1161  Economy / Scam Accusations / Re: Relationship between Bitmine farm/Bitmain farm scam website and www.Coinpayments on: October 21, 2020, 02:04:29 PM
@stompix: I had no idear...
I used to have an account with them which i created ages ago to receive payments for a service i had set up... And i remember being bugged by them to submit my KYC info after i'd been accepting payments for a long long time without any problems, so i decided to drop them... That's why I assumed that, because they require KYC info, they'd be more helpfull when one of their merchants scammed people... But i guess i was wrong.
1162  Economy / Scam Accusations / Re: Relationship between Bitmine farm/Bitmain farm scam website and www.Coinpayments on: October 21, 2020, 12:52:23 PM
Well, coinpayments is just a payment gateway... Sure, they'll be used by scammers, just like your FIAT bank can also be used by scammers.

Have you tried contacting coinpayments directly instead of reporting them? It's the scammer using coinpayments to receive funds, so it's the scammer that should be reported. IIRC, coinpayments requires KYC...

This being said, coinpayment's reputation wasn't always 100% perfect either.
1163  Economy / Currency exchange / Re: Best way to turn physical USD into bitcoin? on: October 21, 2020, 09:29:42 AM
Well, the cheapest and safest way is probably using a big exchange like binance or kraken. Chose an exchange that's licenced, old, big and trusted, follow the KYC procedure and withdraw as soon as the exchange is completed. The drawback is that these exchanges usually require you to go trough a full KYC procedure, witch can take a while... Some exchanges have turned scam in the past, but if you pick a big, licenced one and you only keep your funds on the exchange for the time you need to make the exchange and withdraw, your risk is limited. Oh, pick a random password, look out for phishing and enable 2FA if possible...

If you want BTC fast, an ATM is indeed a good alternative, altough a bit more pricey, and the worldwide ATM coverage is not that good (there might not be an ATM in your vicinity)

An other option would be a P2P trade, for example trough localbitcoins, but beware of scammers!

I'm a band new. If I want to lose merit very quickly, what are the things I should focus on first, and what should I avoid? Is there anyone That can help me get merit. Also tell me more about what I should stay away from? So that I do not become a ban.

This might sound a bit sarcastic, but the first thing you should do is use the search function and don't ask the same question that has been asked before dozens of times... It's one of the fasted ways of ending up on my ignorelist (and probably the ignorelist of many of the other longtime members). And if you want to earn some merits, the worst place you can be is on the ignorelist of people that have merits to spend...

Hi mocacinno,

- Bitcoind does appear to be running on the bitcoin user on the pi, can execute "lsof -i :8332" on the bitcoin user and get some feedback but on any other user the command does not return any information.
- I opened the bitcoin.conf file and was able to find the information you supplied in your post.

It seems like NBXplorer does not have a config file as entering that code results in an error stating the file can't be found, and one command led to a "Permission denied" error.

Not sure if I installed Dotnet or NBXplorer incorrectly. I would appreciate some further guidance in this. Thank you so much for all your help so far, you've been a big help. Looking forward to a reply, cheers.

Well, if i understand correctly, you're saying that nbxplorer did not have the necessary config file, and once you generated said file there was a "permission denied"-error...

I think it's a safe bet your problem is probably related to this config file... It's settings are necessary, it's not optional.

I start my nbxplorer as a service with following parameters:
/usr/bin/dotnet "/[path to nbxplorer]/NBXplorer/bin/Release/netcoreapp2.1/NBXplorer.dll" -c /[path to config]/.nbxplorer/Main/settings.config

So, you have to make sure the user/pass in settings.config match the ones in bitcoin.conf, you have to start nbxplorer with the -c parameter pointing to the settings.config AND you have to make sure there are no "permission denied" messages by changing the permissions or running as the correct user.

Have you tried rolling back your linux OS environment $ apt-get -s install $(apt-history rollback | tr '\n' ' ') i can't promise that it will work but it's worth a shot.

this command rolls back packages after an upgrade. This won't help the OP. He deleted the wrong line from a text file and re-saved it afterwards, rolling back upgraded packages won't fix this i'm afraid.

1169  Bitcoin / Wallet software / Re: Best Wallet Features on: October 16, 2020, 06:29:46 AM
When it comes to features:
  • it has to be a HD wallet: i don't want to make backups of my wallet file every couple of days
  • it has to be encrypted
  • native segwit
  • coin control features: i have to be able to pick the unspent outputs i want to use as an input
  • tx control features: i want to define the change address, or let the wallet derive a change address for me, i want full control over the fee (i want to set the exact amount of sat/vbyte and have the wallet make a couple of suggestions aswell), i want to be able to create unsigned transactions or sign unsigned transaction i constructed outside of the wallet
  • i want to be able to sign messages
  • the wallet has to be open source, signature has to be available
  • i have to be able to build the wallet on *nix

There are more features, but i probably wouldn't even want to use a wallet that doesn't offer above features as a bare minimum.

The UX, i don't care about... I use core from the command line, and electrum aswell... Sure, a gui is nice sometimes, and if you want to create a wallet that's newbie-friendly you really need one... But if you create a wallet for older users, i wouldn't worry about the ux all that much (at least, that's my personal feeling, i know a lot of old-timers that DO care about UI/UX)

Then will not someone be affected with that? Some people may use mixing service just for privacy, so that no one can trace how much BTC they have. Now, if they receive BTC originated from a scam, what would be the result if once they got caught. For example, if I use a mixing service for privacy and receive BTC which originated from hacking or such activities and later I have moved that fund to any exchange, wouldn't that result me tagging as the hacker?

But ARE you the hacker? If not, you should have nothing to worry about... The same with the serial number on the 50€ note in my pocket: if i go to a bank later today, and i deposit said banknote, but as soon as i hand it over to the teller he discovers the banknote was once stolen from an ATM, do you think i'll be in trouble? No, because i wasn't the one who stole it. Worst thing that'll happen is that the police might take my fingerprints and my picture so they can rule me out as a suspect. Or maybe they'll ask me if i remember where i got the 50€ note.
Not fun, but not terrible either.

I'll make a fictive case study here, i'm assuming a huge fee of 0.01 BTC/tx, irregardless of it's size (a dumb thing to do), i'm also assuming transactions 1 input + 1 output (no change, no multiple inputs):
1Victimaddress was funded with an unspent output of 1 BTC
A Phishing mail convinced him to spend his 1 BTC and fund address bc1PhisherAddress with 0.99 BTC
The Phisher mixes his funds by sending 0.98 BTC to the mixer's deposit address 1MixerAddress, he receives 0.96 BTC to his address 1CleanAddress
Some days later, you mix your 0.98 BTC and you get the unspent output that was funding 1MixerAddress as a return, so the mixer is funding 1Youraddress with 0.96 BTC.
You deposit these mixed funds to an exchange: 0.95 BTC to bc1ExchangeAddress

If we follow the uspent outputs and see wich addresses they fund, we see something like this:
1Victimaddress => bc1PhisherAddress => 1MixerAddress => 1Youraddress => bc1ExchangeAddress

Now, this is an over simplified example. You have multiple inputs, multiple outputs, the mixer does some internal reshuffeling (usually)... But even here: if the exchange sees this chain, how are they going to prove you are the owner of bc1PhisherAddress? They simply cannot because the funds passed trough 1MixerAddress. They can tell you those funds have a taint, sure, but they can never ever prove you are the phisher. Even if they would contact law enforcement, it wouldn't really matter, there simply isn't a 1:1 relationship, even in this over-simplified example.

Is the file still open in a gui editor? Most gui editors support Ctrl-Z (even on linux).
By any chance, is the filesystem btrfs or another filesystem that supports snapshots? In that case you can see if there's an older snapshot available?
By any chance, did you mount an NFS or something... Try looking for .snapshots aswell.
If you saved the text on a locally mounted cloud service like dropbox, they also allow you to rollback (it's NOT a good idear to save sensitive data on a dropbox volume!!!)
Any backups?

Depending on the editor you used, some editors save a copy of your file when editing, and remove the old version and rename the copy when saving. In this case, you could probably do a scan for deleted files using a tool like testdisk. The more data you've written to your disk after saving the wrong seed, the lower your chances of recovering are...

For ~1 BTC i'd even recommand shutting down your system (unless you still have the editor opened, look at the very first line) and cloning your disk with dd. This way you have a full clone of your disk to retry different salvage tools

Just for the record: i don't like your odds... Sorry to be the barer of bad news... But for ~$8k I wouldn't just give up, and I'd probably try to get my funds back...

According to chipmixer, it gives you some private keys that have no connection with the stolen funds. How exactly can the mixer's private keys be reported as illegal activity?
They give you private keys, which can be used to calculate public keys, which can be hashed.. These hashes (commonly known as addresses) can be funded with funds that can be linked with illegal activity. Just not with YOUR illegal activity... And that's the whole point of mixing...

--snip--
You can't compare bitcoin with fiat, because they're not the same thing. About the dollars you have in your pocket, yes you can't know if they came through some drug dealing. And the reason is that there is no ledger. On bitcoin, though, you can see if a hacker moved bitcoins from the time he stole them.
Sure you can... Banknotes have serial numbers...
It's perfectly possible for governement instances to see if a certain banknote was stolen from a bank... Or they can do trace tests for cocaine...
The point is: it's money... It shouldn't matter if it can be linked to illegal activity, as long as said illegal activity wasn't commited by the person whose currently in possession of the banknote in question. Nobody is going to convict you because you got a 5€ that was stolen by somebody else a long time ago as change when you bought a magazine.
1174  Bitcoin / Bitcoin Discussion / Re: Why do mixing companies want stolen bitcoins? on: October 15, 2020, 11:59:11 AM
Most of them send bitcoins they receive back to their next clients sooner or later..
Mixing is basically breaking the link between 2 wallets, it does not mean that the funds you receive as an output from the mixer cannot be coupled to any illegal activity... And that shouldn't be a problem either: can you prove that any fiat money in your wallet was never stolen or used to buy illegal narcotics?
1175  Economy / Service Discussion / Re: Does Coinb.in support SegWit addresses that begin with bc1? on: October 15, 2020, 11:18:20 AM
I know coinb.in uses javascript library's that run completely from your local machine, these library's use api's to query for unspent outputs funding a certain address.

Maybe there's a timeout from these api calls from your local machine? Could be the api provider, your isp or your computer/laptop/cellphone.

You can try to look at the console when you try to create a transaction?

You could also visit https://coinb.in/#settings => Unspent outputs and select a different provider and see if that fixes your issue...
1176  Economy / Service Discussion / Re: Does Coinb.in support SegWit addresses that begin with bc1? on: October 15, 2020, 09:38:15 AM
I took a random bech32 address by following a transaction i once made untill i found a funded bech32 address (the address is not mine)

I entered said address on coinb.in, and the unspent output funding said address was succesfully detected

Since you're running a hidden service, i can't try to connect to your node as a test... The main thing i wanted to say is that Christian Decker is usually really fast and friendly when you bring such issues to his attention. He has always helped me whenever I had some issues/found some "bugs".
However, he doesn't monitor bitcointalk that closely. Bitcointalk is a great place to ask for assistance, but in c-lightning's case, posting your issue here might lead to a serious delay in support time...

Try opening an issue on github, and you'll probably get help much faster:

Show me shops where i can spend crypto ...

crypto is useless...

type "buy with bitcoin" on google search and you will not find any major retailer using bitcoin or other cryptos

So what's the point of crypto if i can't use it to buy stuff ?

overstock
microsoft
newegg
namecheap
fasttech
caseking
kfc
wikipedia
AT&T
burger king
subway
dell
twitch
norwegian air
starbucks
etsy
gyft
nordvpn
...

either accept btc, have accepted btc in the past or some of their filials or country branches accept btc. There are literally thousands more... Both online and offline. These are just the ones i had in my bookmarks...

But if you feel crypto is useless, it's perfectly fine... Just sell any crypto assets you hold, store the FIAT in your bank account and walk away...

  • electrum can be run on testnet
  • wasabi can be run on testnet
  • bitcoin core can be run on testnet
  • a local copy of coinb.in can be run on testnet
  • armory can be run on testnet
  • btcd can be run on testnet
  • knots can be run on testnet
  • a local copy of bitaddress.org can be run on testnet

Take your pick Smiley
I guess the wallet you pick depends on the tutorial you want to give... Electrum is SPV and has a lot of coin controll options, wasabi has that built in privacy (including a coinjoin gui), core has even more features than electrum and it's a full node, coinb.in has an easy gui to learn the basics of tx creation, armory is built on top of bitcoind, btcd and knots have a little bit different feature set, bitaddress.org teaches about the many representation ways of keys,...
