I noticed that in about 1 month, BTC per day on CleverMining has gone down over 50%.

I was planning to set up a mining rig, but seeing a 50% drop in 1 month makes me seriously reconsider this idea.

Does anyone know why profitability has gone down so much, and any predictions for the future?

Thanks

Any chance of a more detailed answer on this?

The most PCIe slots I've seen on a motherboard is 6, for the asrock H61 and H81.

I've also heard that due to driver limits, there are only 6 allowed per motherboard.

So, I have 2 questions

1. Can you plug multiple risers into other ones..? E.g. a x1 riser with 3 x16s on the end, and then plug another x16 to x16 riser with multiple ones of those, to basically just endlessly expand the number of x16 slots?

2. Can you use virtualisation, such as VirtualBox, VMware, or Linux-KVM to get around the 6 GPU limit..? So, if it's a 6 GPU limit per 1 operating system, you just add more operating systems with virtualisation, and keep expaning endlessly?


Thanks

I know that altcoins are currently far more profitable to mine than BTC.

However, I was wondering whether there is a true reason for this, or whether it's just a speculative bubble.

There are 3 advantages I could come up with for altcoins:

1. Faster transaction time-- seeing as cryptocurrencies are volatile, if you were selling real world goods, the faster you can get it into fiat, the better, and so, faster transaction time could give altcoins a legitimate benefit over BTC.

2. Adding capacity-- if BTC ever got so huge that 8 decimal places is not enough, altcoins would provide extra capacity. However, this is a silly point, because BTC would have to get into the trillions of USD for this to be true. Not only that, but according to bitcoin.org, the BTC developers could add more decmial places if they had to.

3. GPUs are in better supply than ASICs. Because all computers need GPUs to show you a GUI, and because gamers like GPUs, there is a proper supply of GPUs. ASICs are in smaller supply. And thus, it becomes highly expensive to even maintain the BTC network, thus making altcoin mining cheaper to maintain.

In economics, value is created through demand-supply, and if it's incredbly easy to create an altcoin, how can it possibly have a true value?

What does everyone think? Is there any true value of altcoins, or it a joke?

But yeah, I mean, I see the predictable factors as

1. Your GPU's hash rate
2. The block reward
3. Time taken to block
4. Difficulty

And I see the unpredictable factors as

1. altcoin to BTC price
2. BTC to USD price

I do think, though, that the higher the volume of an altcoin, the more stable the value is going to be.

More BTC volume for an altcoin means that it takes  more people and more money to shift the coin's value, thus making the value more stable.

Yeah, and I've noticed that multipool.us checks every 1 minute for profitability, and switches you over on the smallest difference, and then it takes time to switch over, leading to lost Khashes and lost time.

So, this is why I've been wanting to find the best altcoin to mine, and only mine that one for prolonged perods of time (at least days, maybe weeks, months, years)

And so, this is why I posted this thread, because I thought that Dogecoin was totally random.

So, I think I should go have a look at the doge blockchain explorer, and I can see for myself how this reward system works..

If I have any issues understanding it, I'll ask you though, because you seem quite knowledgeable.

I currently believe that 2011 was the best year for Bitcoin, because it went up to $32 and back down to $1, meaning, you could speculate that it would rise to $32 again, and indeed, by 2013, it was up to $260... And so, with just a $1,000 investment in 2011, you could have made at least $32,000, and as it turned out, $260,000 and right into $1,000,000 when it went to $1000.

Not only that, but in 2010, mining wasn't profitable, due to BTC being so low in value.

However, I do believe that since the introduction of altcoins, starting with Litecoin, there is a potential to make a nice profit, not mega-huge, but nice, from minin altcoins.

I'm currently looking at TIPS, DOGE, LTC and NVC, based on the ones I've seen come up most often on multipool.us, but I have yet to decide which coin. I would also want to take into account difficulty adjustments and media hype. One advantage of DOGE is media hype.

Sure, but if you wanted to get cheaper GPUs via ebay, you would just buy a new one yourself, and then sell it yourself later on ebay.

That way, when you buy your card new, you know that it actually works, and you actually have a warranty.

I've bought 2 old computers on ebay before, and both broke as soon as I first switched them on. So, if the price drop was huge, and the ebay seller promised you a warranty, then maybe you have a point, but otherwise I'd rather buy new.

How about a scam where the DOGE makers mess around with the random number generator, and generate the maximum for all the blocks that they happen to be mining?

These coins are open source, sure, but I wonder if they can screw around with the code pre-compiling?

As far as I can tell, mining DOGE gives you a random block reward of between 0 and 500,000....

Coinwarz, in stupid fashion, estimates this to be 250,000 on average.

But we all know, in math, that random could mean, you actually get 1 DOGE coin every single time for 6 months straight.... like... 1 coin, not 250,000, not 100,000, not 500,000... Technically, you could get 1 coin per block for everyone to share amongst each other...

So.... correct me if I'm wrong, but I think it's logical to mine a coin with the same coin reward every time.

My theory is that the altcoin with the most volume on sites like Crypsty.com will be the best coin.

Because of the high volume, it's likely to have long term viability, and thus, it's less likely to lose value and less likely to drop off the map altogether.

Thoughts?

And where is this? URL?

As of 2014, a nVidia 750 Ti will make you around 2x the cost of investment within 1 year.

Clearly, scrypt mining is still profitable, but nowhere near as profitable as getting in on this super early. In hindsight, I would have had a WGET script archiving all news sites each day, and any mentions of "Bitcoin" would have gotten my attention, as a new word, and I could have gotten in on it in 2009, 2010. I did not do that, and thus, end up getting into this in 2014, with at best around 2x the return of initial hardware investment, which is very respectable as an investment, but nowhere near the big leagues of prior years.... Of course, even now, BTC could tank over night, or altcoin could disappear altogether.

So.... this brings me to the question... From my analysis, one way to get potentially huge returns it to mine a coin before it hits the market, and thus profit from the initial offering on Cryptsy.com....

I would like people's opinions..... How likely are new coins to be accepted on Crypsty.com, how many new coins are created each week etc..?

This seems like the perfect insider trading con for Crypsty.com. Anyone with insider info on Crypsty.com could see which coin they will add next, and profit immensely.

But assuming that none of us have inside info, is there any way  to predict which coin will be added next to Cryptsy?

Thanks

Do you have any sort of guide as to what is considered "too much" for the motherboard..?

Is it 75 watts per x1 and x16 slot, or is it something else entirely?

I know that AMD RADEON cards are 100 watts+, and so, I assume this is why they need 6-pin connectors, because x16 slots have 75 watts.

Is this correct? What is the amount of watts that x1 and x16 slots support, and does it change for PCIe 2.0, 3.0 etc?

Thanks

OK... but here's one interesting thing about the nVidia 750 Ti

According to this blog post, they only use between 30 and 40 watts.

So my question is, are they going to use 75 watts just because that's what the x16 slot is, or will they in fact use 75 watts anyway?

I mean, here is what I was planning

1x 750 Ti in the x16 slot
2x 750 Ti in the x1 slot, with riser cable

I presume that the overall power usage would be 30-40 watts x 3, which is 90-120 watts.

Would that really be too much for the motherboard to handle?

Thanks

Thanks

but if (2) and (3) are not an issue, then why would I want to get powered risers?

I am planning to use nVidia 750 Ti cards in my rig, which don't actually require any power other than that from the PCI-E slot.

I would like to ask, how do risers work?

I have seen the followng on ebay:

http://www.ebay.co.uk/itm/PCI-E-Express-x1-to-x16-Adapter-Extender-Cable-Riser-Card-Mining-Cooling-bitcoin-/251461244051?_trksid=p2054897.l4275

for only £6.99, you get a 26 cm x1 to x16 riser cable....

Here are my questions

1. Will this work wth my 750 Ti

2. How much Khash will this reduce from my 750 Ti, if any? It is said to do 273 Khashes on its default settings, with no overclocking etc

3. If I got a powered riser, would this remove any issues with reducing the Khashes

4. How do powered risers work? Are they powered by USB, or are they powered by 6-pin or 4-pin PSU connectors, or what?

Thanks

I've seen so many versions of the 7850, ranging from 860 Mhz core clock, 900 Mhz, 910 Mhz, 1000 Mhz

It's so confusing.

I'm just trying to figure out which is the best version of the 7850...

Thanks

I am looking to get an AMD 7770.

According to litecoin.info, these are the types of 7770s tested.....



first column is Mhs, 2nd is core clock, 3rd is memory clock...

But when I look for this item on websites like scan.co.uk, I get the following



As you can see, memory clock is 4500 Mhz.....

I don't get it.... Why is memory clock 4500 Mhz...?? All the ones on litecoin.info show between 1125 and 1425 memory clock... 4500 Mhz is vastly more..??

What is going on here..

OK. Thank you.

I used a PSU calculator on this website.. and I have entered in all my hardware info, and this is what it tells me....



It says that I only need 301 watts... and so, this looks good to me.

I do wonder though, if I'm going to be running the GPU all day, whether it's going to pull more watts than usual.

But otherwise, yes, I note your point that my PSU may not get what it claims.

However, the calculator gives me 50 watts to spare, so I'm probably OK.

Hi, I have found that the 7850 has quite good specs, and seeing as I've never built a mining rig before, I thought it would be a cheap enough card to give it a first go with.

My questions are

1. I have a PSU of 350 watts. According to litecoin.info, the 7850 only needs 100-something watts... but according to the official AMD spec, it requires 500 or 600 watts.... Why does litecoin.info report much lower watts, and what is the true watts required?

2. My motherboard is the Dell 0m017g, and it says it has 1x PCI x16 slot, and I've checked it myself to see a long PCI-looking slot... But I just wanted to double check whether this is the right slot for the 7850.

Thanks.
