Not your keys - Not your bitcoin.
Keeping your Bitcoin on an exchange such as Coinbase base is not recommended, they can, and do get hacked, go bust or the government could just decide to take over. They hold the keys to your Bitcoin - not you.
Not your keys - not your Bitcoin.
Not your keys - not your Bitcoin.
Key take aways-
Do not trust exchanges or 3rd parties I.E. Coinbase, Kraken, Wirex, FTX Etc
Only trust the 12/24 word key you have created under your control

With regular money there are varying levels of security that depend on your circumstances & amounts. You may be happy keeping £200 pounds in your "hot" phone wallet but not £200,000.
Considerations before you buy should be -
Considerations before you buy should be -
- How much ? (start small)
- How fast do I need to access ?
- Single signature or Multisig ?
- How private ?
- Will you be put on a mailing list that could get hacked ?
- Have it posted to a P.O. Box
- Use a private email
Wallet Apps
Bitcoin wallet apps are the most popular and convenient method to your Bitcoin, with effortless ease and simplicity you can transact with Bitcoin, Lightning or both. These are not recommended for large amounts as they can be hacked or withdrawn from App Stores at a moments notice.
Lightning Wallets
Lightning wallets are much better for small instant payments and incredibly easy to setup. Wallets can be linked across devices eg Wallet of Satoshi (no longer available in the US) can show the balance and be used across all your Apple products effortlessly. I think these will become the norm, people may never even get as far as having an "on chain" wallet.
Wallet of Satoshi is Lightning only (which may become the norm) ,it is probably the easiest to use but the trade off is you are trusting a third party custodian, fine for ready "cash" but not your life savings. |
Multi function apps
Here's some of the best wallet apps. This is a rapidly evolving space, functionality is being added and improved all the time so please refer to their websites for the most up to date info.

Desktop Wallets
More advanced not for beginners -
|
Exodus an excellent easy to use multi currency desktop wallet where you can exchange between currencies -in app-. however alt coins are an attack on Bitcoin, so you have to question their intentions, & hence their trustworthiness.
|
In browser wallets
In browser extension wallets typically lightning only are for directly interacting with websites. You may be on a news feed where it costs a few sats to view instead of the usual dreaded adverts & privacy sucking cookies. Examples include Alby which can be installed into Firefox.
Hardware wallets.
Hardware wallets are dedicated devices that do not connected directly to the internet or only connect in a limited access way that makes it virtually impossible to hack. Some store your private keys on board. Seedsinger doesn't hold the keys once the device is unplugged, so its imperative you store your keys by physically writing them down in word form or QR code or stamped into a metal plate. Reverting to physical security, something we intuitively understand. Other hardware wallets do retain the keys when unplugged for quicker access.
Privacy tip - Do not order the hardware wallet to your home address, instead order it to a P.O. box. This way your name and address wont be on a list of bitcoiners that gets leaked or hacked.
Seedsigner - Recommended ✅
Seedsigner is my top recommended hardware wallet. It can be built from scratch with off the shelf parts & a 3D printed case. Suitable for DIY'ers that want top level security & the privacy of not being on a leaked bitcoin hardware wallet mailing list like ledger. It also protects against software wallets being removed from app stores (if governments get their way).

Coinkite Coldcard
A hardware wallet that is never connected to the internet, data is transferred via a micro SD card, so as to completely “air gaped”.

Ledger
While this WAS probably one of the best hardware wallets- Due to PRIVACY CONCERNS, & HACKING OF THEIR DECENTRALISED APPS LEADING TO LOSS OF FUNDS I DO NOT RECOMMEND Ledger.
If you still have funds on one do not use it in conjunction with the supplied Ledger live app. Only use wallet in conjunction with Wasabi or Sparrow wallet - (see vid) . Check thoroughly on the screen of the Ledger its self that the addresses & amounts are correct. Due to concerns they "could" export XPUBs and private keys 🚩 Possibly KYC AML Legislation or the wallets support for shitcoins has forced these companies to log far more privacy details than is necessary for Bitcoin only. Recent concerns over Legers recover service found that the private keys are encrypted split into 3 parts and stored on 3 different servers. This has upset the Bitcoin community because Ledger have always said this is not possible, if someone else has your keys it is possible for them to steal your coins. A huge 🚩. Ive found that as soon as companies start dealing in S#1T coins they tend to become more concerned about bottom line rather than separation of money and state. |
"Physical" Bitcoin
Physical Bitcoin Revolutionary ? A bit like handing over cash, physical Bitcoin is now a thing but how do you know they haven't copied your private key before hand ?
Opendime Opendime is a small USB stick that allows you to physically spend or give away Bitcoin like a dollar bill. Pass it along multiple times. Connect to any USB to check balance. Unseal anytime to spend online. Trust no one.

Multisig Wallets
For 10x security multi signature wallets offer the highest security. 2 of 3 multi sig requires 2 of the 3 key holders to sign a transaction. which should protect against the wrench attack (some breaks in and threatens you), or a 7 of 9 signature wallet would protect against flakey business partners.
Seed signing devices are now being used in combination with multi signature wallets. Not for begginers -

Physical security
We all know instinctively how to stuff cash under the mattress. What if you have a fire? a metal plate wouldn't burn, or second copy somewhere else would still be ok.
Foundation PassportFor people who want to buy off the shelf signing device Foundation passport .
However you will be added to a customer database, which could get leaked. Consider having it mailed to a P.O. box for privacy |
