Tell me your offer!

I am looking to buy either of the two cards (rx 580 8gb or 5700 xt 8gb) Sapphire Brand preferably .
If you have any offers tell me what prices you can give me and at how many pcs.
I would be interested to buy 50-100 in the beginning and after that I would buy 200 more.
Thanks in advance!

There are people that had problems with HW wallets. A few days ago a guy lost 386 eth and he is not the only one. The problem I see with HW wallets is that you have to connect it to pc which can't be airgapped. I know that you need to physically approve but he said that he's done everything properly and he is not the only one. Another guy tried to connect after 4-5 months to check his account but at that time there were problems with the ledger and he couldn't see the balance. After a while (couple of months from what I remember) he checked again to see the balances and seen that it was a transfer made exactly the day he checked the acount (few months before). If the phone its tampered it stays offline anyway so I think its better with a phone/pc because you never connect it, only use it for signing. On the other hand the ledger has to be connected, therefore there is always a chance for new malware to come in. Maybe today there are no malwares that exist to steal your money from the ledger but because you connect it every time you have the chance that someone creates a malware that is bypassing the ledger rules. Idk, as I said I really dont know coding but I kind of use my logic and it seems that ledger is not better than airgap device even if the device it's a phone.
About the part of being hard and giving me headaches I don't really care, I like to learn and trust me that if I lose the money there would be no higher headache than that ) . I love to get headaches that I can deal with than headaches than you can do nothing about.

Thanks all for replies and taking your time to explain it to me.
Wish you all the best!

Thanks for reply,
Yes when I say 2 devices I mean 1 phone having the app Airgap vault which does have the private key.
The other phone would have the Airgap Wallet installed which would send the transaction by QR code and then I sign it with the airgapped phone (airgap vault app).
1. question here (maybe very stupid question for you but I cant find a logic answer in my mind): I downloaded the app and right after that I went in airplane mode . After being in Airplane mode I configured the Airgap Vault on the phone and received the 24 words seed phrase along with the recovery key and I also created my cryptocoins addresses. Now my questions is , since I ve done all of this completely offline how will the blockchain know about my address and private key? I don't understand how something that was created on an airgapped device completely out of the world can be a part of the blockchain which only exists online, I think . Now I am afraid to send the money to that address because I don't know if it should've been done while I was still online or the way I did it was the right way to do it.
I want to mention that for security I reset the phone to factory and connected it to a safe network(as it can be these days) to be sure there is no malware. But still, the only way to have the app installed was to connect it to a network therefore it was not airgapped, reset and never went online . This way I think malwared could have come either from the network , or from the app itself I suppose... Would be a better idea to transfer the files through bluetooth , sd card or anything else ?

2.About the airgap pc , I've read that when you send the transaction to the airgap pc you can also have the malware that's why would be better to use unwritable usb or cd's and destroy after every use. But if the malware is there it can send information through various ways: Electromagnetic,Acoustic,Thermal,Optical. What can it be done to be secured 100% against these methods in the case you take the malware .

3.My concern is that trough these methods they can take maybe more easily the private key from a phone. Or maybe not because you don't have to send the transaction physically therefore there is no possibility for malware infestation unless it was there before first setup. Am I right? In this case 2 phones using qr codes would make it safer than an airgapped pc?

4.My last question is , if I use the phone as an Airgapped device should I try to destroy bluetooth/wifi/antennas hardware (if there is any way) or is it safe to leave it as it is? I don't know if there is a way for the hacker to disable my airplane mode and making my phone go online to steal my private key.

Sorry if I sound too dumb but I am a very curious person and also want to have the best security possible. I also do have friends that use crypto and sometimes they rely on my advices as they are more novice than me and I want to be able to give them the best solutions to keep their money safe.

Thank you very much for your time!
 

Hello,
I would like to know how safe is the Airgap wallet if it is used on 2 devices. Basically 1 device its completely offline therefore acts as an airgap computer.  Of course there still is bluetooth and wifi but from what I know its harder to insert a malware in a phone and also the phone will stay on airplane mode all the time. Now , I am not an expert and I don't know how really these things work that's why I ask you.
Also can you tell me when you have to sign the transaction with the qr code is there any way the app can display the address you want to send but in fact the app is sending to another address? Or is there any way for a man in the middle to interfere with the app and steal the money even during the transaction or at any other time?

A hardware wallet is not really an option for me as it can pe tampered and I also don't trust ledger security because I've heard people complaining about them.
My second option would be an airgapped pc but I also heard there are ways to extract private key from that airgapped pc. Assuming that your airgapped pc was infected already with a malware it can send electromagnectic signals to an infected phone and steal that key. And I heard there are other ways too.
I am a bit confused and I don't really know coding but if someone who really knows about this can help me I would really appreciate.
Thanks in advance and all the best!

Hello,
I would like to know what would be the best option to store either eth or btc.
I have read all you said and I understand that an Air Gapped computer would be best but then how do you transfer funds if you need to? My guess is that you only connect it to the internet when you need to, right?  But I think this way the hacker can interfere exactly when you connect it and steal everything .  Maybe 2 networks would solve this problem? I do have 2 networks but from time to time I am forced to use the other one  therefore I dont have a network that it is not used 100%
I have seen that there is an airgap wallet made for tezos, btc,  eth etc. that uses 2 phones . 1 phone for cold storage with no conections (no sim and airplane mode activated probably or even shut down) and the other phone which is your daily phone . I think this would be a better choice because when you do a transaction you can use network from SIM which I suppose that it is more secure. I am not an expert so thats why I want to ask for your opinion but in my mind this seems to be a better way than computers because I know that phone are harder to hack (unless you have an app installed) and also because of SIM network.
Hardware wallets still have to connect to a computer and as we can see in this post they are not really safe... even with an airgapped computer you still need a network to dowload ledger live , update software etc.

In conclusion , am I right about 2 phones being more secure or would it be better to have a hardware wallet (ledger) connected to an airgapped computer? (What I didn't take in consideration is that the app itself could be malicious maybe... I don t know , thats why I ask ) . Sorry if I sound dumb )
If airgapped computer with ledger is the answer can you please tell me what a proper airgap setup would mean and how should I do it?
Thanks in advance!
All the best

EDIT: I seen that moccacino said that with a dedicated pc you dont even need a ledger. "get a dedicated pc for your wallet, just do a clean install, remove the network card (or deinstall the drivers), install the latest version of bitcoin core or electrum by following an airgapped setup walktrough and you'll have a wallet that tops a hw wallet when it comes to security. Just make sure you do it right... There are several ways you can mess up an airgapped setup... Ah, and make sure you keep a backup of your seed or wallet.dat on a couple usb sticks which you only plugin in your offline airgapped machine (and use a strong password to encrypt them"
Just a couple of questions here
1. How to install bitcoin core/electrum without network? Even if you take the file on usb from another computer from what I know a trojan/virus can migrate to that usb and the moment you insert it in your airgap pc its done (I could be very wrong)
2. How to make transactions if there is no connection to internet? (another ISP or is there a way to see if the network is safe? )
3  What it means to have a backup of seed? If I am writing the seed on a paper isn't that enough or going this way you cant recover the wallet with the seed?
4. Where is the password needed ? Folder password for wallet.dat or no ?
