The most secure wallet without downloading blockchain

[bartekjagoda]

Question is so simple to say but not so easy to be cleared by a noob like me.
I have to setup my first BTC wallet.
I can't store 243 GB of blockchain.
So which is actually the most secure wallet that works without forcing me to download the blockchain?

Setup means what?

Did you generate it with vanitygen?

DID YOU MOVE 10K OR moore worth of bitcoin?

Did you use multisig or segwit or legacy?

The most secure is to setup you orwn private key, sign the transaction offline, and move the coins by broadcastin the transaction from a usb

No, the most secure setup is do more or less what you suggested, but transfer the unsigned and signed transactions via QR codes and webcams, ie. take no risk with an airgapped machine.

I think this is extremely secure:

or this:

But might not be for everyone

I have never had of both of these before. If they are extremely secure then I am wondering why they are not so popular or mostly talked about here.
Are the wallets still new in the game?

If it's the case they i would rather stick to the popular ones that have been around for a couple of years.

I have. The first is basicaly a 78-page PDF guide: https://glacierprotocol.org/assets/glacier.pdf with some scripts. It's fine and it's not a new thing, but I don't recommend it to newbies, as the entire instructions are overly long and drawn out for newbies. But they themselves claim it's for those holding bigger amounts of money, so it's less of a problem.

Coldcard wallet also isn't an unknown piece of hardware, even if it's nowhere near as known as Trezor or Ledger wallets.

Both of these methods are extremely secure, but never ever use a protocol or method that you don't understand fully. Otherwise the risk of losing your coins is bigger than getting robbed.
I don't recommend any of those 2 methods unless you know what you are doing OR invest time to understand these methods (they are very well documented). And I recommend to only use these methods if you store a large amount of BTC (more than 20% of your total savings).

Here is what I think would fit to most users and is still very secure:

- Buying a Ledger from the official website
- Writing down your seed (24-words) and put them in an hologram sealed envelope, so you will be aware if someone took a peak at it.
- Leave a small amount of funds on the main seed and the rest of your savings behind a 6-8 word passphrase (Ledger has tutorials how to do that). So even if your seed gets compromised, your main savings would be safe.
- Store this envelope with your seed in multiple locations that you trust. If you do not have different locations that you trust, buy a password protected USB stick and store your seed on there from an airgapped machine. And put this password protected USB stick at the unsafe location (replace them every 5-10 years as they might die).
- Never store your passphrase at the same location as your main seed.

You went overboard with that one.

Personally, I opt for using blockchain's wallet as a hot wallet, I don't keep a lot of funds there always less than a 100$  and for long term storage I have electrum wallet on an unnetworked old computer, it was working fine just got old, so I no longer use it anymore, it isn't connected to the internet, I only connect it on an as-needed basis.

In that case your computer IS connected to the Internet. You can't consider your setup to be an offline setup if you connect it to the Internet from time to time. Only if it has never gone online you can truly say that it is cold storage.

Edge Wallet probably best non-custodial mobile wallet. Full control of your keys and complete privacy.

What I've used so far are Electrum for both desktop and Mobile, as well as the Bitcoin Wallet for Android.

Take the proper precautions as others have already said, on mobile try to stick to your own data, such as your own home wifi or mobile data. Avoid using public wifi when using your mobile wallets.
