i guess you can dump your private key and give it in real life, it's not connected to the web in this way

but the buyer will have no way to know how many bitcoin that key hold, maybe you can do small transaction in this way

selling private keys means that the buyer has to trust the seller because until the funds on the bitcoin address are spent there is the risk of them being spend by the seller at some point because he is the original owner and you can't trust him to delete the keys.

no man he can then move those coin on another priate key, so this possibility does not exist

Was reading a thread and started to think about ways to move bitcoin without actually being tapped into the network.

1. Buyer connected to internet,seller offers code to scan for said amount agreed on well not connected.

Any other ways to have one party not connected?

Was also looking at the wifi direct option and that looked to dicey to connect into the buyers/sellers network during a transaction.

i'm also wondering about this,and my heart have same question like you,some people mentioned about blockchain technology that can sent bitcoin without connected on internet,but i ruly not sure and stll not have proof to knowing thatw as can be done.

Even if transaction is done online, the receiver has to be on line to get the coins

not exactly, you can give to him the whole rivate key off line in real life, this is the only way to do an offline transaction

Well the transaction won't register without an internet connection so you won't really be able to 'move' the funds. I guess what you could do is have fixed amounts preloaded on separate USB sticks and sell the Bitcoin along with the stick, either that or paper wallets. However in both cases the buyer will have to trust you.

Paper wallet only option without internet connection

Thanks for the responses, the paper wallet was what I was thinking of at the time but could not think of any other way.

But other person would need to have internet to import it and send to secure address. There is not a buyer that will accept here is BTC in this paper wallet.... you can check once you get internet.

Best option I think still if no wifi is a phone wallet. I think cell towers offer a large area in most countries where you could send BTC to a buyer as a seller. Just a lot more chances of this then no intenet. Also hardware wallet on phone... keeps great security even when selling and using a mobile phone.

I just don't see a sale where you had over paper wallet and they pay you fiat money for what you say is on paper without internet to check and import.

Without internet it is not possible to make a transaction that can be trusted. Because there is no possibility to control the transaction. So at least one participant must have an internet connection.

The only possibility is after buyer have sent you the money, you create a paper wallet with the amount the buyer paid for and give him the private keys, in other words you create a paper wallet and you send him the private keys. Sounds pointless in the first place as why anyone would like to do this ?

one of you has to be connected to the network at least it can be the buyer and then you have to trust the buyer and give him bitcoin so he can spend it by sending it to his own wallet.

the methods that i have seen was codes on exchangers like btc-e that you make with the funds and give the buyer and they import it in their btc-e account and then pay you.

the other method can be giving the private keys so they can sweep the keys. but i don't see any use for offline exchange at all.

No you need to have a connection to the network as you transaction needs sent in it. You mention wifi could be dicey during buying/selling. If your talking about buying and selling in person you can use a smartphone in some cases where you use cell phone network vs wifi.

As far as security some hardware wallets can connect to phones via OTG cable and allow pretty save storage/sending even on the go.

Unless he just gives away his private key on paper to be swept into another address.
Depends on the reason why you would want the seller to be disconnected from the internet, might be pointless in the first place.

But he mentions "buyers/sellers" I can't imagine anyone accepting a paper wallet without importing. They would want to import it and send to new address. Also make sure they get a conformation so it's not a double spend.

At end of day realistically you have to have internet of some kind if you want to sell it.

The best way would be using a paper wallet. This is the most secure way, but there has to be an internet connection in for the connection to be completed. So I can not think of any way that one party can not be connected to do it, unless you are asking if both of you have to be connected at the same time.
