kW per hour, you should mul­ti­ply 10 by 24 hours and by $0.15 (Your elec­tric­ity price) in order to find out the costs of elec­tric­ity per day (in­come minus (elec­tric­ity costs plus main­te­nance fee) = rev­enue). Then you can mul­ti­ply rev­enue by 365 days to see if it pays off in a year’s time or not. And if it does pay off in a year, then the in­vest­ment is good, be­cause in that time you start earn­ing money and your equip­ment works only to gen­er­ate your profit.

TOP TIPS TO MAKE MINING PROFITABLE IN 2018

Early in the year of 2018, mining was profitable enough and the only issue for miners was to obtain the video cards because almost all of them were sold out or extremely overpriced. For example, in January the price of the RX580 card was about $600. Nevertheless, during that gold rush, people mined whatever they like and bought video cards of any type, because it was profitable. If you managed to get the video cards at a low cost, you could earn money, big time. When the profitability started to fall, mining began to transform into smarter mining. It means that it’s less difficult to obtain good equipment at a reasonable price but this means that now we have to be smart about how we mine.

P104-GIGABYTE GETTING MORE PROFIT FROM MINING BY FIXING VENDOR'S MISTAKES WITH SOLDERING

Today we're going to tell you how we tried to solve the problem of overheating of the memory power supply unit of a p-104 type GPU. Overheating can cause significant damage to a rig's reliability and service life. GPUs of this particular type often produce so much heat that it just burn. This issue is really critical for those who aren't just going to try mining for a day but try to build a rig that would work steadily for at least a year.

WHY DO CRYPTOCURRENCIES FALL IN PRICE?

Let’s take a philosophic look at this: people always tend to look for a reason. For example, to understand why one asset goes down in price over another? However, for the most part, it is very hard or even impossible to establish the exact reason. And it’s also extremely difficult to discuss such reasons and to assess why it is the case. It should be pointed out, that very complex processes are taking happening all around the world. For example, one can research the impact of a growing hedgehog population in Australia on the exchange price for a dollar in Berlin. In general, this doesn’t suggest that there is any correlation, but someone could have just looked at the hedgehog population graphic and the dollar exchange rate for Germany and found a similar pattern between these two cases.

GPU MINING IN HIGH TEMPERATURES

Optimal temperatures are different for different components. - Unrecommended temperatures are always indicated in every technical document of the component (also, maintenance T, storage T, storage and maintenance humidity, allowed altitude). - Optimal temperatures - from the dew point (the lowest temperature at which condensation condenses) and up to 21-26C (usually, indicated in the passport). Capacitor is the most suffering element in hot temperatures. Electrolytic capacitors are widely used because of their low cost. You can take a look here what happens to them when they overheat. - Accordingly, unrecommended temperatures are the ones higher than indicated in the technical passport. - Using your devices in high (or low temperatures) may lead to premature failure (at high temperatures there is an accelerated degeneration of semiconductors and destruction of the elements) and change of embedded characteristics of the whole rig or its parts (the most usual example - decrease in the maximums frequencies).

DIFFERENCE OF MH/S IN LIQUID COOLED AND AIR COOLED DEVICES

We announce the hashrate of Comino Grando - 540MH/s, where variation of +- 5% Mh/s is expected. Hashrates can’t be compared on air cooled and liquid cooled devices. They also can’t be compared on the devices manufactured professionally and assembled at home (though, I know that many of home-assembled rigs show amazing results). Liquid cooling allows to remove the heat from all three modules, while standard air cooling removes the heat only from GPUs. That part of a radiator contains some small copper parts. The other parts are coated insignificantly or not covered at all, sometimes being in contact with the radiator. While mining, as you know, memory and PSU are actively used. When the miner claims that the temperature is 66C, most probably it was taken from the GPU indicator, which is placed in the GPU processor. At the same time, memory and power block can be overheating (100C or even higher). If you google GPU thermal imaging, you’ll see the whole picture. When the system’s memory and power block overheat, GPUs start giving out errors. With time, microchips are starting to degrade. There are cases when after a year of mining microchips burned or degraded by 20%. In our case, all three modules are equally cooled. We pay special attention to the VRM and microchips, they provide a stable longterm operation on high frequencies. Using thermal imaging, we can see that with the outside T 36C, the temperature on all the modules does not rise above 60C, with outside T30C - not higher than 60C. With that, we achieve high hashrates and stable long-term operation. In addition to that, we use all the top level components in our devices by world's leading manufacturers, some of them are customized especially for us: Molex for gold-plated sockets for our custom raiser cards, modified PSU consists of server components for the system to operate at full power in 24/7 mode. We are partnering with Asus, Gigabyte, Nvidia, AMD, Delta, TSMC, Hardware Labs and others. Btw., our last test showed an upper limit of 34.9Mh/s for 24 hours. But, you don’t want to run it long-term.

IS THE COMINO N1 MINER THE APPLE OF MINERS?

Bitcoinist.com did a test drive of Comino and here's what they say (among lots of other nice things): "The inside of the machine is incredible. All the parts are designed and manufactured for this miner, specifically, and everything is in just the right place. There are no loose cables or noisy fans. Everything is just where it needs to be and is served by water cooling, making for silent mining."

COMINO EXPERT COMMENTS

We are regularly receiving questions and comments regarding radiators in our liquid cooled products: - why do we have only one radiator for five water blocks? or, - one radiator would not be enough for my 6x1080 water cooled rig We use a radiator similar to this http://hardwarelabs.com/nemesis/gtx/360gtx/ exclusively modified for our Comino N1. This radiator has a very thick finning and can conduct up to 1500w of heat. Which is more than enough in our case. Plus - solid performance tuned for low speed fans. In practice, it can also easily handle a 6x1080 (FullCover) with a Laing DDC 1TPllus pump. Some techs: 120 mm x 3 fan Xtreme form factor two-pass radiator 398mm x 133mm x 54mm (L x W x H) 16 FPI 25 Micron Copper Fins Now optimized for sub-800 rpm ultra-stealth fans Supercruise optimizations for scalable performance with higher speed fans 15% more tubing area in the same Black Ice® GTX™ 240 form factor Increased internal coolant flow rates Standard G 1/4″ inlet/outlet fittings Standard M4 mounting threads Compatible with Black Ice® Xtreme III, Black Ice® GTX™ 360 radiators Custom Dark Matter™ high quality finish Fully ROHS Compliant 100% Made from conflict-free materials Industry standard Black Ice® quality Lifetime warranty against manufacturing defects* It is a dual pass radiator, but not in the traditional sense, where the coolant flow path is side to side or U flow. Its flow path is front to back OR back to front depending on which port is used as the inlet. In other words the coolant travels up the tubes the full width of the radiator core then changes direction in the non-port tank and travels down the other set of tubes on the opposite side of the core. To get this flow path to work they have installed a plate and tube in the port tank ends. A professional product, though, not very common for a regular user, building rigs. Therefore, the price may be on the premium side, but it's not unreasonable for a radiator that is not outsorced in China.
