Most mobile wallets allow you to paste in an address to send and add a receiving address to your clipboard so you can send it to someone the access itself is not that big a deal. With that I just played with a few wallets on my phone and most of them just took things from the clipboard without asking. So it appears to just be 'the way it's done'
Out of all the things that go on with crypto, things like this are some of the least of my concerns.
And, I know I have said this before, but I'll put it out there again.
YOUR PHONE IS NOT SECURE. DO NOT KEEP REAL AMOUNTS OF CRYPTO ON IT. YOUR PHONE SHOULD BE TREATED AS A HOT WALLET. ONLY STORE WHAT YOU CAN AFFORD TO LOOSE ON IT.

Is reproducible does not mean it is open source or the site is not correct about it. Reproducibility is one segment of open-source code. It's one of the conditions to be considered open-source, but not the only one. In an open-source world, you would be able to take any such code, modify it, better it, change it, put it in your product, and sell that product. If someone finds what you did useful, they could take your code and do the same, or just copy it in its entirety with no or minor changes. Coldcard doesn't allow anyone to use their codebase in the products they will later sell. But the funny part is that they built their own hardware wallets on open-source code written by others. I use a ColdCard but am thinking of moving to something else.
They seem to be dropping support for older HW and I really don't like the attitude of 'just buy a new one' How many updates are really needed in an airgapped wallet like the Coldcard? It only supports Bitcoin and is a simple signing device of transactions that are later exported and broadcasted elsewhere. Are your devices not working as they should for some reason that would warrant a fix in the form of an update? The old ones work BUT there have been some issues found that have not been fixed. And there have been some things added that could be added to the Mk 1/2 that just have not been. How long till they do the same with the 3. I understand the fact that your can't fix old HW bugs and that the older hardware can't run the newer code. But, and I know this makes me look cheap, if you bought a Mk1 and a Mk2 and a Mk3 give me some kind of loyalty discount. I know they remove all client info after X days, but there are ways to get around this if you really care enough. I know a lot of other makers do the same, and that means they will not get my money either. On the other side keystone spun off from the parent company and still managed to give old users of someone else's wallet a HEFTY discount on their items. ...Sure, some of them are discontinued because of big security flaws, that is much better than ledger creating graveyard for fashion purposes....
And this is it right there. There are known flaws, fine I don't expect a Mk4 for free to replace my Mk2. Just give me something. -Dave |

There is an interesting experiment that someone like BlackHatCoiner and possibly o_e_l_e_o could partake in. The dice that you linked to aren't available anymore, but if they could get an equal set, it would be fun to see how much entropy you could generate despite their bias towards rolling sixes. I see them as available here, are you US based? The biggest issue is HOW loaded they are. Are you going to roll 20% more sixes or 50% more 90% more? I would think that if you didn't know they were loaded after a few rolls it would be obvious. But the question would be how many till you go hmmmmm something is wrong here. -Dave |

Slightly OT, but something that was said to me years ago that stuck. All 6 sided casino dice are biased over hundreds of thousands of rolls. They are man made and will show it given time. But in the short term of hours that they are actually on the table it does not matter. If the dice here that @Pmalek are not used for anything else and came from an unknown source then it will never matter because there is still enough randomness in them. Now, loaded dice: https://www.amazon.com/Character-Builder-Loaded-Koplow-Games/dp/B001N1JIU8 that is a different thing. -Dave |

The Mk1 and Mk2 are no longer getting updates and the Mk3 is barley getting any.
So I had a 1 and then a 2 and now a 3. Sorry, you are not getting my money for a 4 or anything else. When it dies I'll move to something else.
Not saying that it would be better, but not even giving a you bought a bunch over the years here is a nice deal on a new one discount, just irks me.

More or less you are going to have to build something like this: https://litesoundbox.com/products/litesound-box-for-antminer-s19Probably a bit of trial and error to figure out what works for your situation. Keep in mind unless your power costs are less then $0.07/kw you are going to be mining at a loss. As for remote monitoring and control, just get some form of remote software for a PC on the same network and do it that way. If you have a lot of miners there are better solutions, but for 1 it's not really worth it. IMO -Dave |

Gemini seems to have a lawsuit against them as you have mentioned, you don't want to wait and see what the outcome of that would be. Withdraw your funds and use another platform. If you're from the U.S as I think you are, try Coinbase.
But Gemini was already in turmoil before that, when it's Gemini Earn program collapsed (because of Genesis et al, we all know the story by this point), their customers were burned, and nobody knows if the Winklevoss twins are pumping money inside the exchange to save it. Also, to those of you suggesting Binance.US as an alternative - it's not much better from a legal point of view.  Actually with a little digging you can probably find out who, if anyone is putting money in. They are regulated by the NYSDFS and have to obey their capital reserve requirements. And since they are in NY and not some 3rd world country where you can just pay someone to say that funds are there it's probably buried in some document someplace when discussing their capital reserves and where the money came from. I have said it before and I'll say it again, NY is an overly regulated state. But, with a lot of the finance things it really does help since they have proven time and time again they will kick out banks / financial institutions / etc. who don't play by their rules. -Dave |

Where are you in the world? Not every exchange operates in every country.
NOT YOUR KEYS NOT YOUR COINS
NO MATTER WHICH EXCHNAGE YOU USE
Don't leave your BTC on an exchange, deposit -> trade -> move coins to your own wallet.

....Core isn't designed for it, but in past i've seen people have hundred to million address on their wallet.dat file for their services.
Dave bangs head on desk. Why would anyone use a personal desktop client for running a commercial service? And even worse, one that is single-threaded for a lot of things. Ugh. Yes, I have done it, but usually within a bubble and with everyone knowing what was involved. -Dave |

I am not sure if someone would be smart enough to do something like a Bond when they have small amount of money. Sure if you have like 50 billion to handle and you do not have anything to invest at that moment and 45 billion of your money is invested and yet 5 billion is doing nothing, then yeah you get that and it is a smart move. But, for people like us? Bonds mean nothing, in most cases it is even worse than the bank rates, so why would you want something that is even worse than the bank rates?
I would say it would make more sense to just buy bitcoin until first billion, which covers 99.99% of the world already, after your first billion in bitcoin, then you may start to consider something else, like gold maybe, still not Bonds, they are just horrible.
Bond isn't easy to invest in if I recall, don't they only sell it or allow citizens to invest in it during wartime? Iirc aren't they called war bonds or there are other types of government bonds out there that you can invest in even during times of peace? What I'm getting from this post is that you're probably going to need a lot of money to invest in bonds right? Also why are bonds a horrible investment? I'm curious about this one. Depends on where you are in the world. US is simple, straight from the government: https://treasurydirect.gov/savings-bonds/buy-a-bond/The question comes down to, is are they worth it? For a safe stable income yes. But you are never going to get rich with them if you go for safe ones. Much like anything else. You might get lucky with a 10% APR yield bond. Or that countries economy might implode. -Dave |

So in theory if someone buys BTC through P2P and stores it in their non custodial or cold wallet, an agent of the United Kingdom law could simply knock on the buyer's door and demand to have full access to such wallet because some satoshis are suspected to be of an illegal procedence? Crazy if that is the case, because one thing is to seize a Binance or Coinbase account because it being used illegally, but a completely different thing is to ask some citizen to hand over their Ledger or Trezor because that person alledgely bought a handful of bucks which had interactions with a labeled addresses or addresses being recorded in a black list ...  In most parts of the world yes. Since they consider BTC to be property. If you on craigslist and buy a car that turns out to be 1) Stolen 2) Used in a crime 3) Belonging to someone who used funds that were obtained through non legal ways They have the right to take the car for #s 1 and 2 it's been clear cut case law for decades. #3 is a bit more difficult and courts have ruled both ways on the subject. If someone who looks like this shows up and sells you a lambo for cash cheap you are going to have a bit of explaining to do:  Vs someone who looks like this selling you a Toyota:  -Dave |

Simple response:  Complicated one Normally it should be seen as a paid advertisement, but what happens when there is bias involved? We can take for example a very long-running campaign I was a member and did not make any demands on where we post or quota post or use bumping power yet a lot of the members including myself when finding a topic where someone was asking for advice on mixing coins we would, not surprisingly, recommend the above not to be mentioned again service which after 6 years it ended as we all know, Was that post which recommended the service personal endorsement, yup, it was! Would one person carrying a competitor sig have made the same? No, let's not kid ourselves! Would we have recommended another one and not CM? Again, let's be serious! How many users carrying a sportsbet sig would say in a topic, hey!!, roobet has better odds, 2.5 instead of 2.25 on this event!  I would. When wearing the CM signature and even now wearing a different mixer sig I have pointed out that there are more private ways of mixing BTC then using a centralized service. Perhaps not as quick and easy but very doable. Years ago when I was wearing a Roo signature I posted in a now deleted thread that there were better bonus options for someone. (turned out to be a scammer who left but that's not the point here) -Dave |

What will stop the UK authorities from knocking onto the door of the business and seize those satoshis from the legitimate business owner ?
It is an scenario which could easily happen, because someone who is managing a business may commit the mistake of reusing addresses or using an address from an exchange, from there it would be just matter of time for police to get their name and address.
Hopefully nothing similar to that will ever happen .
Nothing. Same as if someone used counterfeited cash. You as the store owner loose. Buy a car that turns out later to be stolen because the person selling it to you forged the paperwork, you loose. And so on. This bill just defines crypto as an asset that can be taken as opposed to it being something that perhaps could be argued in the courts. -Dave |

You are renting space nothing more. If I had a AirBnB and you rented a room it's the same thing. You are just renting space that I have.
Personally I have never seen something that someone had in their signature (here are other boards) and thought that they endorsed it at all. Just generating some money from space they had.

I develop a wallet that communicates with Core via RPC. These things will not work because it would not be sure.
WHY? RPC is slow and not really designed for it. Core is really not designed for it either. Think about how long it takes when you have to rescan the blockchain for something. And as you discovered, it's designed for single user desktop use more or less in terms of security. And if someone has access to the PC and can get to the bitcoin.conf file, you already have other security issues going on. -Dave |

As far as SHA256 performance on CPU is concerned, there are special instructions available on most CPUs for accelerating the computation of SHA256 hashes. These are available per-thread, so the performance you get from using some generic SHA-256 function is going to be slower than a specialized function that makes use of these opcodes. Having said that, someone made a performance benchmark to check how fast calculating SHA256 your CPU is, inside the browser: https://www.measurethat.net/Benchmarks/Show/1246/0/sha256Not even tl;dr, just dr but isn't that going to only be able to use 1 core of a CPU? Usually most browsers will limit that. But no matter what running it in a browser although simple, will never give good results due to overhead. -Dave |

They are still here. Am I asking too much? I figured they would have moved by now.
With the loaded XMR being worth more than $75 between the pair that are loaded I figure someone would have bought them.
Been concentrating on moving out more of the car stuff over the summer, so I have not been pushing the collectables but would have believed that someone would have taken then my now.
-Dave
I don't think it's too much. I just think more people are hodling right now since the price seems to be jumping and btc consolidation starts to grow a bit early... I'd take the loaded ones, but not sure if you are willing to split them. I already have a few non-loaded, so it feels counter-productive to me atm  How about $200 and you take the non-loaded one too. Just cleaning up and don't want to have just the one sitting around. 3 do not take up any more space then 1. -Dave |

Fan in the case sucks. I think it's #3 or #4 I had to replace so many of them. m.2 SATA only will not take an m.2 NVMe No SD card. No Drive. No power supply. No support. US shipping only. Payment address: bc1qdufcfvlqtuhed84qrs4lfrhfla2ryw6jzljezu If you have any questions ask.    -Dave |
