Anyone know what this man is talking about?


I'm going to bet that it's milecoin, which uses the Ripple Network. I just learned about it today. I'm not sure if there's any reason to look into it seriously.

As for the actual wallstreetdaily guy, he has a newletter that he sometimes sells as the "Alpha Alert". I don't know if it's any good, but miles of text and no actual mention of what an item is looks like a waste of my time.

Travis Johnson dresses it down as misleading and not even about cryptocurrencies. It's a long and overdrawn ploy to get you to invest in a stock that has dropped in value 50% since October. He says:

So what is it? This is, as many readers have guessed, just a loooong and overly (and misleadingly) hyped tease about buying a stock called Points International (PCOM, PTS in Toronto).

My miners are still connected, but the stats site is still down. It's been about 20 hours since my backup pool sent some shares. Yep, Slush decided that was worth a single Satoshi. lol

How many S2's have they shipped vs the number of damaged miners recieved? Do you have the numbers, do we even know the scope of the number of shipped S2's? I imagine its a pretty big number.

From what I remember seeing on availability numbers on the Bitmain site, it has been between 1200 and 3500 per batch, so between 5000 and 12000 total units sent out to date, I would say. It's a lot, I guess, depending on who you ask, but not really. The S2 probably takes a good amount of time longer than the S1 to make.

You have no idea how badly UPS and other couriers handle 'fragile' items. If the packaging is done right the unit should survive courier.

I have always said that UPS hires gorillas and dresses them in men suits to throw, err, carry around the packages.

300 gh/s Avalon, a 19 hour block and a BTC reward of 0.00002856!!!  Might as well be an orphan.

Something's wrong with your stuff. I have only 200 Gh/s and my average block is .0045. My smallest block was .0034 for only an hour since the last and my largest was .0065 for only 29 minutes since last block.

I'm using an Antminer S1.

On the exact block you are talking about I got:

I couldn't give a rats ass about nanometers or "sexy" miners (seriously you guys need to get out more). All I care about is price, delivery, reliability, hash rate, and power usage.

I agree, but I would add one more thing. Size, if two machines are equal in everything, but one is twice as big as the other, I will take the small one, please.

You see, now we have seven blocks in one day. It's all good. Pool hop if you want, but you will only maximize your profits by luck alone. Hanging in any single pool gives you predictability.

TO SLUSH:

I hope you still check out this thread every now and then.

I have a few requests for the stats page. Can you add the following data points?:

  • Average time to solve a block
  • Average BTC rewarded per block
  • After the 25 or so on the main page, there could be a link to a CSV file that you update daily and contains the whole last month or three months or even a year.

Thanks. I appreciate your work for the pool and even more so for Bitcoin and its users.

Slush's total hashrate says we should solve a block ever 4 hours and 41 minutes, given a large enough time frame and assuming constant difficulty. This has proven practically true until recently.

The average time to solve a block in the last four days (15th through the 18th) was 4 hours and 54 minutes. That's exactly in the range I would expect, despite our recent 25 hour sojourn. Let's not forget that we solved 8 blocks on the 15th. That is a good deal above average. Overtime, these things even out. You might be tempted to pool hop, in hopes to avoid the lows and cash in on the highs, but that is really just gambling and might seriously backfire, like it did to one person who posted on the previous page.

I prefer to stay in one spot where my returns are predictable over the coming months.

On this forum you'll find loads of different PSU conversions.... Just one example of many:
http://www.rcgroups.com/forums/showthread.php?t=1750411

You'll need to jumper a few pins together... but it's really REALLY easy.
Then you can opt for another jumper (of 2 pins) and that will lower the fan speed.

Cool. Thanks. Some neat stuff there. And you can't beat that price per watt.

I'm using server PSU's. Dell 1570W one's. They power 3 ants... (2 oc'ed and 1 normal freq).... Can get them to work all 3 oc'ed... But it will take me some time... As the PSU has 5 Output pins which have a max of 312W per pin. I would need to connect the 5 pins in order to get the full 1570W out of it..without worrying that I will ruin my PSU. (Happened to some 930W one's I had...I wasn't aware that they had a max W on the output pins).

I didn't think to use Server PSU's. Yes, the price per watt is remarkably cheaper than your typical desktop PSU. Looking at pictures, I can't tell how you would be able to use this. Is there a breakout cable that attaches to the only port I can see?

Has anyone powered the S1 in unconventional ways?

Currently, the only way I have seen to do it is to use a computer PSU. I'm wondering about the use of a different kind of power converter for cases when you want to power an army of S1's. The overall goal is to reduce the price for each S1, which is currently the cost for the S1 plus a PSU. So far, it seems to me that it is cheaper to buy a 500 or 600 watt PSU for each one, rather than a 1200 watt PSU that can run two of them.

So I'm thinking of a situation where someone with electrician education has set up a separate line from the building main and then converted it accordingly and branched it to each S1. My understanding is that the S1 requires six 12 volt power lines and six ground lines. This sounds like it would not be too difficult to do and would be cheaper per S1, assuming you have over 20.

just a little fyi

8 pm marked my first full week mining with the S1 - hardly any downtime except for 2 hours when I moved it from home to a data center (where I have two 72u cabinets)

bitcoinx estimated weekly income at $418 USD - my first week was $488 on slush's pool.

By my math, you must have four or five S1's. Right now, a single S1 should average 0.1701 BTC per week (assuming overclocked to 200). At today's rate of about $615 you make about $100 per week.

Yeah, pretty slow on finding those blocks lately. Over a whole freaking day just for one block.

I was tempted to switch over to another pool, but I keep coming back to this one thing:

Your payout over time should be roughly the same, whether solo-mining or in the largest pool (assuming 100% up time and your hashrate is constant) ... theoretically. But when does it become practically ineffectual to mine in a certain pool? I have a single Antminer S1 giving me an average of 205 Gh/s. Solo mining would obviously be quite futile. The average time I would solve a block over a large enough time frame, assuming constant difficulty, is about three years. That is obviously not practical at all. Slush's total hashrate says we should solve a block ever 4 hours and 41 minutes, given a large enough time frame and assuming constant difficulty. This has proven practically true until recently.

So whether in Slush's pool, somewhere else, or even solo-mining, my daily expected average BTC income from my 205 Gh/s is theoretically constant. And that amount is 0.0243 BTC. And given constant difficulty, a large enough time frame (probably like 50 years or so), the math proves that my daily BTC mined is the same no matter where I mine. Naturally, I didn't account for pool fees.

Back to practicality, how bad would Slush have to get for me to leave? Well, if a bunch of miners left the pool the hashrate would drop, but the reward I would get per block would increase. I would still be rewarded the same daily average, but I would have less frequent rewards. For me personally, I would be content with getting .0486 BTC per block but only once every other day on average. That means good rounds would give a block every day, but bad rounds could last five days. Either way, over a period of three or four months, its probably not that big of a deal.

So, for someone who hopes to make the cost of his S1 back in two to three months, I'm gonna just stick on Slush, unless there are obvious, non-mining related issues, like poor server execution or whatever, or blocks are being solved less than one per 40 hours. Why 40? Because it's a little less than two full days and there's a biblical feel to it. For 40 days we wander mt. slush, in search of holy Bitcoin.

I have myself an Antminer S1, overclocked to 200 Gh/s.

I think it is overheating. The chips on the fan side are pretty hot, but I can touch them without it hurting. The chips on the opposite side are so hot that I can only touch them for about a second before it burns. From this side image (https://ip.bitcointalk.org/?u=http%3A%2F%2Fbitcoinmalaysia.com%2Fwp-content%2Fuploads%2F2013%2F12%2FIn-Stock-Bitmain-AntMiner-S1-180Gh-s-2.jpg&t=537&c=EIKKbM4jYKz2gg), you can see the pins in the center that I think are holding the heat sink on the opposite side. There is a grey paste oozing from them; I think it is thermal paste.

It has been running two days straight now, and the room temp is about 70F to 75F.

What is going on here?

...

3) 4BTC?  5 S1's cost ~4.96BTC, have less chips and no PSU.  This ain't a charity.

...

It still has to be a valid purchase though, the S1's made that and returned ROI reasonably quickly @6BTC ROI will be 9-10 months away.

Slush's pool just added 220TH here the last couple of days and dropped my return per block down by 20%. With more power being added, 9-10 months away is generous and in scheme of things is way too long.

I noticed that, too.

Just a few minutes ago.

It was only 840 Thash/s last week. I guess they finally broke that 1 Ph/s mark. Funny because I was reading a post there last week that was talking about finally breaking the 1 Th/s mark. The mining industry is what is in a bubble right now. BTC will be just fine, but there are going to be a lot of bankrupt miners at the unemployment office over the next few years.

I don't see why people are complaining about the price. Seems right in line to me. Maybe a pinch cheaper, like 5.9 btc, but it's perfectly reasonable. You get everything, plug and play, at 1Th/s. Ease of use is worth a little more in my opinion. Only draw back ... They aren't shipping tomorrow. They are shipping in a week or two.
bitmain is known to ship early, but even then, I will have received at least 3TH/s of S1's....for alot less although 2x the heat/energy.

If I had the money, I would be buying up S1's right now, too. Then I would likely be selling them to the come lately's on ebay in May.
