This page is a discussion of the different ways of storing bitcoins, whether for bsave bitcoin gold purposes or as a medium of exchange. As bitcoin is a digital asset, it can be very un-intuitive to store safely. Historically many people have lost their coins but with proper understanding the bsave bitcoin gold can be eliminated. If your bitcoins do end up lost or stolen then there's almost certainly nothing that can be done to get them back.
Have your wallet create a bsave bitcoin gold recovery phrasewrite it down on paper and store it in a safe place. The wallet should be backed by your own full node. The art and science of storing bitcoins is about keeping your private keys safe, yet them still being bsave bitcoin gold available to you when you want to transact with them. It also requires verifying that your recieved bitcoins are real, and stopping an adversary from spying bsave bitcoin gold you.
In the past many people bsave bitcoin gold accidentally lost bitcoins because of failed backups, forgotten hard drives bsave bitcoin gold corrupted SSD devices. Through bitter experience it was found that one of the most practical storage mediums is pencil and paper. The private keys bsave bitcoin gold a bitcoin wallet are encoded into random words from a dictionary which can be written down.
If the your hard drive crashes you can find the paper with the mnemonic phrase and restore the entire wallet. All good wallet software asks their users to write down the mnemonic recovery phrase of the wallet. It is worthwhile to keep copies in several locations so that even if your home burns down and nothing remains you can still recover the bitcoins.
Storing a mnemonic phrase only stores private keysit cannot tell you if you have actually received bitcoins and in what quantity.
For that you need wallet software. If you received cash banknotes or gold coins as payment, you wouldn't accept them without verifying that the banknotes were genuine and that the gold was real. The same is true with bitcoin, payments must be genuine or else you may be slipped counterfeit bitcoins and be left out of pocket. The most secure kind of wallet is one which independently verifies all the rules of bitcoin, known as a full node. For receiving large volumes it is essential to use wallet software backed by a full node.
If bitcoin is digital gold, then a full node is your own personal goldsmith who checks that received bitcoin payments are actually real. Lightweight wallets which don't check all of bitcoin's bsave bitcoin gold are only appropriate for receiving smaller amounts or when you trust the sender.
See the article about full nodes. Your wallet software will also need to learn the history and balance of its wallet. For a lightweight wallet this usually involves querying a third-party server which leads to a privacy problem as that server can spy on you by seeing your entire balance, all bsave bitcoin gold transactions and usually linking it with your IP address.
Using a full node avoids this problem because the software connects directly to the bitcoin p2p network and downloads the entire blockchainso any adversary will find it much harder to obtain information.
So for verification and privacy, a good storage solution should be backed by a full node under your own control for use when receiving payments. The full node wallet on an online computer can be bsave bitcoin gold watch-only wallet that can display transaction information but does not have the ability to actually spend or steal the bitcoins. Possession of bitcoins comes from keep your ability to keep the private keys under your exclusive control.
In bitcoin, data is money. Any malware or hackers who learn what your private keys are can create a valid bitcoin transaction sending your coins to themselves, effectively stealing your bitcoins.
The average person's computer is usually vulnerable to malware so that must be taken into account when deciding on storage solutions. Anybody else who discovers a wallet's mnemonic phrase can steal all bsave bitcoin gold bitcoins, so it must be kept safe and secret like jewels or cash, in particular phrases should not be typed into any website.
Mnemonic phrases can store any amount of bitcoins. It doesn't seem secure to possibly have enough money to purchase the entire building just sitting on a sheet of paper bsave bitcoin gold any protection. For this reason many wallets make it possible to encrypt a mnemonic phrase with a password.
Some users may not need to actually move their bitcoins very often, especially if they own bitcoin as an investment. Other users will want to be able to quickly and easily move their coins. A solution for storing bitcoins should take into account how convenient it is to spend from depending on the user's needs. Hardware wallets are special purpose security-hardened devices for storing Bitcoins on a peripheral that is trusted to generate wallet keys and sign transactions.
A hardware wallet typically holds the private keys in its internal storage and is designed to be malware resistant. The device signs the transactions internally and only transmits the signed transactions to the computer. The separation of the private keys from the vulnerable environment allows the user to spend bitcoins on an untrustworthy computer with reduced risk. Hardware wallets bsave bitcoin gold be very user-friendly and are a top solution for holding private keys.
Some downsides are that hardware wallets are physical objects which could be discovered and which prove that you probably own bitcoins, this is worth considering when for example crossing borders. They also cost more than software wallets. A multisignature wallet is one where multiple private keys are required to move the bitcoins instead of a single key, avoiding a single point of failure.
These private keys can be spread across multiple machines in various locations bsave bitcoin gold the rationale that malware and hackers are unlikely to infect all of them. The multisig wallet can be of the m-of-n type where any m private keys out of a possible n are required to move the money. For example a 2-of-3 multisig wallet might have your private keys spread across a desktop, laptop and smartphone; any two are required to move the money but the loss of any one does not result in loss of money especially because they can be restored from paper backup.
Multisignature wallets have the advantage of being cheaper than hardware wallets bsave bitcoin gold they are implemented in software and can be downloaded bsave bitcoin gold free, as well as being convenient as all keys are online and the wallet user interfaces are typically easy to use. Wallet software Electrum and Armory can create multisig wallets. Hardware and multisignature wallets can be combined by having a multisignature wallet with the private keys held on hardware wallets; after all a single hardware wallet is still a single point of failure.
Cold storage and multisignature can also be combined, by having the multisignature wallet with the private keys held in cold storage to avoid them being kept online. A cold wallet generates and stores private wallet keys offline on a clean, newly-installed air-gapped computer. Payments are received online with a bsave bitcoin gold wallet. Unsigned transactions are generated online, transferred offline for signing, and the signed transaction is transferred online to be broadcast to the Bitcoin network.
This allows funds to be managed offline in Cold storage. Used correctly a cold wallet is protected against online threats, such as viruses and hackers. Cold wallets are similar to bsave bitcoin gold wallets, except that a general purpose computing device is used instead of a special purpose peripheral.
The downside is that the transferring of transactions to and fro can be fiddly and unweilding, and less practical for carrying around like a hardware wallet. A hot wallet refers to keeping single-signature wallets with private keys kept on an bsave bitcoin gold computer. Most bitcoin wallet software out there is a hot wallet.
The bitcoins are easy to spend but are maximally vulnerable to malware or hackers. Hot wallets may be appropriate for small amounts and day-to-day spending. Custodial wallets are where an exchange, broker or other third party holds your bitcoins in trust. The number one rule to storing bitcoin is this: There are many many historical examples of loss bsave bitcoin gold to custodial wallets: Web wallets have all the downsides of custodial wallets no direct possession, private keys are held by a third party along with all the downsides of hot wallets exposed private keysas well as all the downsides of lightweight wallets not verifying bitcoin's rules, someone could send you bsave bitcoin gold billion bitcoins and under certain conditions the dumb web wallet would happily accept it.
Someone who needs the easy access of a web wallet should download a lightweight wallet like Electrum. So-called paper wallets are an obsolete and unsafe method of storing bitcoin which should not be recommended to beginners. They promote address reuse and require unwieldy and bsave bitcoin gold live OS system boots to be safe, bsave bitcoin gold risk bsave bitcoin gold by printers, and typically rely on Javascript cryptography. Paper wallets also do not provide any method of displaying to the user when money has arrived.
There's no practical way to use a full node wallet, users are typically driven to use third-party blockchain explorers which can lie to them and bsave bitcoin gold on them. A bsave bitcoin gold better way bsave bitcoin gold what paper wallets do is to use mnemonic phrases instead. This means storing your encrypted or not wallet file on a cloud storage solution such as Dropbox, or emailing them to yourself on gmail. This very similar to trusting a custodial wallet service, and is not recommended for the bsave bitcoin gold reasons.
You might say you use encryption for two-factor authentication, but uploading the wallet to the cloud reduces this to one-factor. Those articles recommend using GPG for encryption or a printer, instead a better solution is mnemonic phrases. An interesting unconventional solution. The idea is to use time-lock contracts to create a wallet which cannot be spent from until a certain date. One possible use-case might be by a gambling addict who locks up money for paying bills for a month, after a month has passed and their time-lock wallet is opened they use that money for paying bills instead of gambling.
Time lock wallets don't exist yet except for simple javascript pages which rely on Javascript cryptography and are therefore not safe. If you intend to store a very large amount of bitcoins, for example in a business, you should consider paying for security consulting. Stored bitcoins are not secured bsave bitcoin gold mnemonic phraseshardware walletsmultisignaturepasswords, hash functions or anything like that; they are secured by people.
Technology is never the root of system security. Technology is a tool to help bsave bitcoin gold secure what they value. Security requires people to act. A server cannot be secured by a firewall if there is no lock on the door to the server room, and a lock cannot secure the server room without a guard to monitor the door, and a guard cannot secure the door without risk of personal harm.
Bitcoin is no different. The technology discussed on this page is only a tool to tip the scales in the defender's favour. Either your own, or employ guards, or use a safety deposit box, or rely on the police forces and army; or whatever may be appropriate and proportionate in your situation.
If someone physically overpowers you then no technology on Earth can save your bitcoins. You can't be your own bank without bank-level security.
