This is a misconception that Electrum on Andrion is vulnerable. Having fewer features on a Android version does not make it risky. You can download and use Electrum on your Android phone with full confidence. However, the desktop version of Electrum has not only more features but it is more user friendly and easy to use.

About the security of a Bitcoin wallet on android also depends on how the user is.
Nothing will be safe even a desktop electrum wallet if the user is not concerned about the security of their device and is not aware of some malware that will enter from various loopholes generated by the user.

If you are familiar with the desktop Electrum version, you may not be comfortable with the Android version. Personally, I have installed Electrum in my phone but never used it only because I do not like its interface.

Regarding the features of the Electrum wallet on Android, currently the android electrum wallet is also getting more features and a full overhaul of the user interface makes the Android electrum wallet more comfortable to use and more responsive.

The interface used to look more rigid, but for the Electrum 4.4.0 update version, it gives a new feel and a more dynamic look.
Very different from the previous appearance.

https://play.google.com/store/apps/details?id=org.electrum.electrum&hl=id&gl=US

#Release 4.4.0 (April 18, 2023)

Code:

* New Android app, using QML instead of Kivy
   - Using Qt 5.15.7, PyQt 5.15.9
   - This release still on python3.8
   - Feature parity with Kivy
   - Android Back button used throughout, for cancel/close/back
   - Note: two topbar menus; tap wallet name for wallet menu, tap
   network orb for application menu
   - Note: long-press Receive/Send for list of payment requests/invoices
* Qt GUI improvements
   - New onchain transaction creation flow, with configurable preview
   - Various options have been moved to toolbars, where their effect
   can be more directly observed.
* Privacy features:
   - lightning: support for option scid_alias.
   - Qt GUI: UTXO privacy analysis: this dialog displays all the
   wallet transactions that are either parent of a UTXO, or can be
   related to it through address reuse (Note that in the case of
   address reuse, it does not display children transactions.)
   - Coins tab: New menu that lets users easily spend a selection
   of UTXOs into a new channel, or into a submarine swap (Qt GUI).
* Internal:
   - Lightning invoices are regenerated everytime routing hints are
   deprecated due to liquidity changes.
   - Script descriptors are used internally to sign transactions.

Take note that any online device is prone to hacking.

Agreed, this is the exact answer in terms of using electrum. Your clarification in Electrum explaining that it is not Electrum itself that has the problem but rather the use of the wrong one that opens the way for hackers is dangerous because the device is open to risks.

Because of that, if the application of Electrum itself is dangerous on a mobile device, we probably shouldn't see it on the android phone to download it, but that's not the case, instead, it can be downloaded on our phone devices anytime.

1. Is there any way to generate bitcoin address offline without internet help?

Of course it can be done even without internet, I have done it several times with my friend. Then here in my local community there is a convenience store where you can buy Bitcoin and other merchants here as well.

Quote

2. Since Bitcoin launched is there any wallet that supports automatic Bitcoin gas fee editing right from your android or IOS machine?

What I know is that in Electrum, you can adjust the gas fee if you want it fast, just increase the fee or reduce it if you want cheap.

3. Do high gas fees mean faster bitcoin wallet transfers?

I don't disagree with you on some points, and it is more complicated to use compared to traditional fiat methods. Using PGP apps and verifying signatures isn't rocket science, and we shouldn't make it look like it is. You learn it after a 2 min video and then you know it.

I had no need to verify the digital signatures of anything either before I got into bitcoin. Now I know it and my life isn't any more difficult because I use a new piece of software and click a few buttons every couple of months. Basic IT literacy won't do you any harm in the 21st century, and it's expected that you know some things or know how to find the information you need.

Electrum doesn't operate the servers that displayed those messages and attempted to phish people. Individual users did. I can operate a legitimate server and you can operate a malicious one using the same software client. Those kind of messages can no longer be sent, but I am just saying.

My client broadcasts transactions normally > You configured yours with other motives.
If people who connected to malicious servers paid attention to the what they downloaded, installed, and from where, no money would be lost. If the signatures were verified, they would notice something was off.

Well initially the discussion was about the safety of the Android version vs the desktop one. But now I really wonder how Bitcoin could be widely adopted if people using it need to be IT professionals to avoid being scammed or robbed. How many people on earth know PGP, and know how to check a signature with it? The average Joe will never choose Bitcoin over fiat money if he can't even fully trust error messages from the wallet he is using. Bitcoin is already risky because it's a highly volatile asset, it doesn't need to be also risky when we are using it. Victims shouldn't always be blamed, softwares need to be adapted to users first, not the opposite.

So how would you call that?

This is more serious than a common phishing attack for me.

I would call it a vulnerability that was found and used by bad people (and they still use it today), in order to deceive Electrum users in a very vile way and convince them that the message they saw was legitimate. Certainly part of the responsibility lies with those who developed Electrum and who did not notice it in time, but also with every Electrum user who was not guided by the basics that say - download - verify - install.

As already said, there is no gas fee in bitcoin. The transaction in question took a long to be confirmed, because it used a low fee rate.

Some are apparently so deeply immersed in altcoins that they can't even call things by their right names...

You're wrong actually, I've never heard of a massive hack of the Android version while the desktop version has undergone an attack during several years causing many people to lose their funds because of it unfortunately.

Sad and avoidable? Yes. Was it a hack? No. Electrum allowed the people operating servers to send messages to those connected to them. That feature was abused to trick people into downloading fake software. You lost your coins if you used the fake software. Nothing happened to people that didn't use the fake apps. Hence, it's not a hack.

Imagine if theymos allowed Bitcointalk members to post random messages in a new chat feature or a notification bar at the top of the forum. If someone posts a link to an official Bitcointalk mobile app ver. 1.0, and 50 users download it and lose access to their Bitcointalk accounts, that's not a forum hack.

So how would you call that? A sad and avoidable but normal behavior for a software wallet? I disagree with you because here the messages were error messages displayed by Electrum software on the computer of the victims, after victims have broadcasted transactions, moreover the transactions were rejected by the servers. So we are not talking about random messages displayed on a random website or a forum here. We are talking about a weakness of a software exploited by malicious people. This is more serious than a common phishing attack for me.

To set the fee rate manually on trustwallet, you can tap on "Setting" button at top right corner of the screen before confirming your transaction details.

2. I am using Trust wallet and whatever transaction fee been asked of me when sending bitcoin is what I have to go with, though it's not very high but it feels suck not to edit yourself.

In addition to Electrum, Blue Wallet is also available to set the fee amount by pressing the costum button if the slow, medium, fast options are not desired by the user as shown in the image below.

Example of setting up a Bitcoin transfer using the Blue Wallet App

The process of using Trust Wallet on mobile to send Bitcoin is probably much easier as far as I'm concerned even though the fees are set automatically.
If it is just a transaction, Trust Wallet can be used. For storing Bitcoin, choose an open-source wallet to be more secure.

I believe most developers already give notifications/alerts about fake apps, whether it is on social media, in-app messages, forums, etc. Not to mention notifications like that is useless if a user is being attacked with phishing attacks, DNS hijack, or something similar. At least those that I'm aware of never wait until a user report that they get scammed to issue a notice saying that they won't ask for their private key, etc.

The suspicious apps don't need to ask for their private keys, it can easily expose who they're, the scam sites developers give victims addresses that belongs to them, they can easily increase the digits on the person's balance, but withdrawal will be impossible; pig butcher scam. So, what matters is that more people don't fall into the same mess. My suggestion is derived from the normal way of bursting scam, dropping a notification, indicating to users that a specific scam developer owns an app similar to theirs, which is used to take victim's money.

Quote from: joniboini on February 21, 2023, 10:31:16 AM

I think the main issue is how easy it is for fake apps to get listed on the play store, or how easy it is for scam ads to show on search results. A lot of users already complain about the lack of efficiency in reporting fake apps and ads, since scammers can easily list a new one under a different profile. There is no better way to solve this unless Google or Apple change the way they list new apps. I believe Google is more notorious for this though.

Google has tried to restrict strange apps from getting listed on their platform. Atleast I've heard some developers complaining about the hassle of uploading their app on the playstore. Yet that doesn't stop suspicious apps from finding their way into the app store. I'd say that some developers don't need to utilize the app store they can easily spam the links to their victims. Moreover Android phones warn users about the authenticity of an app without certificate, but they move ahead to download.

As it's difficult for the victims to differentiate the user interface, so an alert on the site would help save others from falling into such scam. Most importantly, the deed has been done.

However, some exchanges use offshore services to host their platform so that they won't be any traces whatsoever when things go wrong. While some would host their headquarters in a lawless country like you said, where they won't be persecuted.

I am certainly not an expert in administration and law so someone correct me if I am wrong. I think I read some time ago, that online services (like exchanges or casinos) need to have their servers physically in a certain location to be licensed and governed by regulators in that territory. The site and company itself can then operate in a completely different jurisdiction. I think that's how online gambling works on licensed casinos in North America where individual States and provinces have their own laws and regulatory frameworks.

I think the jurisdiction that issues the license to a casino would take care of the server location of that casino. For instance, the kahnawake gaming commission insists that the casino server would be hosted in the Mohawk territory. So, it can be concluded that the casino has a location for its server. The site can then operate in places like USA without facing any problem, but people are advised to be careful when using offshore casinos.

Indeed, its the problem most android app based wallets face, and the company cannot do anything to help the victims. Imagine if a wallet is hacked or an exchange they can easily be responsible for the refund.

With open-source software, you are responsible for the security of your money. The wallet developers aren't. If you get hacked, there is a bug, a vulnerability, or the software simply doesn't work as advertised, there is a clause where it says you can't hold the wallet creators responsible for any outcomes. Plus, they aren't for-profit companies generating money from your usage of their apps. There is no pool they can pay you damages from.

I am not sure what the law says that exchanges need to do in case of massive hacking incidents. But I have seen the mention of exchange hacking being called an "extraordinary circumstance" that the platform is not responsible for. It's also worth mentioning that centralized platforms prefer operating out of jurisdictions where they are more protected from prosecution than in the EU or the US.

I understand that nobody would be held responsible on open source, since different developers have an eye on the program source code trying to detect bugs and vulnerability, which tends to make it more secure and recommendable over closed source, isn't it beautiful to work with a wallet that has admins that can be held responsible if their platform malfunctions. True, not even a closed source wallet would care if their customer's wallet gets hacked due to the customer's personal mistake, but we are looking at a general mistake.

Yes, when you pay high fees it allows miners to pick your transaction and confirm it as a priority before the transaction from those with smaller fees.

Take note that miners prioritize the transactions based on their fee rate, not the absolute fee.
It's possible that a transaction paying lower fee has more chance of getting confirmed than a transaction paying higher fee.

Until today I really don't know why a lot of people come to the bitcoin world, but don't know the very basics of bitcoin wallet?. Actually, a bitcoin wallet is very simple than other (altcoin) wallets (trust wallets and Metamask).

If you begin with an electrum wallet, you will doesn't ask questions like a paper wallet, fee, etc. because everything in your question is in that wallet.

Take note that you can't always do this.
In the case the original transaction hasn't been flagged as RBF, nodes reject the second transaction even if it pays much higher fee.

In that case and if there's a change output to your own wallet in the unconfirmed slow low fee transaction you could use the CPFP trick and spend the unconfirmed change with such a high fee rate into your own wallet that the combined fee rate of parent and child transaction become more "interesting" for miners. (In most wallets you'd need to opt-in to spend unconfirmed coins.)
Of course this works only if there's an output in the slow transaction which you have control of (you have the private key to spend it).

I had to tell a friend about it, who recommended I should redo the transaction but with a higher fee rate, which I did and it didn't took up to 30mins to drop.

Take note that you can't always do this.
In the case the original transaction hasn't been flagged as RBF, nodes reject the second transaction even if it pays much higher fee.

1. Yes it's possible. Most of them do.
2. Yes, there are plenty of wallets that allow you to edit your fees. To mention a few: Electrum, Exodus, etc. Which wallet have you been using?
3. Correct. A lot of wallets allow you to choose "High, medium, and low" fees. You can go with that or If you want to fully customize the fees on your own, you should probably look into mempool.space so you don't end up overpaying.

3. Thanks, I asked because someone send me Bitcoin and I have to wait for like 15 hours before it finally gets approved in my wallet, I guess he used very low gas fee.

This takes my mind back to an experience in my early stage as a bitcoiners I had to send sum amount of BTC to someone and I decided to use a very low transaction fee rate and like over 8hours the BTC didn't dropped into the receiver wallet. I had to tell a friend about it, who recommended I should redo the transaction but with a higher fee rate, which I did and it didn't took up to 30mins to drop.
The only consequence in that experience was that I ended up incurring high (double) transaction fee rate which at first I was avoiding. An experience I wish never to reiterate.

1. I will like to know how to generate a bitcoin wallet offline without using a paper wallet generator.

You can install electrum and run it offline. (If you want your wallet to be completely secure, you should run electrum on an airgapped device.)

2. I am using Trust wallet and whatever transaction fee been asked of me when sending bitcoin is what I have to go with, though it's not very high but it feels suck not to edit yourself.

Since trustwallet is close-source, I wouldn't recommend anyone to use it. But it allows you to set the fee rate manually.
To set the fee rate on trustwallet, tap on "Setting" button at top right corner of the screen before confirming transaction details.

As already said, there is no gas fee in bitcoin. The transaction in question took a long to be confirmed, because it used a low fee rate.

1. As I said, most noncustodial (desktop or mobile) wallets allow that. Although I don't really think that Trustwallet is the best wallet choice for BTC, you should be able to create a wallet and generate your seed phrase even if you're not connected to the internet.
2. Trustwallet does allow you to edit your fees. See this guide[1].

Customize fee is for advanced users because a newbie may set a wrong fee amount that may lead to the transactions never getting confirm, but aside from that I don't see any big deal in doing and at most cases you are at liberty to set the amount you want to pay for fees.

While most wallets list this option as an "advanced" option, it's really not that complicated. Most decent wallets have nooby-friendly fee options like slow/med/fast options with their sats/b equivalent displayed, so it's easier for the user to choose a sats/b fee if they want to overpay significantly just to make sure the transaction gets confirmed in the next block.

What are the differences between the fee rate and the actual fee amount I was thinking both mean the same, please I will be glad if you can share more explanation for that?

The fee you pay for a transaction is equal to the fee rate (which is measured in sat/vbyte) multiplied by virtual size of your transaction (vbyte). So, the larger the transaction size, the more transaction fee you have to pay.
The virtual size of your transaction depends on the addresses type and number of inputs and outputs.

Yes, when you pay high fees it allows miners to pick your transaction and confirm it as a priority before the transaction from those with smaller fees.

Take note that miners prioritize the transactions based on their fee rate, not the absolute fee.
It's possible that a transaction paying lower fee has more chance of getting confirmed than a transaction paying higher fee.

Thanks man for the correction, all the while I thought the higher the fees the higher priority is given by the miners, until I read on this your comment that it doesn't entirely work that way, but I want to ask just a question I need more clarification on.

Yes, generating a Bitcoin address offline is possible and even recommended option. This method of creating a new wallet and generating addresses without the use of the internet enhances the security of your funds. As for transaction fees, there are numerous wallets that support automatic and manual fee adjustment for Bitcoin transactions. And, just a heads up, don't call it "gas fee". That's not a term typically used for Bitcoin network.

1. Is there any way to generate bitcoin address offline without the help of the internet ?

Yep. You can easily do this yourself.

You don’t even need to do this using wallet apps. Writing the code to do this for some of the older address formats is pretty easy and an interesting exercise to go through. I’ve found that very few wallets allow you to import the older addresses directly (for good reasons). Blue Wallet does actually though.

The way wallets do it nowadays with seed phrases is more involved, but you can even do that yourself without any wallet software using sites like this one:

Edit: Forgot to add. If you’re talking about wallet addresses that you’re going to use for actual transactions for funds you don’t want to lose then of course don’t use random sites or your own code.

Yes, I've read about this some time in the past, though I didn't really pay attention to understand most parts of the article, but I know that some service have made it possible to even send and receive bitcoin without internet connectivity.
You can google this to find out how.

2. Since Bitcoin launched is there any wallet that supports auto editing the gas fee of Bitcoin straight from your android or IOS machine?

Yes, you download and try Mycelium wallet, the app is available both on Android and iOS devices, the wallet offers the ability to adjust the amount of bitcoin you want to spend as a gas fee to have your transaction confirmed on the blockchain, but remember that the lower the fee you choose to pay, the longer your transactions stays without confirmation, and in some cases, you might end up not getting your transaction confirmed if the fee set is extremely low.

3. Does high gas fee means faster-sending speed on bitcoin wallet?

Yes, the higher the bitcoins you choose to spend as a gas fee for your transaction, the faster the transaction will get confirmed on the blockchain.

OP your question will take us abit back to discussing about types of wallet and their categories as well since i think this most important aspect is part of what you must have missed before going further into bitcoin, but remember that we have offline and online wallets, which if you had ever come across this while reading you may not have asked this question, so you can generate your wallet address offline, example is paper wallet, electrum on air gapped device etc.

2. Since Bitcoin launched is there any wallet that supports auto editing the gas fee of Bitcoin straight from your android or IOS machine?

Yes, a good example also is the electrum wallet, transaction fees are adjustable before a transaction is sent and after the transaction is made and not confirmed yet, you can customize the fee, to make it more easier, always check the mempool before making a transaction if fully busy or not.

3. Does high gas fee means faster-sending speed on bitcoin wallet?

Yes, it gives you higher priority over other unconfirmed transactions on the mempool by placing yours to the next to be confirmed transactions if you increase your transactions fee or if the mempool is not busy.

Bitcoiners don't like when the term "gas fee" is being applied to bitcoin because there is no gas. But yes, there are many mobile wallets that support manual fee adjustments, one of them is Electrum.

3. Does high gas fee means faster-sending speed on bitcoin wallet?

Higher fees may increase your chances of getting into the next block, it doesn't increase the chances of finding a new block. Your transaction paying a sufficient fee can be confirmed no faster than 10 minutes on average.

We have quite a lot of wallets that allow for such settings of fees, such as blockchain wallet, trust wallet and metamask and electrum are the popular ones I have used a few times.

1. With paper wallet generator or good non custodial wallet software, you can create your wallet and public receiving addresses offline. This is one part of creating air-gappped wallets.

2. Electrum is available for Android and iOS. You can edit transaction fee rates too with three options: ETA, Static or Mempool.

3. Fee rate is one part of your transaction fee that is by fee rate x transaction size. With same transaction size, if you increase fee rate, you are paying more transaction fee to miners. It boosts your transaction to tip of mempools and makes more quickly to be confirmed.

If you can't create an address offline, your not using a wallet.
There is no gas in Bitcoin. That term comes from a centralized premined shitcoin.

Additionally, since transactions on the bitcoin network aren't interacting with smart contacts, you can edit the fees to whatever you want (in a lot of cases, the lowest fee you can set will still get a confirmation - compared with eth which uses "gas" and can have smart contracts that fail if they're not executed fast enough).
