I had completely forgotten about that. A few years back I'd gotten an email from my bank asking if I wanted to link my Coinbase account, to my bank profile. I went back to double check, I hadn't used that bank for any transactions.

In the long run if people can develop a significant ecosystem beyond mining, and speculation the pump won't be so bad. Otherwise it's best to guess how much their fiat pump is, and when the note is getting called in by the banks.

I'm not going to waste any more time on them, I'm just going to close the account.

There isn't a good one that I would trust with large transactions. I hate saying that. I've used Cryptsy, Xapo, Kraken, Poloniex. Even Bitfinex before they made really nervous. While I've never had problems with any of those. I've never given them the opportunity above 1-2 BTC at a time to make any problems. I would say trust your instincts but that hasn't gotten me very far with Coinbase lately.


There isn't a whole lot else to tell. Other than at one point they told me it was a common bug that was occurring, and had me go through setting up margin trading on GDAX. They said the solution was to toggle the margin switch back and forth. I really didn't want to do it in the first place, but it didn't work. When they split everyone's wallet for GDAX, a lot of these types of problems started occurring. I totally understand they make a lot of money with Wells Fargo from it, but they're killing themselves with it as a reliable exchange. The best I can tell they've been buying into the sales pressure they monitor on Coinbase, on credit from Wells Fargo, and probably these "lost transactions" as well. At a minimum I would not do business with them again unless they separate the two ventures. Pumping a big fat blow up in your face bubble. If you have a Coinbase wallet, you also have a mirror GDAX wallet.

I've put in several support tickets since April regarding a Litecoin transfer which shows in my transaction history but doesn't allow me to access the Litecoin. I've been buying, and selling bitcoin on here for 4 years, and so I wanted to make sure you understand that in my opinion you have flushed your name straight into the garbage. If you cant handle basic transactions for customers, you shouldn't be messing with money. It's really that simple. It's not the margin switch, or my browser, somebody needs to look at the transaction.

Yes hi I understand you're new to the issue. I had a Litecoin as in 1 LTC
which still shows under that transfer ID and transaction hash, but I am unable
move/buy/sell/trade with it. It was really a shame because this was a test
LTC that failed, and as a trader ended up moving hundreds of them with
other exchanges while this ticket has been open. You know it's been
averaging a month between responses for some time, and so I hope you can
understand why I have no faith in Coinbase anymore and why I share the
story with other traders.

Thanks,

The Litecoin I sent still shows under transactions but I can't do anything
with it.

I sent 1.0 LTC, as a test which was confirmed by your email system, but it doesn't show up in my account. It was intended for GDAX. When you find it, can you also let me know if the address is good to send to in the future? Thank you, https://live.blockcypher.com/ltc/address/LRte1L2UuC49t6yeBmP5rsPkkixRnkVSWH/

Hey thanks to everyone for the support. It's been really frustrating so I kind of took a crypto break. To be clear it's 1.0 LTC I was able to see the transaction come in on the block chain. https://live.blockcypher.com/ltc/tx/9a4458dbbb27a9f04b13023a9aef6220322a34f80aeb3c6bfba5200bd8c23b3b

Then I got the confirmation email from Coinbase that it was received. From that point forward it just shows as pending in my Coinbase wallet with the 60,000 confirmations.

As far as the people not having issues with Coinbase, yes I understand that. I've had an account with them for over 4 years, and haven't had a problem with much larger transactions. I am explaining why I have lost faith in them entirely despite that fact.

The two biggest concerns that I have are that they don't understand the issue, and it's clear that the litecoin continued to move from then on. I thought at first it was just moving to cold storage, but I'm not sure now. I mean they literally emailed me that they don't understand what the problem is. It's possible they've become entirely inept at dealing with Litecoin in Charlie Lee's absence, and it's still there somewhere. It's also possible that someone is stealing Litecoin on their end from the hot wallets, and they really don't know what the hell is going on. I have another ticket open with them, I think 4 months is a little excessive, and there's still no resolution of any kind. That's why I would not do any business with them in the future.

I've been trading on Coinbase about 4 years. I sent a Litecoin back in April as a test before sending the rest, and it's still pending on the Coinbase end after 4 months. After several support tickets, and trying to call I gave up on them entirely. It shows up with over 60 thousand confirmations, and they just completely ignore me. I'm not the only one that's had this happen in recent months. They have quickly turned into the worst exchange available. I'd heavily advise against trading with them. If you have an account with them, move it somewhere else, or offline.

I've been trading a while. I didn't lose money at Mt. Gox, I think I was on Cryptsy at the time. I lost a little on the Bitfinex hack. Anyway, my bigger concern has become the exchanges are not just exchanging anymore. They've been making clear manipulative movements that I think will ripple out like Mt. Gox as loss of confidence if nothing else. Also, the iFinex vs. Wells Fargo lawsuit is possibly revealing the relationship between Coinbase, and Bitfinex. For the record I already hated Wells Fargo, but the first thing that stuck out was the jurisdiction section that mentions officers and offices in San Francisco, Coinbase HQ. They also share very close offices in the UK, where Bitfinex holds Tether, and Coinbase process CC tx. I think it's common knowledge among most BTC users the banks are tied together, but not the exchanges? It's possibly a stack of giant coincidence. There's a little Jerry Fletcher in my head screaming this is going to unfold all bad for the BTC/USD pair. That's my 2 Satoshi, I'm out for a while.

Yes, frequency of 1000 gets 16GH/s on a 16 chip board. I'm suggesting that measuring the junction between the heatsink and the chip is easier and reusable for reference measurement. I wasn't sure if you were talking about using the MCP9700A to take that measurement for reference or building it into your design.

They're all 16 chip boards. I misunderstood your logic as entering the frequency yielded a specific hashrate. Yes, the frequency seems to correspond with the number of chips on board. When I switch the boards out they yield the same hashrates so something is going on with the power supply or operating system I'm not sure which yet. My step up transformer that runs my 220V BGA station went down so I had the chips placed professionally at Mastek Innerstep, which by the way if anyone wants professional chip placement I already paid for the stencil I think they want $25 a board for 16 chips but the stencil would work for less chips obviously. PM me for contact info.

I don't have a lot of USB cables so I wan't sure if one was messed up or not. I'm just shooting darts for the difference between my two sets of boards. I figured mabey high data transfer coupled with lead resistance. It doesn't matter, like you said I used a 6 foot PS3 controller cable and nothing changed.

If someone blows up a regulator please post details In the mean time I'll keep stepping up a 16 chip board to blow one up on purpose and report back. My better thought is to lift the inductor used for the overcurrent protection and take AC and DC measurements there.


I've taken these measurements for several companies, you can't do anything about the inside of the chips to the best of my knowledge but most models suggest platinum with 4 wire yields at least +/- .1 C I think. You take a thin strand of platinum that's zero to at least an ice point reference and a span of 100. Then you thermal paste the platinum in between the heatsink and the chip, any exposed platinum must be insulated. Or you can buy a thin film prt also platinum that's already charted and hook it up to an Agilent meter and something like Benchlink.

You build a model of the metal instead of the system so you can reuse it. Really you can just weld (not solder) the tips of any RTD together as long as you have an idea of the composition, and do the same thing as long as you can generate ice point and 100C. It's probably only worth it if you're going to build a lot of boards. I have one set up to control the heat for an infrared reball station in my shed as well, it's pretty accurate. I favor my hand because it's easier. I was just curious how many days you've had them running at 35. 

I've been using your firmware and found personally this isn't true at all. I'm still around 1280 .94V, my two boards running on Debian run around 10 GH/s. The other 2 on raspberry pi, Archlinux run at 17 GH/s. The bfgbuild, drivers and firmware are identical. I've confirmed these speeds on both multipool and givemecoins.

Can someone confirm that shorter and higher quality USB cables yield higher speeds? I'm not entirely sure yet but this may be the most cost effective upgrade you can make. I also appreciate the change to the LED.


I agree, I'm considering moving the regulator to a breadboard in an attempt to get a more accurate measurement of the output current unless someone has a better idea. An easier method might be increasing the resistance at Pin 11 (sense +) through TP1 on the regulator and measuring the change in voltage to get a better idea of the output current. Things like that work in my head, but don't always pan out in the real world. Have you had any regulators fail yet?
 

I favor the method of holding my hand slightly above the heatsinks, I've suspected via IR gun that the reported 25C is closer to 30 on my boards. I might be able to borrow a slim PRT that could take this measurement pretty accurately. Like you said all temperature measurements utilizing resistance in this method are approximate. Utilizing a 4-wire resistance and an ice point reference is probably the cheapest. I cut up a 10 ft hunk of aluminum C-Channel from the Home Depot and thermal pasted it

Is there a way I can get a live current measurement in parallel between sense+ or TP1 and sense- on the voltage regulator?


I originally had pull-up then I edited it to pull down. I think it is pull up anyway, one device = bus driver. The rest of the devices = bus passengers or "slaves" even if it's one. The resistors keep the slaves clock and data line in time with the master. I think it's referred to as a wired logic connection. I'd guess it would work with the resistors on the board just between two the way you said. Why would you go through the trouble for just 2 boards though?

It's DVDD adjustment right? Ideally the maximum hash rate you could get would be around 1.1V at 2A Iop, Frequency = ? Or .9V per chip still around 2A Iop if you are going for efficency, Frequency = ? When you came up with the 4A per chip were you measuring the operating current per chip or measuring the power consumption of the board? I also noticed you're chips running at 35C, how long have you been able to sustain that?

I didn't try hooking up two boards together like you were saying. (I'm not saying that wouldn't work, I'm not sure actually) It works using the schematic in a master slave effect. You need the pull-down resistors on SCL and SDA to create the logic 0 on the chain.

I concur I'm lost as to what this would be set at ideally or if it even matters between .9 and 1. The best response I've found is around .940 1640:70 into BFG. What do you set your cards at form?

Also wondering if anyone has interest in my jacked up card? Whatever is wrong with it isn't obvious, it connects to BFG miner but won't do any work. I know it isn't the ASIC's because I have 4 others assembled in the same manner. Anyway, I'm tired of messing with it.

I had seen Ost mention using 1.025V. I don't see much of any difference between .9 and 1.025. Wouldn't it make more sense to keep it around .9V?

I just hardwire the fans full speed. Am I reading the chipset datasheet wrong or would stock setting be 1V at 500-1000 MHZ?

One last retarded question before I move to the chain. The fifth board is bothering me. What 2 points are you measuring to adjust voltage? TP1 to ground?

Im interested in giving this a shot. I hope no one saw my original comment it was seriously retarded. I can breadboard it out. The design below the ISP on the schematic is reference for the chain right?

It turned out the request work updates were due to a short in the board. So 4/5 running not bad I guess. I am having a strange issue with the raspberry pi. It doesn't seem to like more than 2 of these connected at once. The cards aren't bad because I can interchange them. Anyone else run into this? Mabey, just too much for the little guy.
