If you have crypto then you are an ideal target for phishing scams. Facebook and Twitter are just two of many avenues that hackers scour for potential victims.
It has become common to see fake crypto exchange emails or ICO fundraising confirmations circulating such as the example below. It is best to NEVER open suspicious attachments or provide credentials through email and to always closely inspect the logo, wording and send address of any emails received that pertain to financial accounts or that request sensitive information.
When in doubt, navigate to the legitimate exchange or web service that the email supposedly originated from and contact their support team to inquire on the validity of what you received before taking further action.
This brings us to the general best practices portion of this guide. Malware is everywhere on the internet and regardless of your attention to detail, sooner or later you are likely to fall victim to some type of malicious software.
As such, it is best to have active antivirus subscriptions on your devices and to run periodic scans. I personally like to run Malwarebytes and Roguekiller on my PC once each week and have background scans on my phone that run each automatically.
Generally speaking Windows is the least secure OS, primarily due to the fact that it is the oldest and most pervasive OS in use today. Many security conscious techies tend to prefer Linux or iOS for this reason.
This category is how most people have been compromised and lost money in crypto. Primarily, by treating an exchange Coinbase, Binance, Bittrex, Poloniex etc.
While some users of these exchanges have been ameliorated to an extent, many are still suffering from the partial or even total loss of crypto funds that they held on these exchanges at the time of the hacks.
Our advice is to hold crypto on hardware and back it up using a steel wallet. If you wish to trade on exchanges, only do so with funds that you are potentially willing to forfeit entirely should either the exchange or your individual account become compromised.
A few of our recommended hardware wallet manufacturers are Ledger and trezor. You can find our more detailed wallet reviews here. The Subject of Secure storage is something we cover in much greater depth in the next Bonus Chapter.
Security on the web is akin to game of whack-a-mole and your level of security will likely scale accordingly with the amount of sensitive data or crypto assets that you are protecting.
Whether you're trading cryptocurrencies on a daily basis or you're a long-term bitcoin investor, cold storage can be a useful tool for keeping your crypto safe.
In order to get a handle on what cold storage actually is, it's important to review the fundamentals of the "bitcoin wallet.
Instead of needing to trust a third party to keep your cryptocurrency secure, you can use a bitcoin wallet as your sole gateway to the decentralized network.
There's no need to ask a branch manager for permissions when you want to transfer bitcoin, there aren't any annoying forms to fill out, and transfers happen within minutes.
As you can see, bitcoin wallets are incredibly useful. All of this begs the question, however, of how many different types of bitcoin wallets there actually are.
The phrase "hot wallet" refers to any bitcoin wallet that requires the internet to function properly. Hot wallets derive their name from the fact that they need electricity to work.
If the power goes out, then so does your hot wallet. For example the popular mobile wallet BRD is an example of a hot wallet. Not only do cold wallets work without an active internet connection, but many cold wallets don't even need a computer.
Cold wallets have several similarities to traditional physical wallets, but they also have a few differences. In general, "cold storage" refers to any bitcoin storage device that does not require electricity.
A cold storage device can be a physical box, a piece of paper, or a list of numbers and letters that you keep in your head. Thus, hot wallets are an example of hot storage devices, and cold wallets are an example of cold storage devices.
When it comes to choosing a cold storage wallet that can help keep your bitcoin secure, the most popular choices tend to be:. Hardware wallets include USB sticks and other digital storage devices that you can use offline.
Typically the private key to coins is never exposed to the internet because the device itself is air gapped.
The steel wallet is literally a piece of indestructible stainless steel that you can use to carry your bitcoin private keys or backups in. This makes it an excellent choice if you're concerned about losing paper or live in an area with lots of flooding, fires or earthquakes.
Steel wallets are interesting because they can act as both a "paper wallet" or as a backup for any kind of Bitcoin wallet in case yours is lost, stolen, or destroyed.
Almost any cryto holder can benefit from one of these steel wallets regardless of how they choose to Store their coins.
If you're concerned about malicious computer hackers getting access to your wallet, then a paper wallet is one of your best options.
There are many ways to get a paper wallet wrong - all of which can result in a total loss of funds. Proceed at your own risk. As the world's first bitcoin credit stick, the OpenDime device lets you spend your bitcoin balance in the same way that you would use a traditional credit card.
The open dime is very much like a Bitcoin piggy bank. You can add as much bitcoin to it as you want and as many times as you want, however you can only spend from it once.
At that point, the private key is exposed and the funds are no longer safe on the hardware. Because of this, its best to send all the coins to a new address once you are ready to use them.
So now you know of all the different options when it comes to choosing between cold storage wallets. Let's compare them all to each other to see which one would be best for you.
Technically speaking, hardare wallets fall somewhere in between a traditional hot wallet and a pure cold storage device.
With hardware wallets, the private key is stored digitally on a microchip, like a hot wallet. But that chip is never exposed to an internet connection.
Hardware wallets can be a bit easier to carry around and make transacitons with, but they are also subject to data degradation risks.
This is why many users pair them with a steel wallet as a backup. When it comes to state-of-the-art bitcoin cold storage, steel backups are definitely ahead of the curve.
Steel wallets provide the convenience of the paper wallet with the portability of the hardware wallet, but they also come with some added security features that make them worth looking into.
They can be used to backup any kind of hardware or software wallet. Typically these wallets spit out a 12 to 24 word phrase you can use to get your coins back if your main wallet is lost, stolen, or destroyed.
They can be used as a more sturdy version of a paper wallet. After you have generated your paper wallet, you can recreate the private key in the steel wallet using the provided tiles.
Afterward you can keep the paper Wallet with the steel wallet and if there is ever a fire or a flood, you have a copy of the paper wallet that will survive.
In the video below, you can see Billfodl the most popular steel wallet get put through several tests. It even survivied an explosion using gallons of jet fuel.
Paper wallets and steel wallets are both protected from hardware data degredation, however the ink on the paper can disintegrate or run if it gets wet or too hot.
Steel wallets are also protected from this risk. The OpenDime is basically a cross between a hardware wallet and a steel wallet.
If you're partial to the idea of carrying a paper bitcoin wallet, then OpenDime can be another viable option. Like hardware wallets, open dimes are subject to data degredation over time.
On the other hand, paper wallets use regular paper to reduce the chance of your coins being hacked. Paper wallets keep your public and private keys on a plain sheet of paper, but they can also be modified to include a QR code to transfer data back and forth between your other cold storage devices.
In summary, bitcoin cold storage is an effective way to keep your cryptocurrency from falling into their wrong hands. Even though it can be easy to end up feeling overwhelmed when you consider all of the cold storage options available, there's no reason to limit yourself to just one wallet type.
One of bitcoin's best features is that it's easily divisible, so you can allocate a portion of your holdings to several different cold storage devices at once.
Most cryptocurrency users keep some bitcoin in cold storage and some in a hot wallet to have some funds that are ready to use.
Whichever way you choose to allocate your bitcoin, make sure to keep security at the forefront of your plan. Move your mouse around the screen or enter random letters and numbers into the textbox to add randomness to the wallet creation.
This randomness is called entropy and will help ensure your keys are secure and resistant to brute force cracking. However, there are a number of security concerns to take into consideration:.
Your computer could be infected with malware, which would allow an attacker to see your freshly generated private keys, giving them full access to any funds you then load onto the wallet.
The website itself could also be compromised. You are trusting BitAddress not to view and record the private keys that you generate. Lastly, printers have their own memory where the file containing your private keys could be stored.
For this reason, do not use a shared printer to print your paper wallet. To securely create a paper wallet we will follow the steps outlined above, but take a couple of additional measures to address the security flaws.
This video outlines goes through the process, and each step is listed below for you to follow along. Ideally this would be an airgapped computer that has never seen the internet and never will.
Alternatively, booting off a live installer will avoid most security issues. This guide explains how to create a bootable USB drive off of which you can run Ubuntu, a popular Linux distribution.
The Lightning Network is new and somewhat experimental. It supports transferring bitcoin without having to record each transaction on the blockchain, resulting in faster transactions and lower fees.
Some wallets have the ability to require more than one key to authorize a transaction. This can be used to divide responsibility and control over multiple parties.
Some wallets support SegWit, which uses block chain space more efficiently. This helps reduce fees paid by helping the Bitcoin network scale and sets the foundation for second layer solutions such as the Lightning Network.
