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 |

The owners of Celsius are well known and are subject to the jurisdiction of American courts. This is often not the case with other crypto scams. To my knowledge, the operators were not being paid exorbitant amounts of money. The business model of Celsius, if priced correctly, is something that should be profitable for its operators if run correctly. Celsius was in fact making loans.
A lot of people involved in financial scams are wall known.....and in jail in the US. So instead of stock fraud or bank fraud it's just crypto fraud. Once again from paragraph 12: Celsius also admitted at the 341 meeting that the company had never earned enough revenue to support the yields being paid to investors. This shows a high level of financial mismanagement and also suggests that at least at some points in time, yields to existing investors were probably being paid with the assets of new investors. If you are paying old people with money from new people you are a ponzi. They could have stopped payments, they could have cut them to the bone, but they kept paying out AND TAKING MORE IN. If you are making up numbers to put in spreadsheets to make your business look better then it is, you are scamming. https://www.youtube.com/watch?v=OWwzQyXAvXIDoes not matter the industry or what is being traded, crypto, cash, gold, it's all the same scam in the end. -Dave |

So they basically were able to get enough people to be willing to keep money on their platform for them to (hope to) be able to "earn" their way out of insolvency. Although this was going to be especially difficult considering your quote about Celsius not being profitable on an operational basis (I would presume Celcius management was trying to correct this).
Snark but...why would you think they were trying to correct it? What they had made the operators a lot of money. Going through the link that o_e_l_e_o posted it looked to be a scam / ponzi from almost the beginning. If I was running it and seeing all the exit scams that happened with no repercussions to the owner / operators I would keep running it that way. Difficult to withdraw, bonus for keeping funds in, odd rules, etc. It just screams non legitimate. -Dave |

Interesting, but as the saying goes, 'we don't know, what we don't know'
Accelerators may or may be part of it.
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.
Or, does pool "A" not want to deal with CPFP or other things for some odd reason so they ignore all those TX.
And so on.
But still a nice site you setup.

I started a discussion about this over 3 years ago, and back then it was still a re-hash of previous discussions: https://bitcointalk.org/index.php?topic=5154576I think it comes back to the people that care about it REALLY care about it. However, there are many more people that don't buy / sell /trade here so although it would be a good thing it will only matter to a limited number of users. Still really want it to happen, but after all these years, I just don't see it happening. -Dave |

Again it must be said: When building mining platforms one MUST follow local industrial wiring codes for distributing the power. If local codes are non-existent then follow international ones.. The pics above are just more proof of what WILL happen when ya 'just run a lot of wires' without knowing what you are doing...
It's not just without knowing what you are doing. It's not using industrial rated equipment, I had this happen to me early this year. https://bitcointalk.org/index.php?topic=5383773I'm sure there are 1000s and 1000s of people with 1000s of stories that we never see or hear about when something that was "good enough' went poof and destroyed a miner or 2. They might not even know what caused the issue, they just moved on. -Dave |

I'm with jackg:
Generate an xpub from the non custodial wallet of your choice.
Take those addresses and put them into a database and send them your customers as needed.
Do calls to a local block explorer to verify the payment and the amount.
This way you don't even have to have the private keys anywhere near anything in terms of the operation. Just a wallet sitting someplace that the coins go to.
It's probably a bit more programming and requires a bit more in HW (database server) but it is not that bad.

We all forgot to ask the other question, Menealo are you running any other things on the RPi or just core?
Eliminating the fact that it's under-powered and everything else could there be any other software grabbing the drive / IO something else causing the problem.
Still going to point to the device & power & drive but want to eliminate the fact that something else might be causing it.

Makes you wonder if there is a business model here of re-shipping crypto wallets. There already exist several companies which you can use to receive mail or packages and then forward to another address without opening, such as iPostal1, Traveling Mailbox, or Anytime Mailbox. It would be preferable to use a general company which forwards any package as opposed to one which only forwards hardware wallets, for the exact reason that if the forwarding company leaks user data, then if they only deal with hardware wallets then you are back at square one. 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. I know a lot of the mail forwarding places do keep records and have handed them over to the authorities if requested. The o_e_l_e_o re-ship service could get away with a lot more, and if you are ordering the device yourself you have 0 concern about someone shipping you a pound of meth that you then forwarded on... Taking it a step past that you could always keep a few of the more popular ones sitting around and then just ship from stock, but when the next model comes out you might be stuck with the old one. You would never get rich doing this, but beer money is good :-) -Dave |

Some subreddits are more heavy handed then others. Some blatantly favor some users / views more then others.
On the flip side you can always create your own subreddit and mod it the way you like, so long as it does not violate the overall rules of Reddit.
Personally, I think reddit does work well for some things but not others. There are a few crypo subreddits that I check in on now and then that ARE heavily modded and I like it that way. We may loose a valuable post, but on the flip side you are not digging through a ton of crap trying to find something. Take a look at the altcoin / token boards here to see what happens with only minimal modding.

Since another thread: https://bitcointalk.org/index.php?topic=5413066 just popped up with someone having issues trying to get core synced on a RPi3 with a slower spinning drive I figured that this thread was worth a bump with a few more comments. 1) If you are running on older HW you may get errors that are not really useful and although caused by the old HW do not directly point to it. In the post that I just referenced above the person was getting peers.dat errors. Could be unrelated could be due to the old hardware just not keeping up or having other issues. 2) The IBD is CPU / disk / RAM / hardware in general intensive. Some older hardware that works find surfing the web, watching videos, doing your taxes on, whatever. May show errors when running core. But, since everything else is fine you try to trace down what is causing the problem with the software when it really was just HW that could not keep up. 3) POWER. On SBC like the RPi or RockPi or any of the similar ones. I know its been discussed but you are powering the board and more then likely the drive too. You can't always get away with the cheapest wall adapter you can find. Sure there are more but just wanted to update here a bit and keep this thread alive. -Dave |
