FOMO la superlativ. Sau cum sa faci speedy pump and dump.
Poti sa zici de slippage sau ce vrei tu. Cand omul e lovit in cap de FOMO, logica nu mai conteaza.


1. Nici macar nu stiam de tokenul asta.
2. Am experienta 0.0000001% la DEX, deci oricum nu m-as fi avantat.
3. Pe exchange centralizat as fi stiut ce sa fac sa nu iau teapa, daca ar fi fost cazul, dar nu a fost cazul. Daca era cazul, cred ca m-as fi enervat pt timpul pierdut si nu as fi cumparat.


Chestia nu e noua, s-a mai intamplat la listari in trecut, dar nu la asa valoare.
Marketing bun, asteptari mari, FOMO cat casa, deci s-au dat cu capul de "pomul laudat", CSF? NCSF!

1. A lot of patience and (re)tries until  - with plenty of luck - the 3rd part or whatever company takes care of KYC documents is reached and ask for a human check those documents.
2. Declare some of those documents lost, ask for renewal (for a fee), have a picture with his current look. Do KYC.
3. Switch to a different service until - with plenty of luck - a smart one is found or one that doesn't check both documents and current live image.

I've noticed (from the bpip extension) that this user is now banned.
I don't know if it changes anything, still I think that MJ should be aware.

1. For something like this to happen, I expect that we may need Bitcoin price fluctuate much less.
2. Don't forget that as long as the main currency of a country is fiat, the shop will have the prices primarily in the country's fiat and then converted to all other currencies.

So no, unfortunately I don't expect the prices be shown primarily in bitcoin. Not everywhere.
For all the countries give up their tools for inflation (i.e. stealing money) we need a powerful change. Maybe even a radical change in the way some people end up taking decisions for the countries.

I've made some sort of test for Bitcoin with AirGap. The point was to try it out with a different "client" than AirGap provides.
Long story short, at least for Bitcoin alone, Electrum (for Android) + Electrum can be another pretty good solution.
For some it may be obvious, still, it may worth a spot in your list if AirGap is there. Or at least a side node.

You're partly right. The only phone I would have for this (if my HW would break today) would have (drums) Android 4.4.4. And I would have to see if I can flash an Android 5+ on it (which may or may not work).
But I expect many have older phones with Android 5+ on them gathering dust (while I keep my phones for 3+ years and then I give them to relatives for further use, I expect most keep them for 2 years then keep them in a drawer). And Google Play store shows that Electrum needs Android 5+. And that's old.
And you just don't need anything else on that phone, Electrum has its own scanner too.


Tails OS or similar USB sticks is seen as a good option for simple and effective cold storage. Still, if one forgets the network cable plugged in to the laptop, he may have surprises.
Or if you have a properly airgapped Windows laptop with cold storage and somebody else from your family plugs the network cable in,... same story.
I mean that there are always this kind of risks. In most cases for home brew cold storage the prerequisites are there.

If one cannot manage them I clearly recommend a proper hardware wallet.


As about the concept, I've been checking one of the topics with many "hardware wallets" (and similar devices). And I stumbled over this AirGap software and I thought "why not?". Just while for the cold wallet (or call it as you want) I know I have to be somewhat flexible, I do want to be able to pick the "client side", whether it's Electrum, Sparrow or something else. And my conclusion is that (for Bitcoin) Electrum+Electrum is better than AirGap solution, although it's not presented in that list.

But you're right, this was only a test. A proof of concept. For daily use - although this concept is fairly easy - I still recommend a proper hardware wallet, especially for newbies.

You are a complete newbie and the recovery of the money is still not risk free.

You may have issues with the account and final withdrawal may be denied.
You may have filled KYC and can ask support to reset your password and 2FA.
There are use cases you can steal the whole money of the lender if you want to.
Or you can play it all, just because, hey, it's free money.

The point is that the loan is not risk free for the lender and you don't provide any collateral.
I don't see why would anybody come with the "helping hand", really.

Imho you actually have better chance for negative feedback for attempting scam than getting help.

Umm... from what I understand there, this is your own wallet. You are Alice.
So I see that input 1 as the change from an older transaction of yours. (you'll understand this later).

You send money to Bob, but less than your total, hence you create one output (1) that'll be sent to Bob and one output (2), the change, back to yourself.
So this output 2 is money you have sent to yourself. So the wallet sees as money coming to you, or, as an input.
This input can be seen then as input 2. And you can make from it new transactions, like you've done with input 1. And maybe the starting part is clearer too.

All this is "somewhere in the middle" of the "life" of your coins, since at very start, the first input to your wallet clearly came from elsewhere (let's say from John).

This was a transaction involving change and that's why it may be a bit confusing.
If it's the first transaction from the "chain", then we'll have:

Well, this use case is meant for those who do know what they're doing and it's certainly not the best approach for safeguarding big funds. There's proper cold storage for that.
This was meant as an use case for some who really know what they're doing and it's meant as something relatively safe and much more convenient than a cold storage, probably for a short time, until a hardware wallet replacement is bought/delivered.

I expect such an user acknowledge that some risks may be involved. But let's not exaggerate them.
For example, after discussing that best is to never add an WiFi SSID at all, after implying that the device will never again have a SIM inserted and will also stay in Flight Mode, (also Bluetooth and NFC stopped), I think that your use case has very low chance to happen.
Of course that the fact the device is probably not encrypted is a risk. Of course that the data transfer (meaning tx) should not be done via USB or SD.
And of course that if one decides to do other tests that involve SIM or network/connectivity changes, he should first move away all his funds to a new wallet with a new seed.

From what I read, I'd understand the same thing as you from all this business.
And, more than that, after sending the 5$ back (imho that was kinda mistake, especially as you know that there's "no free lunch"), I could even consider negative feedback.

Indeed, I was worrying for nothing, it was much easier than I've expected. The AirGap Vault direction was counterproductive for me.
Indeed, it works with Electrum.
(And indeed, installing from SD sounds even better than setting up any WiFi.)

I had some small problem - I didn't find a way to made the Android Electrum on testnet -, but after finding out the right derivation path (m/44'/1'/0'), the Android didn't care it shows mainnet addresses, it signed the testnet tx gracefully.


Thank you all.

Indeed, I should have been explaining better, but the test was a bit odd... But it was meant to be a test
Here it is, as I remember it now:

I've generated a 12-word seed with IanColeman's to make it sure it's not an "electrum" seed.
I've imported it to Electrum, used it for testnet.
I've made one more watch only wallet (also on testnet) with the public key from previous step. This is meant to be the live wallet in my tests. I've sent some testnet coins there.
I've imported the 12 words seed into AirGap Vault.
In the live wallet made a transaction, shown the QR code and tried to get it with AirGap Vault to sign it. It has read the QR, but it said it's unrecognized data, hence I couldn't sign the tx.


Believe it or not, I didn't use Electrum on Android at all since (from what I've read) it doesn't support hardware wallet.
So (stupid me!) I didn't think at all on Electrum as solution. I'll give it a try later today. Thank you for the idea!


It's meant to be an old phone with no SIM,. So the only network may be the WiFi. I can make a temporary WiFi by Tethering from the in-use phone and never again use that SSID (it can be GUID). Bluetooth is turned off. NFC.. hm.. iirc it can be turned off.
Still, I understand your logic, and I will give it one more thought. The point was for a replacement for a Nano S at the moment it will no longer work, maybe until a new one is bought.
Of course it depends on how much funds one handles vs the expected risks.


Yep, this may be the actual technical description of my problem. Thanks for that.

I'll try with Electrum for Android, maybe the solution was easier than first expected.

In the solution you propose, I guess that he will have to get the output and parse it. Clearly possible and clearly inelegant too
On the other hand, in case he wants to do this (run a command line, get the output) for a website, I don't know whether that's possible at all (but I may be completely wrong too).

Of course, what I wrote was an idea OP can take into account or completely ignore. No biggie.

It may be much less painful for some (Linux?) C developer to convert that keysubtracter into a library and OP use/call that library from Python (if OP can do such calls).

I know that one can - under certain conditions - read a board that is ignored in his settings.
I've seen that one cannot merit posts in an ignored board. I don't know if that's the case about reporting, but that's where I'd start with.

So: was by chance the culprit post in topic on an ignored board?

After reading, discussing and thinking on the topics discussed about Ledger's hardware wallets', especially Why I wouldn't buy Ledger Nano S ever again? and Ledger Nano S Plus I came to the conclusion that the better option may be a DYI and a pretty cheap and safe solution could be using an old smartphone for the job, completely airgapped. Please correct me if I'm wrong.

The point would be that, with the right software installed on the phone, one can use its camera for reading QR from other smartphone or laptop, can display QR that can be read by other smartphone or laptops' camera...


I wanted to try out yesterday, shortly, AirGap vault with an Lectrum on laptop. On testnet.
It didn't work out and I don't know yet if the reason was that testnet is not supported by AirGap, or it's that AirGap vault works only with AirGap wallet.

Question 1:
Do you know what I am missing? Did you use this kind of setup and you know that it would actually work on mainnet with AirGap vault and Electrum?

Question 2:
Do you know of different cold storage app for Android? Can you please share?

Question 3:
Is there any similar solution I've missed? Some emulator under Android and installing the cold storage under that emulator? Then how I handle the camera/QR reader?

Question 4:
It's all wrong and I should abandon the idea?

Thank you.

Update: the setup works with Electrum on both sides - laptop and old phone.

I'm somewhat with LoyceV in this: the scams have happened very far in the past and probably before the trust system has become this important. Maybe I'm wrong, but I expect back those days one gave trust rating only if he had direct deal with the other person/account.
And most of the current active people don't know much about that, don't care that much about that... see it as "long gone". Not good, but this does happen. Politics and elections work on a similar principle, exactly because... as somebody famous said:



What I don't agree with LoyceV is about not "adding more to the pile". I've just added one more to the pile, with link to this topic.

Multumesc pentru notificare.
Desi premiul este frumos, nu e ceva care sa ma intereseze, asa ca las loc pentru altii.

I expect that some degree of corruption/protectionism does exist and if one has the proper "friends" his business is not harmed, even if it was declared illegal, as long as the business is not too big and doesn't draw too much attention.

Then, as others said, there may be some very small fish here and there which may costs more effort than the "benefit" of bringing them to "justice".

Back then, when these numbers first came out, I've told that the IPs can be spoofed and the "others" can be anything (and it's big).
That "Cambridge Bitcoin Electricity Consumption Index" has so much potential for being inaccurate it practically misleads everybody.

So indeed, I never believed China's hash rate dropped to 0.


On the other hand, it does show that the bulk of miners have moved or hide their tracks, hence there's no official mining in China, hence their political declarations should have low impact in bitcoin's price and evolution (unless they're unban it again, of course).

There are a lot of opinions in the other topic that may worth reading: https://bitcointalk.org/index.php?topic=5365501.0
