I dare say that in many situations, an aircon running on heating would be a better heater than an old miner, because of typical COP, eg. using 1000 watts to do the same amount of heating as a 3000w fan heater / oil heater / miner. Not to mention floor space usage / noise.
Eg. a miner that's 96 TH/s, 2400 watts, 1.5% pool fee, would lose about $3.14/day @ $0.15/kwh power cost, compared to a small aircon using say 800 watts to pump 2400 watts running 24/7 would cost about $2.88/day (of course if your aircon never stops running, it's undersized.)
Modest/excess wattage spent on lotto mining sounds good.
Depends on the use case. I am sitting in the back room of my condo with a 1 board S9 at the moment keeping the temp here above 72f [22c] BUT since I have 1 zone heat I get to keep the rest of the place at 66f [19c] I just have 1 zone heat / aircon for here so although a lot less efficient, it is cheaper to run. In the bedroom I have a 2 board 400w give or take L3 running on a LTC / Doge lotto pool. So far got a few doge blocks over the last couple of winters. But when I am sleeping I am not heating the rest of the place. I rotate through old miners depending on what is working and if I have sold any over time. -Dave How much BTC are you making per one week of leaving it on? What pool do you use? It's not on all the time, depending on the outside temperature and a few other things it's on at most 1/3 of the day. Figure it's generating about $0.30 a week on ViaPool BUT it's not for generating money. It's about spending less money on heat. 300 Watts is 300 Watts I can turn it into heat with a space heater or I can turn the same 300 Watts into heat and a few cents. By the end of the winter I can buy myself a lunch. With the LTC / Doge lottery pool I would have been better just PPS mining somewhere, but it's not as much'fun' -Dave |

Has CF patched that WAF vulnerability yet? Seems it was enabled around the same time as this exploit was announced, I'm pretty sure it's been around a little longer though as it was attempted on 1splitkey last month. A bunch of other sites that I deal with, mostly non crypto related are also dealing with the same issue. I'm guessing CF did not so patch it as do a quick and dirty work around and will fix it later. If this is the final fix, there are going to be a lot of people with a lot of apps that are going to be really annoyed since there are a bunch of API calls and other things that are not working at the moment. You wind up with the question of 'is a broken CF better then nothing" -Dave |

There are a few of "App Wallets" working on NFC support for both COLDCARD Mk4 and TAPSIGNER/SATSCARD. Like the years we had to push PSBT to be adopted, we expect NFC will take its time too. Not in a hurry. Nunchuk has integrated it well for both COLDCARD and TAPSIGNER/SATSCARD. It's working fairly well with the latest version and they keep on improving it.
Our approach to NFC is simple, almost anything you can do with the MicroSD/USB you can do with the NFC (signing, exporting data, etc...)
Cheers.
Thanks for the information about Nunchuk, I never heard of that one before. I will definitely give it a try, since NFC was the reason to get the MK4 and not the MK3. Honestly I think NFC is not a necessary feature and will probably even scare people away from buying the MK4, but since it is there I want to give it a try. What I dont really understand is, why you can scrape away the NFC link on the PCB, since it seems like an attacker could easily replace this link if he has physical access to the coldcard. In any case I like the coldcard so far and use it regularly. Scraping away the NFC means that if something went horribly wrong with the programming of the coldcard or there was a vulnerability found with NFC it could be disabled without destroying the unit itself. Or if you are just did not want any way for the unit to ever transmit anything. However, if someone gets physical access to your unit and there is another security issue, if the chip is active or not or even there or not makes little difference. The ONLY situation that would matter is if they got access to your coldcard, reconnected the NFC and then figured out a way to be near enough to you to get access to the radio waves in a way that they could do something with your funds. At that point see $5 wrench attack, quicker, easier and it just works..... -Dave |

For the most part he did not donate to people he donated to groups. And it's unclear how much money he has left.
If someone wants to believe him after all, he stated in the first interview that he only has about $100 000 left in his private bank account, and even that he has some other assets that can be seized and sold, I think that investors can hardly hope positive outcome in terms of compensation for damage.
Its even more surprising considering his parents are lawyers and professors at Stanford Law School. Or maybe that's the reason he was so cock sure, knowing that his mommy and daddy will get him out of any trouble.
I would like to be wrong, but Bankman is not one of those who go to prison for a long time, and even if he is convicted, somehow it seems to me that he will receive a small sentence and accommodation in a prison that will seem more like a hotel. If you just take the example of our country and all the trials that were conducted and the people who were convicted, how many of them ended up in prison? The system always takes care of its people, I think it's the same anywhere in the world. Depends if he takes some kind of plea deal I can see hum not getting a long sentence. He takes it to trial and drags it though the courts I can see him getting nailed to the wall in terms of time. As for 'Danbury Country Club" prison vs. a supermax. That's just the way it is. You don't need to put people who are not a danger to others and are a low escape risk in a facility that costs more to maintain in general and costs more per prisoner to operate then needed. The issue becomes a plea deal can save everyone time and effort and money. We can argue over if they should exist and how they should be handled but in the end it is what it is. Also, keep in mind, it's not just the US other countries want him too so 1st he goes though the US justice system then others may want to get him. Which may be why certain things were expedited in an attempt to get him to the US. 1st come 1st served. Now every other country who was working on a case has to wait... -Dave |

Starting with I can't find your source code and the site will not work if it's not connected to the internet so it's dangerous and insecure and until those are fixed nobody should use it.
Interesting concept but you are advising people to print it on paper and now requiring a multi-step process for recovery.
Since it's free it has that as a major advantage over a hardware wallet and some sort of metal seed holder. But, it's on paper which is vulnerable to a lot of damage.
Not a hit against what you are doing but IMO more secure seed storage is going to be better then a more complicated way to write a seed.

Very surprising. There are a lot of hot issues right now in the cryptocurrency market.
I am curious now about the arrest of Sam Bankman-fried. Could this be a guarantee that users' funds on the FTX exchange will be refunded or given to the user back? The arrest of Sam Bankman-fried, could be a huge W for some people who lost their funds on the FTX exchange, but I am praying that these customers' funds must be given back to the customers.
What funds? They were spending everything everywhere. Everyone will be lucky if they get a few pennies on the dollar. If there is even that much left. If I am perfectly honest I did had my doubts this day will come as the guy has donated too much money to important figures and he has probably the best lawyers that his money can afford him.
For the most part he did not donate to people he donated to groups. And it's unclear how much money he has left. Actually I wonder why SBF got arrested? is there any rule he broke? but I can't find any laws that he broke.
Bank fraud, securities fraud, and a few others. -Dave |

The 2 things are different.
1) Money laundering is tough to prove if they are doing KYC in some real way and keeping records and tracking and everything else it is a somewhat easy fight to win.
2) Sanctions violations, from what is being discussed is a lot tougher, you move 1 doge for some sanctioned business / country it really comes down to a yes or no answer. Did you allow an IP from North Korea to open an account, and trade 1 doge for something. If the answer is yes, you violated a sanction. [Yes I know you can't just sell 1 doge making a point]

.....after 2025 BTC , ETH and so on will be worth real 0......
Nope, many places have flat out banned all crypto transactions and the holding / using of crypto. And wait for it.....nothing happened. The EU can ban it, and wait for it....nothing will happen. It's like banning anything else, people will do what they want to do. Unlike banning something like drugs, having a piece of software on your phone / PC is a lot easier. -Dave |

I understand the 1 2 3 8 16 32 64 numbering.
But it makes you wonder why CM did it. I am sure there are other BTC0.128 chips out there, but I would imaging that there are several orders of magnitude more addresses with BTC0.1
Just for anonymity using more common amounts would be logical. With that in mind @LoyceV how difficult would it be to see how many BTC0.1 BTC0.2 BTC0.5 BTC1.0 and BTC2.0 addresses that meet the criteria.
i.e. I don't care about an address with BTC1 if it got 4 deposits go get there, so the same as how CM would have done it vs their amounts.
I could probably download your data and have one of the programmers I deal with whip something up, but if you have something close to it already it might not be worth it to have them do it. Well, that's disappointing: I don't know what happened, but my output data isn't exactly the same as I got last time. I replaced some of the values (0.128 turned into 0.1, etc.), so I can't compare all data now. I was hoping to reproduce the same results, but also don't want to dive in deeper so I can't tell what went wrong. The numbers I checked were about 40% higher. That being said, it's very clear there are much more "chips" with round numbers. I'll run the data again with a more complete data set, but it's going to take a while again. Debugging software can be fun. :-) And the things that take hours / days to run before giving an error are even more fun :-) Or not..... 1 BTC chip = 20 shilling chips
1 shilling chip = 12 pence chips
1 pence chip = 2 halfpennies chips = 4 farthings chips
may use half and third and quaret farthings if BTC price go up
Yes, but just pointing out that at least with things like BTC / crypto in general .01 or .0025 or anything like that just seems to be a bit more what people are expecting then 0.128 Not saying one is better then the other, just at least in my view it is what people are expecting. -Dave |

Need a lot more information but probably not enough space and airflow.
How large are the windows? Can you but in large loud high speed fans?
What is the average humidity? Higher humidity will cause issues if you are just opening the windows rather then running the air through some form of chiller.
Design of the space? An open square is different to cool then a long rectangle.
Ceiling height (heat rises spacing the miners out will help a bit)
Will you need sound baffles? What is nearby that may cause problems due to the noise of 100 miners screaming away.
And so on. The forum can only get you so far, you will need a talk to a local architect and engineer to get the rest of the way.

As everyone keeps saying, they will NEVER ask you for KYC on testnet.
AND since you are setup with them and they have your info anyway, anything you are doing with them that tracks back to you / your email / other info will probably *NOT* get a KYC request either. They know who you are already.
Any transaction I make that tracks back to ANY of the emails I have on file with bitpay never gets KYCd anymore as far as I remember. Don't need to have someone tell them what they already know.

All these layoffs were announced months in advance before they happened, and I already wrote in one of the threads where we discussed that all these companies first try to cut their costs by laying off as many people as possible, and then forcing those who remained to work at least twice as much. This is quite a common occurrence in a capitalist society where money is God, and company owners are some kind of high priests who serve it by exploiting those at the bottom of the pyramid.
I do not think that this is a bad sign in the sense that all these companies should be seen in the light of possible failure, because we can hardly expect that all these companies are managed in the way that the famous Mr. Bankman does with his company. In other words, to destroy a $20 billion company overnight, you still need to have a certain amount of skill, and we don't see such people every day, do we?
Agreed that it might only be a contraction of the business because it needs to adjust to the contraction of the cryptospace, however, is this really okay? Can it not also imply that the condition of the business is questionable? We can never suggest that those exchanges are financially safe in this bear market. In any case, this article about Crypto.com's CEO. It appears that mainstream news media are researching on the history of the important people in the cryptospace and finding red flags. Kris Marszalek wants everyone to know that his company, Crypto.com, is safe and in good hands. His TV appearances and tweets make that clear.
On Friday, Crypto.com published an audited proof of reserves, attesting that customer assets were held on a one-to-one basis, meaning that all deposits are 100% backed by Crypto.com’s reserves. The audit was performed by the Mazars Group, the former accountant for the Trump Organization.
While no evidence has emerged of wrongdoing at Crypto.com, Marszalek’s business history is replete with red flags. Following the collapse of a prior company in 2009, a judge called Marszalek’s testimony unreliable. His business activities before 2016 — the year he founded what would become Crypto.com — involved a multimillion-dollar settlement over claims of defective products, corporate bankruptcy and an e-commerce company that failed shortly after a blowout marketing campaign left sellers unable to access their money.Source https://www.cnbc.com/2022/12/09/cryptocom-kris-marszalek-involved-bankruptcy-offshore-holdings-client-money-monaco.htmlHis history does not really look that bad, just that he tries to cash in at the end of the wave cheaply and quickly. The USB thing is a perfect example, looking at the dates in te article he got in as the market was being flooded with cheap USB / sold state storage. Newer better ones were all over the market and better stuff was coming quickly, he went after the crap low end. Same with his other services, undercut everyone and either make a little money OR hope to get bought out by the big guys. Looks like he finally did find a winner with Crypto.com, only time will tell. But as always. Not your keys, not your coins. -Dave |

3 things.
1) You have to download and install bisq and do a few other things, there is no 'create an account' you have to have it running on a PC you control.
1a) I don't think there is a BTC <-> XMR on bisq
2) besides that 100% what BlackHatCoiner wait at let things sit for a few hours. If I am looking for you and know you are going to be moving coins in a certain time frame tracking becomes easier if you are doing it all within a few conformations. Get a beer, catch a movie, take a nap, whatever.
3) You are going to pay a lot in fees unless you are talking $1000s of dollars it's going to be a large % of the BTC

No need to do a proxy, wireshark https://www.wireshark.org/ works wonders you can monitor just about everything going on in your network and it can rebuild conversations between source <--> destination quite well. There are also some tools that require a bit more work that can give you more information but they do require a bit more work / knowledge of networking. Depending on the network switch you are plugged into you may have to change a few things to see all the data. -Dave |

It kind of misses the point though. It is trivial to identify an output as coming from ChipMixer. Take a look at this address: https://mempool.space/address/bc1qu225m44ere7sy89x5z0qhrhp7ma0yttrpwnyuh. Now, you can follow the coins on that address through dozens of transactions. Each transaction creates 30 outputs of the same chip size, and one change output. This chain of transactions creates hundreds of outputs for ChipMixer chips in total. There is no other service out there which does anything like this. It is completely unique and trivial to identify. This would not change if the chip sizes were 0.001/0.002/0.005/0.010/etc. instead of 0.001/0.002/0.004/0.008/etc. The whole point of ChipMixer is to break the link between coins you deposit and coins you withdraw. It is not to hide the fact that you have used a mixer, and indeed, often the exact opposite. Being able to show quite clearly that all my inputs came from a mixer means I can prove that any claims you make about my coins being "tainted" or any other such nonsense are provably false. This same logic applies to coinjoins. Yes and no. I have made many transactions that create a lot of .001 (filling collectables) and back in the day when BTC was a lot less I made a lot of BTC1.x into a bunch of BTC0.1 coins. So although not as obvious a the 30 groups that CM makes there are probably (waiting on loyces program to finish running) a lot more of those then .128 which was why I bought up the point of probably orders of magnitude more. More a thought experiment then anything else, but still going to interesting to see what the results are. -Dave |

To me being a merit source would probably make me feel like I have to go out and send merits. More like an obligation.
Yep, it does feel like an obligation--but truthfully I can only speak for myself. Other merit sources have become inactive and maybe don't feel like it's a "job". The only reason it seems that way for me is because I'm an ardent supporter of the merit system and I want to keep the merits circulating. Which may or may not be part of the problem. If sources go inactive and are not replaced the flow may slow. Same with not treating it and lets not use the word job how about responsibility. If I were a source I would think part of that is the responsibility to send out merits. Your idea might be a good one for trusted members, but there would certainly be attempts to buy sMerits to send to alt accounts, friends, and who knows what. However, Theymos sent me a PM recently (after he changed my username) in which he said he had no plans to increase any merit source's monthly sMerit allocation--so I'm guessing he thinks there are already enough merits circulating and won't go for it. Just a hunch.
and Wouldn't that create a mess? Some account farmers would buy a few lots and then distribute them among their accounts to build up their accounts faster. These days there are a lot of signature campaigns around & I guess this would be a fantastic business idea for them LOL. Spammers would be everywhere; it would be hard to identify them sometimes as they would have so many earned merits.
That is why I said: Would have to be handled on a case by case basis, since you don't want to be selling merit to someone who might abuse it.
You could get away with it once but you would wind up burning a good account that Theymos thought was worthy of being able to buy merit and also it would be easy to see which accounts were sent to and those could be tagged too. Admin have confirmed that forum has sufficient funds to keep the forum running normally, they are no longer expecting donations and recently they are also not auctioning factoid slots. So I don't know what compelled the forum or the admin to agree to sell sMerit to its members. You should be able to easily earn lots of sMerit for free without having to pay anything, we know that.
Because I tend to give out a lot and although I do get a lot remember you need 2 received for 1 to send so my supply does dry up now and then. If it was a 1 to 1 or 1.5 to 1 it might be a different story. Or I might have given more to some posts so would have wound up in the same situation anyway. Since a few people did send some merits (thank you) I will keep them flowing. And now that the report posts that need merit post is back in my brain I will add to it as needed. -Dave |
|
|
|
I can see that you are a good poster, applying for a merit source would be good (but theymos is not even making anyone a merit source for now).
To me being a merit source would probably make me feel like I have to go out and send merits. More like an obligation. If I paid for them then it's more like they are mine I can be as free or as stingy with them as I like. Just my view. Knew yes, remembered no.... :-) -Dave |

Just went to merit a bunch of posts and ran out before I finished. Eliminating the become a merit source option, how about something like a copper membership so you can post images, a way to buy some merits from the source.
Would have to be handled on a case by case basis, since you don't want to be selling merit to someone who might abuse it. But, a couple of bucks for 50 or so merit might not be the worst deal.
Or I just start making notes and when I get some I send some. Never thought about it until now.
EDIT: This is not a beg for merit since something like that would only work once (now) but a more in general thing. I get some now but run out again in 7 months and wind up in the same situation. But throw a couple of dollars into the bitcointalk treasury and get some would be a workable thing.

Or mine at a pps+ pool where you know what they will pay in advance.
Agreed, and that's what I do but it's more a theoretical discussion about what can be done not what really is going on out there. I would be more worried at this point about small PPLNS pools going away and all that time and hash being wasted then anything else. And the fact that so many pools still do not use dnssec [ https://www.icann.org/resources/pages/dnssec-what-is-it-why-important-2019-03-05-en ] for their domains means that a crafty enough person can just re-direct hash if they can poison the DNS resolver you use. -Dave |
