Is this good advice for those who can't afford a hardware wallet?

Using a Bitcoin Electrum wallet or other, disconnect from the internet before generating a new seed and never connecting to the internet again.

Until you are ready to sell everything in that wallet.

Is this practice similar to using a hardware wallet? This advice came from a man I know who said to have been keeping his BTC since 2013 in the same manner, he said the internet/online is the culprit or enemy of every crypto wallet.

If you want your electrum wallet to be completely secure, you should create it on an airgapped device.
This means that you should use a device which has been always offline and will never connect to the internet.

Remember, when you generate a new seed from disconnected PC, this disconnected PC doesn't mean it safe if you ever use this PC to connect with internet or you bought the used one.

You need to generate a new seed on fairly new PC or you've reinstall and cleaned the not secure PC.

When you need to send your coins, you don't have to spent it all.

Just create unsigned transaction in your offline PC and sign it in your online PC, read https://electrum.readthedocs.io/en/latest/coldstorage.html

Yes. This is a good advice. But, I don't know how people use their computer or mobile device without an internet connection. If you can afford to buy a laptop or a computer to use as a hardware wallet and never connect it to the internet, you should be able to buy a hardware wallet as well. Simply disconnecting and never connecting it to the internet is not enough.

You should not connect any device to it that has internet access, and you should not use any pen drive to transfer data. Because you never know if there is ransomware or not. A hardware wallet costs around $50 to $200 depending on the model and the company. You should take one if you are serious investor.

You are describing an air gapped wallet creation which is almost the same to hardware wallet assuming the device you use is an air gapped since you will not move your tokens after you create your wallet.

And yes this safe as hardware wallet. The only difference is you can’t transfer funds conveniently like the hardware wallet technology. I do this before to my old laptop but it’s hassle for me because I always want to transfer part of my funds so I just purchased a HW that only cost a couple of hundreds for safety and convenience of my asset.

That's one way to do it but you need to make sure you're creating the wallet on an air-gapped device running secure open-source software. Which, probably majority of the masses aren't capable of doing so they're better off just buying a cheap hardware wallet.

Also, the limitation of that is it's solely for hodling. If you want to use the bitcoin to pay for something, you're putting your funds at risk for connecting to the internet.

It's not.
You don't make your device air-gapped with disconnecting it from the internet, even if keep it offline and never connect to the internet in the future.


Take note that whether you want to spend the whole balance or part of it, you should make your transaction offline which means that you should create an unsinged transaction on an online device and sign it on an offline device. Otherwise, you would defeat the purpose of the cold storage.

No it's not.
I have seen to many people making mistakes with their imagined fake airgapped system, that I can recommend everyone to stay away from setup like this.
There are to many things that can go wrong, and people don't really understand how to keep everything offline and updated in the same time.
It's not that hard to get hardware wallet today, for example Satochip cards are lees that $25 with discount, Safepal is almost free, Jade and Trezor One are aroud $60, etc.
If you don't want buy anything, than using old smartphone would be acceptable with disabled all connections (airplane mode) and removed sim cards.

No.
You don't have to complicate things with hardware wallets, just make a transaction.
If there was no internet, there would be no bitcoin, so internet can't be the culprit or enemy of anything.

If you are into building your own cold storage then you should start educating yourself on a couple of topics like what "airgap" means (others already explained) and how to create one. The best and safest solution in my opinion is to dedicate a USB disk to a Linux OS (installed not live) and having your wallet in there.
Here is a very old topic with a step by step guide to create a DIY kind of cold storage: https://bitcointalk.org/index.php?topic=853288.0

If this is your first time with Linux, Bitcoin, etc. you can take all these steps and create a TestNet wallet with some TestNet coins which you can get from any faucet out there. This way you don't have to worry about losing money. Receive some coins then send them out to learn how things work.

As others have said, this kind of setup will fall under the category of air-gap PC and it should not be connected to the internet once you have set up everything. Although if I will have to choose between a hardware wallet vs a air gap pc, I will go with the hardware wallet.

And if the person that known have this kind of setup since 2013, then good for him. He could be very knowledgeable and knows how to protect hit Bitcoin with that kind of setup. The key here is that you know what you are doing if you chooses air gap setup.

You forgot a step.  Verifying the download before hand.  By skipping this step, it may not even matter any more whether you are connected to the Internet or not because you could be running a malicious version of Electrum.

Until you are ready to sell any thing, you could start learning how to spend and receive Bitcoin with no Internet connection.  Doing this is VERY easy and simple if you have a little practice on your hands.

I rather think the main culprit is our own.  We care too less until it becomes too late.  You can skip most of the attack vectors by simple extra steps.  The main issue here is the word 'extra', which many people run from.  Better add a few extra steps and be safe than be lazy and cry out loud later.

But hardware wallets are not too expensive, many wallets are quite cheap, such as the Trezor One hardware wallet, which costs less than 60 USD each. And I think if we are serious about our bitcoin investments and intend to keep them for many years, spending $60 to own a hardware wallet is not too expensive. But it's okay if we use Electrum wallet or any open source software, as long as we meet enough factors to be safe for it. You can use any wallet you like, but don't make the excuse that a hardware wallet is too expensive to own.

If you're investing much on bitcoin and you're yet complaining of the unaffordability of buying a single hardware wallet, then that means you're not giving the necessary attention to what can jeopardies your asset, even though electrum wallet is not a bad option once its on airgapped device.

It all depends , because if you're still using electrum wallet, its something different from hardware wallet because it does not have a physical showcase as how you could move, store , use and apply its uses on any of your interested device, however, there are alternatives as well to using a hardware wallet as you have given one example already, one can make use of a paper wallet too, or anything that has to do with a wallet types which falls under a cold storage.

Doesn't it look strange when a person can afford to invest in cryptocurrencies, but can't afford a hardware wallet for ~$100 (often even less)?

Why all this complexity and twisting, when it’s easier and safer with a hardware wallet?

One day there will come a time when you will have to connect to the Internet to sell crypto assets, and at this point a catch may await you with a compromised PC (infected with a malicious program).

Shouldn't we be careful about this?

Isn't the user himself the enemy of his wallet? By not recognizing hardware wallet, users make mistakes in storing crypto assets, leading to losses with cryptocurrencies. So far, nothing safer than hardware wallets has been created against online threats (taking into account that the hardware wallet is from a reliable manufacturer).

You are right that it would be better to use a hardware wallet, but it's not that you will have to connect to to the internet for spending your bitcoin. You can sign you transaction offline.
If you install your wallet on an airgapped device and do everything in the correct way, your wallet can be as safe as a hardware wallet.

As long as you can make sure the device isn't online as long as you don't need it, I think it's still safe to use an electrum wallet to store Bitcoin as long as you don't spend it.
Hardware wallets are also inexpensive to purchase if one has the desire to own one.
The safest way to use a Bitcoin wallet like Electrum can be followed by the method given by people here.
Regarding wallets storing Bitcoin, don't take it lightly if you don't want to regret it.

Having an offline wallet on an airgapped device is practically the best way to store your bitcoin for a long term which believe I that's the same measure the said person is talking about.

But one also needs the hardware wallets, there is absolutely no reason to justify that one has a thousand dollars investment in bitcoin and can not afford a hardware wallet, is that weird?.
For me what ever it takes to remain safe is the ideal goal, and a cold storage is what guarantees a better security.

No, the practice is not similar to using a hardware wallet. On hardware wallet you're putting your trust the wallet creator to create something genuine and safe for long term of your crypto and this is why open source hardware wallet is advise for public flaws checkup.
The practice you explained is called airgap wallet and it's secure if used a device that's not physical, or wireless connect to the internet and other computering devices.

Even without knowing all the complexities of wallets and computers, you can already think of hundred of ways that this could go wrong.

First of all a computer itself would have to be updated constantly so that its system functions well. Many devices tend to malfunction if not used for a long time so how do you expect to open your wallet if the device itself is not even functioning properly?

Just get an actual physical wallet and research of ways to store it the safest way possible.

Yes no doubt you have given a good advice. Your advice is reasonable and accurate.

But if you are a high level investor then you directly buy hardware wallet and deposit your BTC in that wallet. Only use that hardware wallet later when you are ready to sell.

On the other hand, caution should be taken for added security when using Electrum wallet. Create Electrum wallet using internet connection only once by electronic device i.e. computer, mobile or smartphone and it is better not to establish internet connection on that device before preparing to sell BTC. In this case, do not use any type of input device to protect yourself from harmful viruses like malware or ransomware.

In my personal opinion, it is better not to use Electrum wallet. In this case you should get used to using hardware wallet.

Really difficult to do but this is the way to go, no way that hackers or virtual crooks can get in when they can't connect to it other than a physical interaction to the device.

What you're doing OP is a good idea though, I'm sure that there's a way that you can do it much better, maybe follow what @hosseinimr93 advised, airgapped devices are basically impregnable.

There are huge differences between a hardware wallet and an air gapped PC.
To be honest, using a hardware wallet is much cheaper, easier, secure and convenient than to use an air gapped PC.
If you still want to go ahead with using an air gapped PC then you can go ahead with the process you mentioned.
Be sure to get the wallet from official source only and make sure it is open source.
Make sure that you are not connecting the device to internet or connecting any storage devices to the air gapped PC.

If I didn't have a hard wallet like me, who only used an electronic wallet in the few years I've been using it, I wouldn't have had any problems with this. really proven and tested,
as long as you always update it so that you are not prone to hackers.

Think about it: after 6 years, I can still use electrum up to the present time, which means it is really 100% completed, as long as it is correct and you know what you are doing with it.

What you are saying?
You don't need internet connection for creating your electrum wallet at all. Your keys are generated through some mathematical calculations locally on your own device.
You can also sign your transaction offline without any need to internet connection.

If your want your wallet to be cold storage, your keys should never touch the internet.

This is the best way to hold and to avoid another expense for a new hardware wallet, only if you have a spare computer.

Although i used electrum on a laptop where it is connected on internet but never had any lost or hacking issue since i entered this space. It's matter of good practice on how to use the device and use AV as precautions to avoid undetected malware on the device.

Old smart phones can be infected with malware even before you turn it to an airgapped device, i will say OP should rather stick to the hardware if they are serious about holding their coins securely.


Updating the wallet doesn’t stops you from attacks or hacks it is just as same as the old wallet just that bugs might have been fixed but external attack are still very much same.


This is totally wrong, you don’t need to set up a 2FA if you don’t want it. You can simply create a new standard wallet like the other wallets do except that electrum seeds are custom seeds. You can add pass phrases like other wallets too and also use multi sig if you prefer it. The 2FA just an extra option if you want. It is not compulsory to use it if you don’t want it.

Also Electrum is available for all softwares except IOS (iPhone smart phones). That means on mobile device it is available for Androids only but available for all softwares on laptop or computer. There is nothing different with electrum and other wallets.


Yes I agree with you that the way you treat your wallet is as important as the choice of wallet it self in securing its funds. But no matter the level security applied once a wallet is an hot wallet. There is the risk of it getting compromised. You can’t be sure or trust it because you haven’t experience it before. Also it is not all Malwares that an AV can dictate so relying on them too is risky to me

That would work in my opinion as long as it didn't connect to the internet and only use the wallet address to receive bitcoin and only connect when you want to sell. It's entirely up to you on what you should do and we are only giving you an idea on what you should do and shouldn't do. You can start creating a wallet on electrum which supports different devices like desktop and mobile devices and create a backup of the seed phrase which is used to access the wallet.

You don't need 2FA to login or access the wallet if you created a standard wallet which doesn't require you to complete 2FA. Electrum wallet can be used by newbies and you are right about electrum having 2FA but it's up to you if you use standard wallet which doesn't have 2FA or required 2FA or with 2FA wallet.

Op yes Electrum wallet is good for a reasonable amount of big to be hodle but if you are holding big or huge amount of bitcoin whether Electrum wallet is good for offline or not or is better for your to use hardware wallet which is more saver than the Electrum wallet of offline. If you have it in your device and the day you connect your device to the net and you were about checking your wallet that day then it must connect to the internet and one thing I discovered from Electrum wallet is that if you didn't connect it to the internet, you won't see the current balance if you transfer new coins to it unless you connect it to the internet before the present balance would show.
So the best way is to buy hardware wallet and just transfer the coins to it and let them stay there until you want to use them.

That's good advice mate, you can make an Air-Gapped wallet, using electrum and Electrum is the best choice to do it as it can generate your seed phrase, just disconnect the internet, open the wallet, create the wallet, a seed phrase will be provided. But I doubt how you will manage to get the address (receiving) to store funds in them.

Besides it, the guy who has been into crypto since 2013 and you are in the circle with him, dude I must say you should accept him as your mentor. As these people are OGz and if he still has the BTC from that time, then he is a pro OG as he has bear a hell lot of pressure. People like these are not easily found haha. This guide might help you (https://electrum.readthedocs.io/en/latest/coldstorage.html) -------Electrum air gapped device (https://bitcointalk.org/index.php?topic=5452981.0) Air-gapped wallets are best and the knowledge that a person gets while setting them up is also awesome. best of luck

We trust Electrum as a hardware wallet. If you can't afford to buy a hardware wallet, then you can use an Electrum wallet. But you need to secure your wallet seed safely. And the device you are using, the Electrum wallet, should not be compromised. The important thing is to secure your seed, and your device should be secured from the attack. Also, make sure you keep safe seeds in multiple places; in case one is lost, another will recover the wallet. But it is always best to get a hardware wallet. 

Well, electrum wallets I think have popularity and legitimacy. I didn't use this wallet, but I saw many users recommending and agreeing with you, so I think it is a good wallet to use. You just have to make sure that your wallet will be safe from anyone, and also the seed phrase you need to secure in order for you to access it anytime you want to. If you want a wallet that cannot be reached by the internet and is away from malicious intents or attempts, then use a device that you will not open or access the internet, but of course you need to secure that device, and it will add up for you to secure along with the seed phrase. Even a low-end device will do; it doesn't need to have high specs, just that it can handle an electronic wallet, you can also use that device as your OTP where all you OTP sim or email are in that device.

I guess that you are a little bit paranoid here.
Electrum is really secure. You can add additional words to the 12-word seed. You could create a multi-sig wallet on Electrum(multi-sig wallets are more secure than standard Electrum wallets), or you could simply add 2-factor authentication. Those 3 options can totally enhance the security of your Electrum wallet.
Are you really sure about "never connecting to the internet again"? You will have to connect to the internet, when you decide to sell your BTC. Do you plan to keep BTC forever in that wallet, without touching them ever again? This seems weird.

Well, you do not need Electrum to do that, because you can simply create a Paper wallet with a offline script and only import that Private key when you want to use it.  :D

I used Electrum for a while to collect some dust for things I did online and only accessed that wallet on the day when I shifted those coins to my hardware wallet. (Just make sure you store your pass phrase, when you create that wallet)

For you to have an amount of coins that you jealously securing against any malware attack through any internet connection then you should be capable of affording a hardware wallet without stress right? Because from what is established conventionally in the financial world is that people only create protection on something of great value to them.

Electrum wallet is one bitcoin wallet with a good security I can at any point in time recommend to bitcoin users, and if it's a small amount of coins then it's a great idea with what OP has proposed for those that can't yet afford a hardware wallet. The internet is not friendly with bitcoin wallets that at any slight mistake of a bug attack or malware you can go zero balance without knowing it is for this that air gap wallets are preferred safer far above any other linked to wireless communications.

Actually, protecting bitcoins or keeping our wallets safe is not too difficult, but some people are complicating matters and getting themselves into complicated situations. I have also been using Electrum for many years and even my computer is constantly connected to the Internet and I work with it every day. But I've never had any security issues or had my bitcoins stolen. I think as long as we turn on all the necessary protection layers for the Electrum wallet, don't use pirated software for our computers, don't click on strange links...we will be safe.

Even an average grandpa and grandma can click and a button and reset smartphone to it's factory settings, everyone else can install open source alternative like GrapheneOS, LienageOS or DiverstOS.
When I said old smartphone I didn't mean that it should be full of installed crap apps.
Hardware wallet is still a better option.

Electrum wallet is a good wallet, that will give you the best quality you want from a wallet to store your BTC, and you can also confirm it from those that are using it over some years till now nothing has happen to their BTC.

All you need to do which is very important to anyone that is using electrum wallet, is to write the seeds phrase down in a secure place, in case anything happen to your system, it will be easy for you to recover and continue hodling your BTC till the right time to sell come.

 Don't forget that once you expose the seeds phrase to people around you, they can make use of your coins without your approval because the power behind that wallet is the seeds phrase so do everything possible to keep them safe.

Electrum, bluewallet or sparrowwallet...as long as you are using a wallet that is open source and a non-custodial wallet are all equally secure wallets. But I think comparing them and assuming they have the same level of security as hardware wallets is not entirely accurate because hardware wallets will at least always be offline and that's what m akes it more valuable. But saying that does not mean that software wallets like Electrum are not safe because it depends on how we preserve them, but they have disadvantages compared to hardware wallets .

But no matter what kind of wallet we use to store bitcoins, much of the safety will depend on us, not because we use a hardware wallet, our bitcoins will never be hacked or lost.

The internet is an enemy of every crypto wallet that is connected to it because it would be considered hot.
Without running a full node, the electrum wallet is non-custodial and uses hot storage for safeguarding Bitcoins.
Meaning that it interacts with the Blockchain network when there is a withdrawal or deposit.

It is good advice given to disconnect from the internet unless ready to use your electrum wallet, but incase you do forget or just think of doing a fast transaction while still online, how do you think it would be easier disconnecting and doing your transactions?
It will be way better to use a hardware wallet or cold wallet like ledger or trezor that's easily tucked away from prying eyes, that is if you have good BTC investments or plan to accumulate safely and do not want to be bothered about hackers gaining access to your funds.

Yeah obviously Electrum is a good wallet, no doubt about that, but it requires one to keep the app on a device such as a smartphone or a computer to run and use the wallet to make transactions, and any app that is stored on a device can be compromised and attacked by exploiters using malware, viruses, and other stuff that they use to steal people's funds.
 
But still, one can use Electrum to store a reasonable amount of Bitcoin that one uses for regular transactions which is hassle-free because the interface is clear and user-friendly, and it is very easy to make transactions using Electrum. but for storing large amounts, one shouldn't prefer Electrum or any other software wallet even if they are open-source and non-custodial.

You can try the practices of the people who have given you this advice, just think of that advice as an alternative if you can't afford a hardware wallet. Everyone has their own way of storing Bitcoin, but the level of security needs to be prioritized to prevent unwanted things from happening.
If you can afford a laptop or other device to make it easier for you to invest in Bitcoin, it is impossible not to be able to afford a hardware wallet as a safe place to store assets. You should ask this person more about how to keep assets safe after following all his advice. If he has been doing this since 2013, it means his knowledge is very extensive and of course he also really understands how to store assets in the wallet safely.

You can run electrum on an airgapped device and have the same security as a hardware wallet.


You can use electrum as a cold storage and that has nothing to with whether you are running a full node or not.


Assuming you are using electrum as a hot wallet, you are right. Any online device is always prone to hacking.
But as I already said, you can use electrum on an airgapped device and be completely safe.

This method is good I always see it as alternative if one can't afford hardware wallet for a start, but if you have all it tAke to afford hardware wallet I think taking the steps of using hardware wallet is the Best, security is the first thing once investment is concerned mostly as valuable as Bitcoin no matter how small or big the investment is one at first should put security as the most priority because the safer the investment the more your motivation to Long term holding.

First and foremost, it's not mandatory for everyone to have  a hardware wallet unless you have to , but for the experience I think you can put it on the bucket list just to make yourself a complete crypto user :)

Honestly if it's security you concerned about then a cold wallet it what you need, anything that has to do with the internet does kind of put your coins at risk especially with Blackhat hackers and scammers working tirelessly trying to get hold of our coins forcefully... But if you don't mind the risk and have great safeguards to protect your coins then you can go ahead with the hardware wallet...btw with one of these big brands in the hardware wallet business that got compromised awhile ago, I would advice keeping all coins in one basket, spread the risk to minimise the damage!!!

Hardware wallet could be very expensive and available for people that knows how to use it or interested in it.
I think we should just stick to what works for us rather than trying to adopt another method that we could not be used to.
Hardware wallet is safe and okay to use but that does not means that other wallets too are bad. Since we are not whales then I don't seee any reason for a hardware wallet. It is mostly meant for people that have huge amount of Bitcoin and it could be unsafe if they use the normal wallet.

I want you to listen good. Using a hardware wallet doesn't mean you are 100% protected from scam or fraud or hack, the hardware wallet actually break down the probability of then getting to you because there is no internet connection to you but your own activity is what matter, you can still be careful and no scammer or hacker will get you or you can still be careless and hacker will drain your wallet or even your seed phrase carelessness and not properly backup can make you lose your coins and funds.

As for using electrum too, I wouldn't advice you that the practice is safe, you can be careful and noyhing will happen to your funds but it's not as safe like the hardware wallet. If you the amount of Bitcoin you are buying is in large amount, I will advice you to get a hardware wallet or Alternatively get a air gap device for better storage and make sure you also make a proper good use and care for it else you are as good as using a software wallet.

Yeah I completely agree with your friend that it's the internet that is the culprit of every wallet. Actually it's not the internet rather it's our unintentional actions that lead us to these kinds of mishaps.

The security layer to the wallets is good but we are not educated enough to have a good knowledge of how to use our cell phone. People get trapped by their own greed and actions. This can be resolved if we educate people of the ways in which people hack the wallets.

I don't agree, it should not be about what works for you or what you are used to, but what is safe and recommended, if you have not or cannot learn to use what is safe, then you should not buy BTC until you have that knowledge. It is not hard to use a hardware wallet, and not all hardware devices are 'expensive'.

Setting up an airgapped wallet, which is what the op is trying to do, is much more difficult for newbies to do in a safe environment, but a hardware wallet is easier for a newbie to use.

We calm down and apply strategy that's favorable for us. There's always another day to grab new opportunities in the market, today must not be the last day to grab everything. We have different strategies in the market, it's bold to pick one and implement and not jeopardize our chances of losing. Yeah you're right about this particular idea, always stick to the strategy that's favorable and not entangle with some random strategies simply because our colleagues used them.

Practically, we don't need to acquire a hardware wallet if we are just a small investor or a beginner as Electrum is enough. In fact, most of us are using this and I haven't seen or heard huge complaints about losing control of their wallet which means that the majority are safe.
We can say that an offline wallet is highly recommended and more secure but we should not push ourselves to have it or take this as the priority but rather use the money to acquire more Bitcoin. We can secure our Electrum wallet if we are too careful and avoid clicking unsolicited messages that contain links. And much more avoiding exposing our keys to other people.

How much are  you going to Keep in that wallet? because if we are talking 50 dollars worth of
Bitcoin here so what is the sense of having a hardware wallet? though this must be the practice we
need to do for us to learn and get used of safer holding , so in time that you have more to invest
hen you will have place to store them safely , in this what I mean is better to have hardware wallet
or cold storage even before we start buying bitcoin.

It is also important to keep in mind for how long you intend to keep your coins in that wallet.  Yes, for a small amount like $50 worth of Bitcoin, a hardware wallet might be overkill.  But imagine if you invested $50 worth of Bitcoin say 10 years ago? You never know how much value your bitcoins will be in the future, so it's better to take all the precautions to protect your wallet safely for a long time.

If your budget is not high, then yes Electreum wallet can really do the task. It’s the best free wallet that you can download in your pc and use it to store the Bitcoins. You also don’t need to do such tedious things, if your pc is free from viruses. I have often seen that newbies just run behind online wallets, which are actually not safe. Hence seeing a post about Electreum wallet from a newbie really made me happy.

If you can't afford to buy a hardware wallet it means that you have very little amount of bitcoin because nowadays a good hardware wallet is like $60-70, nothing crazy. Of course if you have like $20 in bitcoin it doesn't make sense to buy one. On the other hand if you have a good amount of money invested in bitcoin buying a hardware wallet would give you more security and less stress, so you shouldn't see it as an expense but as an investment.

A cold wallet is safe because it has no connection to the Internet, and transactions are made when pressing a hardware key. Although hot wallets like Metamask, Trust or Electrum do not have the function of confirming transactions with hardware keys, if you do not connect your wallet to dapps and the internet regularly, it is completely safe.

If you use cold wallets incorrectly, such as using them to link with dapps, the possibility of losing private keys is very high, and they can hack your wallet without the button of the cold wallet.  Therefore, no matter what wallet you use, it is important to carefully secure your private key. Currently, as far as I know, linking with dapps is often the easiest way to lose your private key.

I was wondering if one will be able to receive payment into the wallet under this arrangement, I mean a case where the wallet is not connected to the internet. This may sound dumb to the experienced people here but I know some few others like me see this as a major concern. So I just checked the internet to see if there will be any help as that was not addressed in the various comments here. Below is one of the answer I got so I felt I should share for the sake of other curious minds like me.

The full detail is in this link:
https://bitcoin.stackexchange.com/questions/18125/must-my-wallet-be-connected-to-the-internet-to-receive-payments

I select hardware wallet to onine wallet then take from sell point like following image

https://i.ibb.co/z28KtYn/method.png

But if we only invest 20 or 50 USD in bitcoin, what benefit will it bring because that amount is very small and insignificant. If we plan to accumulate $20 or $50 per week or per month (DCA), then owning a hardware wallet is something we should consider. Many people always think that they have too little bitcoin and that owning a hardware wallet is a bit wasteful or unnecessary, but if we have long-term plans with bitcoin, we should know that it is very important. Don't wait until we lose all our bitcoins to realize the importance of hardware wallets.

Good preparation for the purpose of keeping something good for a long time will never be a waste of time. Moreover, if it is to store Bitcoin, even though the amount is not much, it will be very meaningful when the price of Bitcoin starts to increase again in the future. So preparing the best from now on must still be considered a very important option because the good will never be in vain for anyone who uses it for a long time. Especially if over time we also have the intention to increase the amount we want to store in the same place.

What do you mean by a hardware key. If you want to make tx's in an airgapped wallet, you simply create the tx in your complementary online watch only wallet and sign the tx in your offline device. However, if it is a hardware wallet, you create the tx in your interface software wallet and sign it with your hardware device, the purpose of your offline device is to sign tx's. Take note that you can connect a wallet like Electrum to your hardware wallet.

I will advice to go airgapped.

Meaning that you will generate the wallet offline and till the end of time it will never be connected to the internet.

To be very safe from online threats you need to keep your recovery seed completely offline, don't just generate the wallet offline and that is all, you must never connect the wallet online again.

This days hardware wallets are not costly anymore, I know one company that still do discount offers since last year till today, with $100 and above you will get your hands on a good airgapped device like Keystone hardware wallet.

You have no excuse not to have a Airgapped hardware wallet today.
