Honestly I've never had good luck running bitcoind and electrumx server on a RPi, not even version 4. I blame myself; I've never cared for Raspian, and always run them with the latest version of Ubuntu server. I've given away all my Raspberry Pis except for one version 4 that I use as a media server.
Currently I have a Dell SFF PC with an i5 processor, 16GB RAM, and a 1tb SSD on which I've installed Umbrel over Ubuntu Server 22.04.1. Umbrel is running Bitcoind, Electrs, LND, Mempool, and Tailscale. I also have Lightning Terminal and Ride the Lightning installed as well. I've had this set up running for about two weeks now without any issues.
Just did a test with a node in a box that I was going to re-image anyway. RPi4, 4GB, SSD. I tried to install everything in the app store and it would not. Crashed to the point that I could not even SSH into it. Did a power cycle and it came back but crashed again the same way. Could be that it's not actually crashing but taking so long to respond that both the web browser and SSH client timeout before it responds. So yeah, you can shoot yourself in the foot quite well with it. On the system you have. Assuming it's a 3rd gen i5 or better you could probably get away with installing everything. -Dave |

I think you need to make it clear what standard you use to list them as "the best". <snip> The' Best' all depends on the buyer - not some random person's thoughts... Most hardware guides here are pretty clear on that: 1st pick your criteria and choose from either speed, efficiency or, service life and go from there. There are no miners that are the top in all 3 areas. Personally I use service life as my #1 and that means any of Canaaan's Avalon miners. In normal use, according to your experience, which ones get less issues? Antimners or Canaan? Canaan are WAY more reliable then Bitmain. BUT, dollar for hash and power for hash they are a little less efficient. It really becomes tough call with a lot of variables, if you have inexpensive power that you think will stay that way for a long time, then the Canaan are probably a better buy. If you can't be sure of your power costs down the road then a bit cheaper machine that is a bit faster might serve you better since you stand a better chance of RoI and profit. With that being said, anything can happen, the 17 series from Bitmain was a disaster for a lot of people. I have one in a rack that was out of the 1st or 2nd batch running with no issues since it was dropped off. -Dave |

Nobody that I know who uses them for crypto processing has mentioned any issues, and I am the usually the 1st person they call when things like that don't work.
Just did 2 transactions through merchants that use BitPay and they went through with no problems, had to make them soon anyway so not a big deal to do the test.
With a quick look there is nothing on Twitter about it, and only the one report here and the one on reddit, and the merchant who replied. So it might be isolated, the reddit poster did not say where they were buying from so it could be a merchant cart issue.

Take a look here for some discussion: https://bitcointalk.org/index.php?topic=5411000.0In theory, with the cost of equipment, and the fact that miners do die / break so you can't be 100% you will even reach ROI never-mind generate a profit, it's a tough call. Mining is not just about generating BTC, more miners spread out all over help to keep the network running. But, small miners are really in a tough spot at the moment. Think about it before just jumping in. -Dave |

Only thing you need to buy is TTGO T-Display ESP32 device that cost less than $10, but it should work with all ESP32 devices like M5Stick, M5Stack Core2, ATOM Lite ESP32, etc.
LNbits can be used with Legend OnchainWallet extension, but other wallet applications can be used.
Where did you find the display so cheap, I have a few of them but they all cost me *a lot* more then $10. Other then getting the drivers installed when 1st flashing it any other issues? Looks cool, but as you said it's not the safest and the cheap ESP32 boards are fragile and the better ones are not cheap. -Dave |

in that timeframe i downloaded a single PDF file about some unrelated stuff
didnt really go on any dodgy websites or opened any e-mails
Kinda weird i dont know how i couldve been compromised
Unrelated bc it happened after the incident, but i downloaded the new electrum update from the original electrum.org
Sadly something could have been something sitting dormant for months before they decided to take your BTCIf your wallet was compromised a while ago they probably had a bot sitting there monitoring transactions, waiting for one above a certain amount to be sent to you. If that big transaction did not after a certain amount of time they just grab whatever comes in and move on. -Dave |

Was thinking about this some more. For a while I have wondered if the larger pools are running a standard stock node or something that is highly customized. And what other configurations they may have. When you see information like this it makes you think about what they have changed on the back end and why. And if it's better for the pool / miners. I saw this: According to this Poolin.com and Kucoin pool have highest lost average fees per block, and we know they are not at all the biggest pools.
And then thought, there has to be a reason, but since we know more or less how core operates unless they really tweaked their config are they even running it or something else. Thinking about what I said here: Along with agreements with exchanges, i.e.can exchange "A" always send out at a low fee since pool 'B" will always put it in their next block since they are getting BTC on the back end.
Is the possibility of a FU to certain people. i.e. we don't like centralized exchanges so all TX from known exchange addresses will be ignored. OR just avoiding US based ones like Coinbase / Gemini and so on or  Unless they come out and tell us we will never know, but it's an interesting thought experiment. -Dave |

I don't see any posts from him and he received 5 merits from three users in deleted posts. I am assuming he is already banned from the forum?
That's right, this user got a permaban for plagiarism, although I hesitated to report his posts because the source of this post was from another platform where the same content was published under the same name as on the forum. https://bpip.org/Profile?id=3502150Any reason you were hesitant to report? I know depending on my mood I can be a bit more or less forgiving at times, but people like that are in my view just asking to be reported. Looking through a couple of archived posts now and I don't see any reason that I would not have reported all of them. Just looking for other peoples views. I really think I should be reporting more, but a lot of people seem to be more tolerant then I am so I don't wind up reporting some things, because I see a bunch of replies so I think some people think it's worth discussing. -Dave |

Since it was a bit light on details we don't know exactly what they are going to be doing with OpenNode. But, at least here in the US a lot of government things are done by 3rd party people. It's just easier and quicker and usually cheaper for a lot of things.
Places like the DMV, that take credit cards use 3rd party processors. If they wanted to take BTC could they spin up their own nodes and come to an agreement with some exchange for getting it converted to fiat, yes. Would it be easier / quicker and probably cheaper to just get a payment processor to do it for them, also yes.
Till we know more of what they are doing I'll file this under a good thing.

Output: EXCEPTION: NSt10filesystem7__cxx1116filesystem_errorE
filesystem error: cannot create directories: Permission denied [/mnt/hdd/bitcoin/regtest/wallets]
bitcoin in AppInit()
Like someone mentioned in your other thread, there's a permission issue. Try to add -datadir=<full path to a folder> to your command to create Regtest's data directory somewhere else where you have the permission to write. Take note that the specified directory should be existing prior on using the command, also, the specified datadir= is the " bitcoin" datadir so instead there, a " regtest" folder will automatically be created inside it where the regtest files will be created. The OP mentioned that it's a raspiblitz setup, IIRC it runs bitcoind as it's own user so you will have to make sure that that user can write to that directory, not the user you SSH in as. I like the pre-done nodes like this a lot, but you are living in their world to a certain point so things that might be simple on a device you did yourself might require a little more tweaking on one of these. -Dave |

Some people just deserve a negative trust. It goes beyond trading. It comes back to the fact that they are actively hurting the community.
Scammers come and go, and we will never be able to catch and tag them all. But, they do tend to leave after the scam is done, or they have so much negative feedback and so many active flags that they can't scam easily anymore. People like this need to be called out each and every time they post until they leave. Ignore only works to a point, then you have to move to another method.
theymos / the mods don't want to be censors, and that is fine, we just have to keep up the pressure on the trolls because they won't ban them.

The issue with greenhouses is they tend to be humid, which is not good for miners. And during the hot summer months you need to get more heat and humidity out of the space.
Over the years there have been a lot of people with a lot of plans to do something with the waste heat.
Using liquid cooling is fine, but do you want to have heated flooring during the summer? If not you have to have a 2nd water path to move the heat someplace else.
Also, it adds complication. I have an air cooled miner I can put it anyplace where I can move enough air to keep it cool no though given to plumbing....

Beyond the security implications, there seems to be nobody asking for it. If there were people asking / talking about it more people would be writing them and we would be discussing them.
I would not really want to use one for real amounts of money, but for keeping small amounts, under $25 or so, it might not be the worst. If you are only using 1 PC and occasionally want to get something with BTC having a high risk, vulnerable hot wallet with that amount give or take could be handy. No going for the HW wallet, or anything else. Obviously everyone would have their own amount of BTC they would be willing to risk.

Beyond it not being possible to do without a lot of collusion and spending a fortune in money it's also a very large risk.
Much like the 'any 2 people can keep a secret so long as one of them is dead' to create a scenario where you get that much hashrate you would need a bunch of pool operators and some tech people who would do the actual programming. Someone is going to talk and then the hashrate to those pools is going drop like a rock.
There are a lot of theoretical ways that it could happen, but in reality it's never going to. There is too much long term profit to be lost.

Tried a couple of different countries with a VPN and got the same blocked message as everyone else.
I have them in my Google 2FA but I really don't remember what I had there or when the last time I used it was.
Makes you wonder how many accounts are out there like that, someone got some crap coin, traded it for BTC and left never to come back.

Do you have in your bitcoin.conf file? Also, since you are running raspiblitz I am not sure if there are any other changes needed. There should be none, but I don't know if there are any other custom config files that it added. I don't see any on my node but I have not tried regtest on it so I can't be 100% sure. -Dave |

Brings up an interesting question. Leonardo Da Vinci came up with the concept of the helicopter centuries before technology was able to build one.
Was he the father of the helicopter or just someone who was ahead of his time.
Satoshi created BTC, but the concept of digital money using different words and concepts was around for a long time before that. Is there a definitive 1st mention of digital money somewhere?

How powerful is the machine you are running it on? Could it be that it's taking a REALLY long time to process blocks and until there is a long amount of time between blocks it just can't keep up?
Same with bandwidth, blocks are only a couple of megs but if you are on a slow connection with another PC on the network streaming netflix & youtube....
The clock being off should not matter, unless it's REALLY off. I have seen some odd behavior when that happens.

I look it at closer to the fact that a single trusted user doing it as a side hustle that only deals with hardware wallets is more likely to get away with the 'I don't keep records' thing if something happens then a full service company. Yeah, that's a fair point. I guess you would then need to weigh up the pros and cons of not having your details shared with a hardware wallet manufacturer and all their third party buddies on one hand, versus inserting a third party in to the delivery chain and the theoretical risk of supply chain attacks. And even if you trust the third party not to attack your hardware wallet, do you also trust them to be as honest as they claim with your personal details and have a rock solid security set up? But I guess if you are like me, and are getting to that level of paranoia, then the best option is probably going to be to ignore hardware wallets altogether and use an airgapped computer instead. I look at it more as OP-Sec then paranoia. Going with the assumption (yeah I know assumption) that a trusted user here is a low risk source for supply chain attacks then it is IMO somewhat easy to be invisible. Disposable email -> new account -> contact shipper-> give info -> send BTC -> wait for delivery. It could be you contacting the shipper, it could be theymos, it could be anyone, does not matter they would just need a name and address to ship to. Taking about edge cases here, but still interesting to throw ideas around. -Dave |
