Bitcoin Forum

I'm from Nigeria and as you all know, Nigeria is a developing country and when it comes to internet connections we're not there yet. I live in the city area but travelled to my village few days ago for an occasions. On the way, I got a call from a friend requesting to buy $550 worth of bitcoin, I tried sending the coins to his wallet (he's a regular buying so I already have his wallet) but the transaction refused to go through because their was no internet connection. When I finally got to my village the transaction went successfully because we had internet.

After this experience I thought about other remote villages in Nigeria and African countries that don't have the Internet 24hours if they were to use Bitcoin (cryptocurrency in general) for day to day transaction can this be done without the internet?

I tried searching the web but couldn't find any post that gives me a satisfying answer, so decided to contact forum user.

Edited: 04|10|2018 Can anyone verify this information, how accurate is it?.

Bitcoin is transferred after initiation from the sender of the transaction through the internet.
The sender isn’t required to be connected to the internet to sign the transaction, but he is required to be connected to the internet to declare his transaction to the network so that they can record it. A transaction even signed, if not recorded within the blockchain is equivalent of it having never occurred.
In order for the transaction to complete, it has to be recorded on the blockchain and consensus should accept it.

The receiver does not have to remain connected to the internet as the transaction happens since the sender pays the transaction fee and gets the transaction recorded in the blockchain. Once the transaction is recorded, the wallet is free to sync with the blockchain and display the funds received. Even if the person isn’t connected to the internet, the blockchain explorer shall display that the funds have been transferred to the appropriate account. Whenever the receiver needs to spend the money within their wallet for a secondary transaction, they may sign the transaction offline, but whenever their transaction is broadcasted to the network, the miner verifies that there are funds allocated or present in the wallet to initiate the transaction.

To conclude, the receiver does not need an active internet connection to eventually receive the money, but however they do need an active internet connection if they wish their wallet to reflect the funds that they’ve received. They are required to have an active internet connection to broadcast their transaction after having received bitcoin to make a secondary transaction as well.

Hello my friend, I do not think that without the Internet it is possible to make a transaction, but I heard that there were tests of bitcoin transmission via satellite.

yes

physical bitcoins. also known initially as casascius coins or paper wallets

as long as you trust the seal and that the original holder(s) do not have or know the private coins because its sealed within the physical bitcoin. then you can swap them hand to hand

I think your question once again exposes one of the big weakness of cryptocurrency. It is generally called digital currency because it involves usage with internet gadget. However, it is even better that the receiver need not be connected to the internet to facilitate the transaction. It would have been nice if there was an option of internet usage and manually. Maybe internet being for faster transaction and manual for those who don't mind waiting  ::)

I don't see it as a weakness. The Internet is everywhere and without it the world would probably plunge into chaos. Think about all those social media addicts not being able to log in, people unable to send email, millions of companies unable to work, what would happen to the richest people in the world who built their fortunes on computer software and online stores? The Internet is here to stay.

I don't think it is possible to conduct transactions with bitcoin without the use of the internet. Who knows maybe in the near future when technology advances, transactions could be conducted without the use of the internet.

Good timing on posting this question now.  Some recent advancements have just been made in this area.  The latest version of Bitcoin Core has implemented 'Partially Signed Bitcoin Transactions', or PSBT for short.  It will effectively enable users to send transactions while offline in some circumstances.

Nearly all the articles I can find on the subject are outdated now, but you can still read them to get a better idea of it:

https://bitcointechweekly.com/front/bip-174-psbt-partially-signed-bitcoin-transactions/
https://bitcoinnews.com/bitcoin-improvement-proposal-for-offline-transactions-published/
https://ethereumworldnews.com/bitcoin-improvement-proposal-bip174-offline-btc-transactions/

No Bitcoin nor any other cryptocurrency can be sent without the use of the internet because to send cryptocurrencies you need the full access of the internet to do that. The issue of constant internet supply has been a hindrance in the acceptance of bitcoin as a payment method because some countries in Africa don't have the best of internet supply.

It should be possible in the future... some developers are currently working on something like that. https://github.com/MuleTools/MuleTools
Not sure how far they have gone .


I read somewhere that you can broadcast transaction via text messages without the Internet but don't remember how exactly. Try Googling: "send Bitcoin via text" maybe you will find something useful.


You should try a wallet app called Samourai https://samouraiwallet.com . I think they support transactions via text messaging. Not sure if the feature works in every country.

No mention of this yet? https://blockstream.com/satellite/

I know it's going slightly in the wrong direction of this thread, but it might give the potential for something cheap and easy in future. As it stands I think you have to lash up various receivers and so on and it's receive only. Perhaps one day all you'll need is a box from the local market.

You could send a raw transaction by post, pigeon, fax or even over the phone. If you can use any of this to reach a working internet connection, the transaction can be broadcasted. And broadcasting isn't possible without internet.

I think, for while, you will not be able to send, receive and trade bitcoin without the internet. internet is a very important aspect in the crypto world.

but I heard that cointext makes gadgets that have services to transact without internet. cointext uses the sms protocol. and today is being tested in several countries such as in England, Sweden, Netherlands, and others.

maybe you can try using that gadget.

Where in the world do you have SMS but no internet?

Africa has basically ignored landlines and gone straight to mobile telephony including internet. If you can SMS then 3 or 4G should be available to you as well. In many areas they have better coverage than supposedly first world areas.

I believe you had observed that yourself that without internet connection, transaction may not be feasible as internet is the only tool for the cryptocurrency transactions. I think that your government may soon consider internet connection such that the people in your country could also benefit the cryptocurrency technology.

The sender need internet connection to sent bitcoin
The reciever need also an internet to verify the bitcoin transfering their wallet came from blockchain
So simple to elaborate bitcoin is made from the new technology using internet and computer without this bitcoin is useless

Yes BTC can be transferred or sent without the internet. We have a wallet known as the paper wallet which does that job but it depends on how you trust the sender before you can use it.

There is way to transfer bitcoin without the internet, using paper wallet. But, in that way, it will just take the transaction longer. What if your transaction is across the globe? Who would want to carry a sealed paper on a plane and to a certain person? It will just take longer. That is why there is internet, it will make the transaction faster.

It is not possible, because Bitcoin and the cryptocurrency is a digital money. It lives in the online network, It works in digital and digital means online here. We can't touch bitcoin, If you want to trade bitcoin then you must go for face to face trade. Otherwise, it is not possible without an internet connection. Can You able to sen Skrill or Paypal without an Internet connection? You may withdraw PayPal from the bank, but you have to deposit or send with an internet connection.

If you are familiar with paper wallets or physical Bitcoin then yes it is possible to transfer Bitcoins without the use of Internet. However, giving away paper wallets or physical Bitcoins is different from sending through internet because physical Bitcoins has a fixed value line 0.1BTC, 0.5BTC or 1BTC depends on its face value. I have a few of those physical coins, some are funded and some are none. Those that are funded can be given away as a gift.

I don't think there is a so called physical bitcoin. We all know that bitcoin and any other cryptos can only be tranfered through internet. So we can't trade cryptos without internet.

Yes i agree on that, i believe that the bitcoin is runs only through the help of the internet. I believe that the bitcoin will stop if the internet shot down. But I think internet today is really useful and slowly become a part of human life so then I believe that the government will not stop the internet.

Through physical wallet but I guess just few people would do it.
And you should really know the other person who are going to buy or sell the crypto.

I honestly just found out that there is a paper wallet, it looks like bitcoin is ready to face the world without the internet
then what is my question, how do I access the paper wallet? does it really really not need an internet connection?

Ofcourse it can! but not everyone is comfortable with paper wallets! Before u even send to a paper wallet you will need internet! I would have loved an SMS network for $Bitcoin or any other cryptocurrency! I think dev of crypto projects should start thinking in this direction, because it makes adoptability even easier! Most people can use a non internet enabled phone to send text messages and take/make calls!! these group if it can see sending of crypto as just doing a text message, it would be better for the growth of the technology! It would surprise you to know that there are millions who still can't afford a smart phone, SMS would work magic for these millions!

Google can't help you in this case. Bitcoins are meant to be online and you can only store then in various coins or cold storages which would than make them stored offline. You cannot transact bitcoins offline as they need a active internet connection to push the transaction into the block. Bitcoin transactions are pushed forward into the blockchain to process where the miners make the transactions process by solving the algorithms.

Bitcoins can be assumed as a digital currency which does not have any hard currency form (Exception: Cold storage, physical coins, hardware wallet, etc). They can only go through via the internet. You can perhaps trade for bitcoina offline if they are stored in the physical coins but it would go much hectic.

We all have a active internet connection so why shall we go for offline trading? Bitcoins are best as they are and also using and transacting bitcoins is much easier and secure online.

Bitcoin is versatile so if there's a way to send, receive and trade without internet then that would be possible. It is actually beneficial for users because it will lessen hackers and transactions will be seen.

Bitcoin is a digital currency and so it's transaction can only be carried out online though the internet.

It is a decentralized virtual currency and not fiat currency.

I think it will be almost impossible to transact bitcoin not using the internet as that would defeat the purpose of its creation.

As of now there is no way to transact or transfer bitcoin without the Internet but I read an article before that they are developing an altcoin that doesn't need an Internet to send the coin in other wallet but it still need Internet to sync his wallet to appear in the Blockchain.

No, I don't know why people are saying that you can actually transfer bitcoin without being connected to the internet. Can you search google, Use google, Download a movie without being connected to the internet? You could however buy the movie from a shop or buy a book instead of searching google, But you can never really download anything if you're not connected to the internet.

Кoнeчнo мoгyт быть oтпpaвлeны бeз интepнeтa. Изнaчaльнo биткoин был мoнeты - casascius. ;)

My own conclusions at your problem is that you already sent the transaction until you have an Internet and along the way have a connection problem but the transaction been made it is just not recorded to what gadget you were using with and on your way home the device connected through the internet and once again fully committed to the internet so far the transaction recorded sync and verified and be remind that if you were using electrum there's an option that you can spent unconfirmed balance meaning by this is that the balance not been verified via block chain could be send.

It is possible that over time the cryptocurrency market will contribute to the development of the Internet. Unfortunately, for the time being, you will not be able to perform the operations indicated without Internet access.

Physical bitcoin is like a coin that contain private key inside it, So it is like you can have bitcoin physically and carry it everywhere. I think in this forum there are people who offer service to make something like that.

I don't think Bitcoins can be sent without mining in the blockchain which uses internet as it source of power. The only way for bitcoins is sent is through the network which needs internet for validation.

as far as I know (CMIIW) but Mesh Network still really needs internet network right? Mesh network is more like a LAN network with wider coverage, but still unable to access the website server needed

I also agree.Maybe in the next years,it will be more possible to transact bitcoins even without internet connection.But for now,sending and receiving bitcoin is more dependent in the internet access.If you happen to have a poor connection,i think your transaction might not be successfully done.

For now, it needs internet in sending and receiving bitcoin because without it, we cannot do the above transactions. I think in future it is possible to send and received bitcoin, if that would happened for sure many will use it.

In many area, there is no good internet connection. I think with technology and development of cryptocurrency, i am believe bitcoin can use in area without good internet infrastructure. Internet is important thing for bitcoin to store the transaction data.

According to  Techopedia website  definition of a digital currency, is a payment method which exists only in electronic form and is not tangible.Bitcoin is Digital currency therefore to access it(send,received or trade) it must be through and electronic means,which is the internet.

No, normally you can't use bitcoin without internet. This means sending, receiving or trading it. This happens because the transaction needs to be accepted and registered by the Blockchain network.
However there could be some exceptions if you use special wallets or exchangers that could transfer bitcoin for you even without internet. But this is not anymore related to your question because you could not use internet but for the original transaction it will be used internet.

While has it stands now, Bitcoin can not be sent or traded without the internet. Blockchain technology  basically runs on the internet, thus networks of computers connected together. The key feature of bitcoin is the use of internet for the transaction of funds from one wallet to another.

If you just read post above you then you’ll find some good answer from this best poster I’ve seen in this forum,here it is mate


You have given me good enough reason to consider offline bitcoin trading and i admit that i dont have that big idea about this until i read your post so thank you

Perhaps you should get in touch with people who are busy with crypto trading in your country. So you can take the money in cash and give private key as a piece of paper. Because Bitcoin was established on the internet and you need people on the internet network to trade.

I do not think time comes that bitcoin transaction become independent from internet because it is more faster to process having it. It such hard to update the system at that manner. We have internet for the fast processing and there is nothing to change about that. Every transaction is internet dependent. However, if that possible it is good news on every people who have poor internet connection.

I'd say that there are definitely ways. For example, I recall that SMS based bitcoin transactions have been available a long time ago. The relaying of transactions using the mesh technology that you mentioned in the OP could also be a thing that would be possible in the future.

However, for now, I think that the most feasible way to send bitcoins is probably still via the internet.

I don't think this is necessarily a huge concern given the fact that in the very near future, even remote areas would likely have some form of internet coverage or another very soon. But it is a problem that some people in rural areas may not be able to access BTC - although they probably aren't even cognizant of the fact that it exists at the moment.

Yes today bitcoin can sent without internet it is called paper wallets. It is also new to me like i only heard it last week and i did some research and its a great way to trade coins. Maybe in the future they will find a way to trade without internet but still using computer.

Perhaps you need to research more about what a paper wallet is, otherwise you completely looks like a just trolling.

Its impossible to received bitcoin without internet because you have to broadcast your transaction.

Interesting project but isn't the mesh network is also indirectly working over the internet access only ? I mean its liking sending some bits over the internet and recording it for the further activity until the time mesh comes online with next connection. I am not sure how this really is working but seems to me one and the same thing at all.

I was hoping to see a answer where we will have physical appliance of the bitcoin, lets say in the form of QR Barcodes printed with specific value of the bitcoin over the paper. If you want to make the payment then just hand it over to the buyer or seller accordingly and he/she may use it whenever they want. The bitcoin could be stored over the public wallet which will act as bank. I guess something like this can work out very well.

No internet, transaction not confirmed by network. Some applications will allow validation when there is internet, some may change! To be safe, every successful transaction must be confirmed online!

If both of the person are in two different places and you want to send him bitcoins, then it is not possible to do so for now without the internet. You need to be connected to the internet to do so. Even if you manage to sign the transaction offline, it must be broadcasted to the blockchain which will require the internet. You can trade p2p with paper wallet, but the issuer must be extremely trusted.

I'm afraid you haven't been given very good advice there.

Physical bitcoins in an actual 'coin' form are generally seen as collectors' items.  It might sound like a good idea, but in practice, they're not common enough to be used on a regular basis.  The "trust" issue also shouldn't be understated.  If someone gains access the private key, that physical coin loses its value.  And since pseudonymity makes it difficult to tell who accessed the private key, someone might accuse you of trying to scam them if you inadvertently gave them a physical coin where the BTC stored inside it had already been stolen.  You would have to manually check each coin on a blockchain explorer before you try to spend it.  

Trading paper wallets is dangerous, as the person who made the paper wallet could easily keep a copy of the key.  There are serious security risks to trading physical bitcoins.  Exchanging private keys hand-to-hand is not how Bitcoin is designed to be used.  I strongly advise against doing that.

It's far safer to get a hardware wallet and then learn how to use PSBT (https://github.com/bitcoin/bips/blob/master/bip-0174.mediawiki) to send "offline" transactions from them.  And accept payments from those who have done the same.

Is the physical bitcoin function as virtual bitcoin?I mean the value of this two are the same?

And can you let me know hows this work and how can i have this since i have some bitcoin on my electronic wallet?Hope your generous enough to enlighten me about this because i am really interested having and using this physical bitcoin

You must transfer Bitcoin online. With paper wallet, it is possible to transfer money without internet, but it is not very reliable. Because someone knows more private key.

But there is a project working on it. Kora Network. You can have a look. A project that can work even with SMS codes. But I don't know how much it can happen.

I also agree. It is impossible to transact without internet because it is developed dependent into it. Even companies need internet for fast processing and transfer of documents even updating of their data. Bitcoin price needs to be updated every time because the price change daily. Remember that poor internet connection failed the transfer what more going to happen when there is totally no internet access for bitcoin. It is impossible.

Internet is a wireless connection of computers, I think it can be sent in a local network wireless or wired even it is sent web based it can be sent just like any other sharing method,  it is digital which can be shared with/without data.

No internet, we have nothing, so the transaction is confirmed need a network of Node. No internet, no Node

yeah i agree to this in fact africa because of government restriction and banning on bitcoins people trade their through wattsapp using smartphones, and with regards to offline payment yes its possible using paper wallet, but overall its internet to make paper wallet and broadcasting of transactions.

I don't think that it would be possible,
How could the system verify it if it wouldn't go through the internet?

For now I don't think bitcoin sending and receiving can be done without the internet as the blockchain is a new technology that has no physical value and no bitcoin bank yet even the blockchain that is the digital bank only exist on the internet so at that the internet is the life wire of bitcoin and the blockchain entirely.

I think you can only trade with bitcoins offline with the medium of physical coins which has bitcoins stored in them. Such use is much rare so i think that it could not be implemented that. Infact using bitcoins offline is not thay carried forward untill now and i think that bitcoins are only a currency that mist be used online.

Well, as far i know, bitcoin transaction required internet to be processed. If there is a way to send or receive bitcoin without internet,
then it will be great because you don't need to afraid in the location where internet network coverage cannot reached.

I think this is not possible.In order to access BTC internet is required.I don't this without internet or electricity using and cryptocurrency is possible.In future anything can happen but according to me doing this will not be possible at any cost.If doing this will become possible that i think it will make our work easy because in the absence of internet one can do any transaction.

The internet is a network for us to interact with each other, without the internet we will not get any information, and without the internet, there will be no blockchain or bitcoin names.

Based on the caption on that image means it still can be sent without internet because it's need the internet to execute the transaction.
So i think, we cannot do transaction without the internet

Frankly speaking we cant do what you did without Internet. There are many countries in the world which are still lacking in having a good stable Internet. Its one of the weaknesses in cryptocurrencies being used as real medium.

Bitcoin is digital currency and its only using on online-based, not your local currency.So without an internet connection, you cannot do anything. Now Bitcoin is using all over the world but it's not international currency like USD or euro so if you want to use bitcoin and send one to another person must be needed internet connection

YES! Bitcoin can be sent Offline! there's many ways of doing this actually!

First of all you need to generate the transaction offline on your QT, then you can Either;

1: put the transaction on a USB and mail it (it's slow but it works) once your friend gets the USB he can plug it in and brodcast it...to the internet tho.
2: CB radio! this really cool :) http://betteroffbitcoin.com/a-protocol-for-offline-bitcoin-over-radio-transactions/
3: diaosjd982j3mklidsjjd sdfsd omdkslfsi j9sijfo2k msdf iwioekmls kdfnieosfkl s,

however, all "receivers" needs internet at one point for the transaction to broadcast to the network.
i guess if you use option #2 and set up a hub in a city where you have internet, you could shoot all transactions to that hub and have them verified from there (automatically)


i think option #2 would probably be best for you and "small villages" but it requires some work.

If mesh network can be used for sending or receiving bitcoins, then how can we connect to the mesh network ?
Connecting the mesh network to the other's network will need internet too, right ? But if it really can be happened, it will be great for us.

I think internet is not a very big problem because nowadays internet is everywhere.But this is also true that without internet it is not possible to transfer bitcoin.There are many places in world,where internet is a very big problem but after see peoples interest in Bitcoin,many companies is researching to made software for easily transfer Bitcoin without any internet connection in future.And according to me,that day is not too far,when we can see that Bitcoin is being transferred without internet.

I think it is not possible right now to sent or received bitcoin without any use of the internet. But if the mesh network can make it possible, then it's very well thing. But how could we reach towards the mesh network without using the internet?

A big No! Bitcoin and altcoins are crypto currencies and are not having any physical existence. So that thing cannot be used as a consideration which is not physically present. So if you want to use crypto, internet connection is must.
You can request your government to provide internet facilities in rural areas.

I don't think this is possible as to the latest Technology bitcoin was built on. All transactions and access go through the medium of internet, I don't see anything been done without the access of the internet. But maybe in the later future we might have an offline bitcoin or even blockchain transaction

we really can't do anything about bitcoin when we don't have an internet network, but I'm sure when bitcoin is legal in the world the government will find a solution.

If you have a HAM radio license look into "packet radio". Code has been developed to run a node over the air. I just got licensed to find out more.

With the loss of net-neutrality it will be critical to move the blockchain off the internet. It may just be a few more years before you will pay a fee to your ISP every time you use crypto. Or perhaps it wont be allowed at all? Without net-neutrality your internet service provider has exclusive control of your internet use and can make any rule they like.
 >:(

Yes. Well, I think this is also one of the cons of bitcoin, you can not used it in some areas where internet signals are weak or did not reach. Mesh network is good to used if you have also an internet and transfer to another. But how about the remote area they can not used bitcoin to their transactions. Thats why we can not say that cryptocurrency could replace fiat.

Yeah very sure it can be sent with the paper wallet without the internet. But for the paper wallet I don't really believe in it because its not so safe for me. As for trading I don't know much about it.

I don't think that Bitcoin can be used without the Internet. I don't see the problem. While there is electricity the internet also works.

Unfortunately not, but in the future we hope to see internet covers every single corner of the world so we are able to access it anywhere anytime. That way we do not have to be worried about not being able to send/receive Bitcoin due to lack of internet.

when it to comes to innovations nothing is to much to achieve, this is possible with new innovations in the blockchain.

Yes Internet was like the brain of bitcoin when it compare to human body. No one will function without it. Just like in bitcoin, how can you going to access it or even transfer it to other people without Internet. It was also like the bridge that connect one people to another user of it.

No, It is not possible at all. Because Bitcoin is an online-based currency. It can only be traded in online with a strong network. I don't see any chance of offline transactions for with the bitcoin. You can use pocket wifi or other strong gadgets to work in villages, but without an Internet connection, you can't trade bitcoin.

Yes.I agree.Bitcoin transactions cannot be successfully done without a strong internet connection.There should be an internet access if you want to send or receive bitcoin,or trade with it.If not,you will keep on repeating your transactions again and again without realizing your goal.

I never heard about something like sending bitcoin without internet access. Because as far as i know, bitcoin and internet surely has a strong correlation.
We need internet to access our bitcoin, without internet there's no way we can use our bitcoin.
That's why i think it's impossible that we can do the transaction using bitcoin without internet.
I don't really understand how that mesh connection works or something but if really is possible maybe you can try to do it?

Lol has nothing to do directly when the government legalizes then you can use and transact bitcoin without the internet? because only by using internet media, then we can connect to the blockchain network, without the internet we cannot make transactions and spending

If some trustable company start emite promissory notes nominated in Bitcoins.

I dont really get whats the sense of offline transaction when all people are now have easy access in the internet, if theres such thing an offline transaction I will never trust it because it is easy to hack an offline system.

True. Cryptocurrency's biggest weakness is Internet. As long as there is Internet, cryptos can be used, without it, it's nothing.

Although you still own your crypto that's plus point haha

That is why many people cannot deal with Bitcoins even if they are eager to do it. There is no Internet connection in the regions and the countries when they do live.

You cant do bitcoin without internet because internet is the main requirement of bitcoin and crypto. Without that how can you trade or transact

Without internet, the possibility to send and receive Bitcoins is significantly limited now.

NO.
The most important we need for trade, sent, received etc is internet. Without internet we can't do anything regarding bitcoin. Same as us , without oxygen we can't alive.

I can not say whether it is possible to do so, but it seems impossible without the Internet because you need to enter the key without which it is impossible to get to the funds. If there is such a method I will be glad to know.

The possibility of sending bitcoin without the use of internet is not certain because the internet is the life wire of everything about bitcoin.

will not be able to . we invest must go through the internet because bitcoin is sending, exchanging, and buying and selling. very difficult without using the internet.

Those in the remote part of any country that have  no internet coverage have no business with bitcoin at the moment. I know that the rate at which we have innovative ground breaking blockchain technology project springing forth there will be such technology that will enable bitcoin transfer without internet in future.

At the moment it is really impossible. The main advantage of bitcoin is that it is concentrated on the Internet. But as you may have noticed, this is its main disadvantage.

i have no accurate idea about your questions but i think bitcoin can be sent or recieved without internet but i use internet to make bitcoin transactin.
and another thing internet is need for confirmed your transaction that you dealt with bitcoin.so my opinion is mixed yes and no both.

The Internet is an integral part of bitcoin. At this stage of its development, we cannot use it without an Internet connection. This is a weak side of bitcoin, which is yet to be adjusted. And I hope that it will be really settled.

The Internet is very important for bitcoin, as outside of it bitcoin simply can not function. Therefore, for all operations with cryptocurrency you need access to the network. But perhaps in the future this problem will be solved, as it can really create obstacles to the implementation of bitcoin as a currency.

I think all the guys here are right. We can not use bitcoin if your device is not connected to the Internet. This is the main difference between bitcoin and any other currencies.

Its really impressive , but to use it i think you need to have devices around like rooters , something like that with radius . If somebody can make it possible , then yes we can send it without internet . Same would apply with sending files and other stuff we do with internet .

Bitcoin cannot be traded with out the help of the internet. Bitcoin is a digital currency that requires the internet of things . one of the major reasons Bitcoin was built is to solve the challenges  of trans order transactions. Bitcoin is tradeable like every financial instrument on the forex market , without the internet you can not trade effectively since you are connecting to individuals or cooperate organization  within the Globe you never meant before who are ready to sell or buy crypto asset.

They are both really connected with each other, so it's impossible to separate them to make transactions or offline transaction. But if for receive a bitcoin, it's not mandatory to connected through internet, but the increasing balance isn't visible.

There should be a solution to use it without net. A lot of people still do not have regular access to the internet.

That's true, without Internet nothing is possible. You need to have an active internet connection to transfer from one wallet to another or by using an exchange.

This is possible if you store it on storage devices such as HDDs, SSDs, Ledger Nano S or other dedicated Bitcoin storage devices. The use of these devices helps you protect Bitcoin and also perform necessary transactions in LAN.
