Does it make sense to have mobile wallet + desktop wallet from same brand?

[Flexystar]

I got a very simple query to ask. I am recently switching from the Mycelium wallet because it has many issues in it's iOS version. It's not much friendly and frustrating to operate on the regular basis. The android version is good but I am not fan of it. Perhaps mycelium is in existence since 2012 but they have not progressed much.

Now I want to ask whether there are Wallets that are secure, synchable in between the desktop app and mobile app together?

For example if I am going to set up the wallet on desktop then I will have to enter the Private key there. In similar ways when I will set the wallet on my phone then also I will have to set the private key there.

Is it going to be issue to insert my private keys on two different devices?

I would personally not do that, I think the fewer devices the better (to reduce the risks), but yes, you can create an Electrum wallet on your desktop, and then use Electrum's seed on Bluewallet for example.

No issue, but know that your wallet will become more vulnerable as it is online on two devices. One can be better, but also depends on how secure you make your device to be. Avoid malware and store just little amount of coins on it.

For high amount of coins, go for cold wallet.

For online desktop, you can go for Electrum, Sparrow or Spectre. Or Bluewallet, for MacOS.

On mobile, you can go for Bluewallet for Android or iOS, or Electrum for Android. Know that mobile Electrum does not have fee customization but it has fee slider, but which is not that accurate for me.

Mycelium wallet? I can not recommend it as a bitcoin wallet. It is not even supporting replace-by-fee.

You can sync all your balance even with different brand because they are non custodial wallet.  Bluewallet and Electrum wallet is your best combo if you are an iOS since electrum is not available in there.

The only problem I encounter on iOS is the inaccurate transaction fee and very slow to update to recent transactions especially if you have multiple transactions made on different device with same private key.

No, as long as both device is secured.

[Charles-Tim]

The only problem I encounter on iOS is the inaccurate transaction fee and very slow to update to recent transactions especially if you have multiple transactions made on different device with same private key.

Bluewallet? It is like that also on Android. There are times you just have to close the app and open the app back. Also if you make transaction, you better check the mempool to customize the fee. The fee estimation is not that accurate, especially few weeks or months ago. Recently that mempool is showing 7 sat/vbyte, Bluewallet will estimated highest fee priority as 6 sat/vbyte which is causing the recent inaccurate few estimation.

The real question is why do you need to do this?

If you are going to spend bitcoin in person or make transactions on the go, then you want your hot wallet on your phone. Is there ever a time you are using your computer and you don't have your phone with you, which would require you to have the wallet duplicated on your computer? For most people the answer to that is no.

If you are not going to spend bitcoin in person or make transactions on the go, then you don't need your wallet on your phone.

Every additional piece of software you import the same seed phrase to increases the attack surface for that wallet. Similarly, every additional device you import the same seed phrase to increases the attack surface for that wallet. There is nothing stopping you duplicating the same wallet across multiple pieces of software on multiple device, but is the increased risk really worth it?

[LoyceMobile]

I wouldn't do it.

LoyceV give the long answer from desktop please.

[Flexystar]

Okay great I even got the solution of using desktop wallet (x brand) and synching it up with the another iOS app (y brand). So in the above case it seems to be combo of Electrum wallet and Bluewallet. I think I will give this a test run myself and see how it goes. I am doing this because I am mostly going to put it on laptop and use that very less. I will be having this over my phone because I would want to spend them on the go and I do not have viable option right now due to mycelium failure.

I understand the risk of having it on multiple devices but definitely we can have that much precautions while handling them and have best of both the world.

I think I will have to wait for @LoyceV until they get on their desktop and reply their long answer. I am excited about it as to why they wouldnt do it. Interesting.

According to my experience it should not be a problem but the best practice i follow is not to logging same wallet on two different device. Because in this way the spammers, hackers have two doorways to break, let's say before there were only one and you were safe too as that door was not breakable but when you created second door then that door might be breakable most of the time the hacks and spams i have seen are on desktop or laptops.

Because most of the people prefer to use cracked version of different apps on laptops (windows or IOS) + Most of the user even do not use official windows or any other OS instead they download them from websites (pirated ones).

The best practice if you wanted to log in any type of wallet on desktop is to not to use any crack website, or software on your device try not to click on any links etc. Try not to attach any usb or any other external device which might be compromised and then i think you are good to go. But still, these are just my experiences that i am sharing with you i hope you will find these helpful.

[o_e_l_e_o]

Then why put it on your laptop at all? All you are doing is doubling the attack surface, doubling the chance your wallet is hacked, and greatly increasing the chance you accidentally leak your seed phrase when importing it in to a new wallet.

If you are going to use your laptop very infrequently, then just keep the wallet on your phone. If you absolutely must interact with the wallet from both your phone and your laptop, then get a hardware wallet and pair it with both devices.

I understand the risk of having it on multiple devices but definitely we can have that much precautions while handling them and have best of both the world.

You can have the two wallets and probably not lose your funds, just the way you can have one hot wallet and not lose your funds, but it still doesn't mean that hot wallets are safe, because surely they are prone to hacking, and in your specific case, you are creating two channels that you can be attacked from without having a real purpose of doing it.

The best practice if you wanted to log in any type of wallet on desktop is to not to use any crack website, or software on your device try not to click on any links etc. Try not to attach any usb or any other external device which might be compromised and then i think you are good to go.

If it is your main wallet, run it on a totally airgapped device or use a hardware wallet, but if it is a hot wallet for spending on the go, then some of your advice here may help.

With the multiple wallets features that exist in Bluewallet, I don't think it will be a problem.
Bluewallet supports imports from several standard wallets including electrum and I have done it on the Android Bluewallet.¹

Everything depends on the user. If you feel doubt, there will be a problem, don't do it. Just use the Electrum Desktop to make it calmer even though the benefits of using a wallet in Mobile have ease when traveling.
Sometimes the need when traveling there is a possibility that it does not really require a lot of transactions.

Bluewallet supports Electrum wallet seed phrase importation, but know that any transaction made will not support replace-by-fee. Also this will happen if you import private key on Bluewallet. If you want your transaction to support replace-by-fee, use BIP39 seed phrase on Bluewalletnwhich is also the seed phrase that the wallet uses.

Will that matter though, especially since when mempoolrbf becomes the default option on full nodes (right now there is still a little pushback but it seems inevitable that it will be turned on by default at some point in the future), you will still be able to bump the transaction fee of Bluewallet transactions, just not in Bluewallet itself but in another wallet?

The full RBF has been on node settings many months before I posted this: Bitcoin open source wallets that support replace-by-fee (RBF)

There are many nodes that have not change their setting to support full RBF.

When it is time we do not need to discuss anymore about opt-in RBF, nearly all or transactions should have been supporting full RBF.

[o_e_l_e_o]

Pretty much. The stumbling block won't be if your transaction is or is not opted in to RBF, but whether your wallet software supports creating and broadcasting an RBF transaction.

There are already several major pools mining full RBF replacements, such as F2Pool and AntPool. And even although a lot of nodes have not enabled full RBF, it is still fairly easy to get a full RBF replacement broadcast through the network. Given that the average node makes 8 connections to peers, with only 25% of the network running full RBF then each node still has a 90% chance of connecting to at least one full RBF node.

You can take a look here to see all the full RBF replacements being mined: https://mempool.space/rbf#fullrbf

Air gapped device are the most best advice you have gave here. But sometimes the access to but them is restricted due to the legislation of some countries i hope you understand my words here. But if the OP here has the access to buy air gapped devices then these are the best options but i think his intentions are not to buy any instead of logging in on two different devices.

And for that i think best practice is not to login on two devices at the same time. Thanks for vouching me here. I really appreciate your concerns.

You don't buy airgapped 'devices', you create them yourself, by airgapped we mean a wallet that is totally disconnected from the internet and will never be connected to one; it is a DIY wallet. Let's say you download Electrum wallet on a completely airgapped device and verify your download, this wallet holds your keys that won't ever touch the internet, then on another online device you use the master public key of your airgapped wallet to create a watch-only version of the wallet, you use this to create and broadcast transactions that have been signed in your airgapped wallet, that's how it works. Though there are airgapped hardware wallets that you have to purchase, but that's not what my post was about.

I'm doing this for how many years while here and I never got a problem, when I'm away from home and can't access my PC, I used my mobile phone to access my Electrum wallet to transfer funds and convert to fiat without a problem.  But the most I like on PC version of the wallet has more features than the iOS wallet.  Of course, this is only intended for a hot wallet, not for a cold wallet.

It might be what you mean here is the hardware wallet, I never heard of someone selling an air-gapped wallet.

It's great that you're considering switching to a new wallet that better meets your needs. There are indeed several cryptocurrency wallets available that offer secure synchronization between desktop and mobile apps. These wallets often use a seed phrase (also known as a recovery phrase or mnemonic phrase) to securely generate private keys and addresses across different devices.

It doesn't offer "secure synchronization", if your wallet lets you access the privatekeys, you can actually access your bitcoins in any wallet regardless of the type of device with the default sync process (fetching data from the blockchain). Maybe you're talking about how to securely import the wallet to different devices, which one depends on how you do it.
