Storing bitcoins
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 risks 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.
The best way to store bitcoin is to either use a hardware wallet, a multisignature wallet or a cold storage wallet. Have your wallet create a seed phrase, write it down on paper and store it in a safe place (or several safe places, as backups). Ideally the wallet should be backed by your own full node.
Introduction
Storage of bitcoin can be broken down in a few independent goals:
Protection against accidental loss
Verification that the bitcoins are genuine
Privacy and protection against spying
Protection against theft
Easy access for spending or moving bitcoins
The art and science of storing bitcoins is about keeping your private keys safe, yet remaining easily available to you when you want to make a transaction. It also requires verifying that you received real bitcoins, and stopping an adversary from spying on you.
Protection from accidental loss
In the past many people have accidentally lost bitcoins because of failed backups, mistyped letters, forgotten hard drives, corrupted SSD devices, or numerous other slip ups.
The key to protecting yourself from data loss of any kind is to have redundant backups so that if one is lost or destroyed, you still have others you can use when you need them. All good wallet software asks their users to write down the seed recovery phrase of the wallet as a backup, so that if your primary wallet is lost or damaged, you can use the seed recovery phrase to restore access to your coins. If you have more than one backup location, they should be in places where various disasters won't affect both of your backups. For example, its much better to store two backups in a home safe and in a safe deposit box (as long as your seed is protected by a passphrase) than to store two backups in your bedroom and one in your garage.
Also important is regularly verifying that your backup still exists and is in good condition. This can be as simple as ensuring your backups are still where you put them a couple times a year.
The best practices for backing up a seed is to store the seed using pencil and paper or metal seed phrase backup and storing in multiple secure locations. See Seed_phrase#Storing_Seed_Phrases_for_the_Long_Term for details.
Verification and privacy
Storing a seed phrase only stores private keys, but it cannot tell you if or how many bitcoins you have actually received. For that you need wallet software.
If you received cash banknotes or gold coins as payment, you wouldn't accept them without inspecting them and verifying that they are genuine. The same is true with bitcoin. Wallet software can automatically verify that a payment has been made and when that payment has been completed (by being mined into a number of blocks). The most secure kind of wallet is one which independently verifies all the rules of bitcoin, known as a full node. When receiving large volumes, it is essential to use wallet software that connects to a full node you run yourself. If bitcoin is digital gold, then a full node is your own personal digital goldsmith who checks that received bitcoin payments are actually real. Lightweight wallets have a number of security downsides because they don't check all of bitcoin's rules, and so should only be used 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 your 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 blockchain, so any adversary will find it much harder to obtain information. See also: Anonymity
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 a watch-only wallet. This means that it can detect transaction involving addresses belonging to the user and can display transaction information about them, but still does not have the ability to actually spend the bitcoins.
Protection from theft
Possession of bitcoins comes from your ability to keep the private keys under your exclusive control. In bitcoin, keys are money. Any malware or hackers who learn what your private keys are can create a valid bitcoin transaction sending your coins to themselves, 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 seed phrase can steal all the bitcoins if the seed isn't also protected by a secret passphrase. Even when using a passphrase, a seed should be kept safe and secret like jewels or cash. For example, no part of a seed should ever be typed into any website, and no one should store a seed on an internet-connected computer unless they are an advanced user who has researched what they're doing.
Seed 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 without any protection. For this reason many wallets make it possible to encrypt a seed phrase with a passphrase. See Seed phrase#Two-Factor_Seed_Phrases
Easy access
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.
Summary
In summary: bitcoin wallets should be backed up by writing down their seed phrase, this phrase must be kept safe and secret, and when sending or receiving transactions the wallet software should obtain information about the bitcoin network from your own full node.
Types of wallets
Hardware wallets
Main article: Hardware wallet
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 holds the seed in its internal storage and is typically designed to be resistant to both physical and digital attacks. The device signs the transactions internally and only transmits the signed transactions to the computer, never communicating any secret data to the devices it connects to. The separation of the private keys from the vulnerable environment allows the user to spend bitcoins without running any risk even when using an untrustworthy computer. Hardware wallets are relatively user-friendly and are one of the best ways to store bitcoins.
Some downsides are that hardware wallets are recognizable physical objects which could be discovered and which give away that you probably own bitcoins. This is worth considering when for example crossing borders. They also cost more than software wallets. Still, physical access to a hardware wallet does not mean that the keys are easily compromised, even though it does make it easier to compromise the hardware wallet. The groups that have created the most popular hardware wallets have gone to great lengths to harden the devices to physical threats and, though not impossible, only technically skilled people with specialized equipment have been able to get access to the private keys without the owner's consent. However, physically-powerful people such as armed border guards upon seeing the hardware wallet could force you to type in the PIN number to unlock the device and steal the bitcoins.
Multisignature wallets
Main article: Multisignature
A multisignature wallet is one where multiple private keys are required to move the bitcoins instead of a single key. Such a wallet can be used for requiring agreement among multiple people to spend, can eliminate a single point of failure, and can be used as form of backup, among other applications.
These private keys can be spread across multiple machines in various locations with 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 of which are required to move the money, but the compromise or total loss of any one key does not result in loss of money, even if that key has no backups.
Multisignature wallets have the advantage of being cheaper than hardware wallets since they are implemented in software and can be downloaded for free, and can be nearly as convenient since all keys are online and the wallet user interfaces are typically easy to use.
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.
Cold storage wallets
Main article: Cold storage
A cold wallet generates and stores private wallet keys offline on a clean, newly-installed air-gapped computer. Payments are received online with a watch-only 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 hardware 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.
Hot wallets
Main article: Hot wallet
A hot wallet refers to keeping single-signature wallets with private keys kept on an online computer or mobile phone. 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.
A user might have a spending account hot wallet for day-to-day convenient spending with the majority of their funds on a savings account which is stored with much more security (cold storage / hardware wallet / multisignature).
Bad wallet ideas
Custodial wallets
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: if you don’t hold the private keys, you don’t actually own the assets. There are many historical examples of loss due to custodial wallets: Bitcoinica, Silk Road, Bitfloor, MTGOX, Sheep Marketplace, BTC-e, Bitstamp, Bitfinex, Bithumb, Cryptsy, Bter, Mintpal and many more
"Isn't it just like keeping your money in a bank?"
The following is a quote of waxwing on reddit:
There are trade offs with everything, but trusting Coinbase with your Bitcoin is not the same as trusting a bank with your dollars:
Suppose 5 people are needed to access the funds, within Coinbase, e.g. the CEO, the tech lead engineer and 3 other senior employees. Suppose one day they wake up and decide to be evil and move all the Bitcoin to some private account of theirs, and perhaps make up a story in the press about how they've been "hacked". You have a serious problem, as you might find there is a protracted legal battle (see MtGox), but you can't actually retrieve the funds unless in some way the company is re-stocked with Bitcoin, or perhaps an equivalent in fiat.
If on the other hand you controlled the funds with a majority of keys in a multisig i.e. you own both of the two needed keys of a 2-of-3 multisig, then it would always effectively be your bitcoin, even though the third key may belong to a trusted third party custodian. But this also comes with the responsibility that if you get hacked, you lose all your funds. That is why it's prudent, in a 2-of-3 multisig where you have the two needed keys, to have them in separate systems/locations. If one of them fails, you can go to the custodian to supply the third key and transfer your funds again to safety. But the custodian alone, cannot touch your funds just by virtue of having the third key.
Now, if your bank gets hacked similarly - 5 key operatives in the bank decide to swipe your money and pretend it was external hackers - SWIFT transfers are made to accounts in Russia and China. Here it will always ultimately be at the discretion of legal agencies whether you "actually" still have the money that is stolen. Because dollars are not real, they can be created at a whim, and while reversing international transfers is not quite so simple, very often that reversal can be achieved (e.g. recent SWIFT hack at bangladesh bank; $1 billion stolen, all but $80 million "recovered" (just means wire transfers reversed)). Added to that consider that fiat money is insured, so even when transfers can't be reversed, the money can be "recovered". If too many banks get hacked all at once the Federal Reserve and the government together can make up some "fund" that magically reassigns balances any time they like, with sufficient political will (that's essentially what was happening in 2008 TARP etc).
So far no insurance company has ever paid out on a Bitcoin company's claim. Worth considering also.
You might say, since it's risky both ways, why not trust Coinbase? Aren't they more competent in security than me?
Almost certainly, but this argument has two massive holes in it: (1) because they concentrate funds they are a massive target for hackers, while you are not - at all. (2) they are a trusted third party so the situation is strictly worse - not only do you have to trust their security skills, but you also have to trust them not to steal (modulo multisig, as mentioned above) (edited to add: as well as literal stealing, there is things like political confiscation, don't forget).
Web 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 keys), as well as all the downsides of lightweight wallets (not verifying bitcoin's rules, someone could send you a 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.
Paper wallets
So-called paper wallets are an obsolete and unsafe method of storing bitcoin which should not be recommended to beginners. They simply store a single private/public keypair on paper. They promote address reuse and require unwieldy and complicated live OS system boots to be safe, they risk theft 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 spy on them.
A much better way to accomplish what paper wallets do is to use seed phrases instead.
Cloud storage
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 same reasons. You might say you use encryption for two-factor authentication, but uploading the wallet to the cloud reduces this to one-factor. Furthermore, there are a variety of ways in which 2FA can be compromised, in particular SMS-based 2FA, such as via a SIM-Swap.
Removable media
This refers to storing wallet files on removable media like SSD or hard drives.
"Physical" Bitcoins
Physical Coins and other mechanism with a pre-manufactured key or seed are not a good way to store bitcoins because they keys are already potentially compromised by whoever created the key. You should not consider bitcoin yours if its stored on a key created by someone else. It only becomes yours when you transfer the bitcoin to a key that you own and exclusively control.
Other ideas
Time-locked wallets
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. This is the equivalent proposal towards compulsive shoppers to freeze their credit card in a block of ice, so when they feel the urge to immediately buy something they see on the TV, they will need to wait for the block to melt until they can retrieve the credit card to be able to place the order. This hopefully gives them the time to cool off, and reconsider an otherwise meaningless purchase.
Time lock wallets don't exist yet except for simple javascript pages which rely on Javascript cryptography and are therefore not safe.
Consulting
If you intend to store a very large amount of bitcoins, for example in a business, you should consider paying for security consulting.
The 5 dollar wrench attack
It's sometimes said that all this security is worthless because the $5 wrench attack can be used.
There are multiple ways that can be utilized to beat this attack: by hiding, by defending yourself, by not letting others know your Bitcoin wealth or holdings, or by implementing security procedures which would prevent you from being able to surrender funds in such an attack, thereby reducing the appeal for an attacker to perform such an attack in the first place.
Stored bitcoins are not secured by seed phrases, hardware wallets, multisignature, passwords, 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 people 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. Following from this principle, the way to beat the $5 wrench attack is to bear arms. 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.

рулетка bitcoin monero курс download bitcoin bitcoin trend To be accepted by the rest of the network, a new block must contain a proof-of-work (PoW). The system used is based on Adam Back's 1997 anti-spam scheme, Hashcash. The PoW requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target.:ch. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is the ascending natural numbers: 0, 1, 2, 3, ...:ch. 8) before meeting the difficulty target.ethereum настройка Cloud mining or cloud hashing enables users to purchase mining capacity that of hardware in data centres.yota tether ethereum перевод pow bitcoin bitcoin play bitcoin cryptocurrency bitcoin софт bitcoin trader ubuntu bitcoin top cryptocurrency bitcoin расшифровка transactions bitcoin bitcoin millionaire bitcoin kurs ethereum продать froggy bitcoin bitcoin school bitcoin rub

An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy. Privacy in an open society also requires cryptography… We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor's younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor. We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do. We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.'bitcoin rotators

However, if your cryptocurrency account or wallet has been compromised and your bitcoins have been stolen, the owner would be unable to recover his coins. The reason for this is that most digital currencies are decentralized and do not have the backing of a central bank or government.

монета bitcoin bitcoin стоимость bitcoin капча 777 bitcoin пул monero If Bitcoin reaches a six figure price level with 19 million coins in total, that would put its market cap at just under $2 trillion or more, above the largest mega-cap companies in the world today. It would, however, still be a small fraction of 1% of global net worth, and about a fifth of gold’s estimated market capitalization (roughly $10 trillion, back-of-the-envelope), so it’s not unfathomable for Bitcoin to eventually reach that height if there is enough sustained demand for it. During the late-2017 cryptocurrency mania, the total market capitalization of the cryptocurrency space reached over $800 billion, although as previously mentioned, Bitcoin’s share of that briefly fell to under 40% of the asset class, so it peaked at just over $300 billion.заработок bitcoin On 25 March 2014, the United States Internal Revenue Service (IRS) ruled that bitcoin will be treated as property for tax purposes. This means bitcoin will be subject to capital gains tax. In a paper published by researchers from Oxford and Warwick, it was shown that bitcoin has some characteristics more like the precious metals market than traditional currencies, hence in agreement with the IRS decision even if based on different reasons.ethereum цена blockchain bitcoin keystore ethereum ru bitcoin bitcoin funding bitcoin pools
