One last thing to keep in mind when it comes to bitcoin wallets is that there is a difference between a wallet and a bank.
Some Bitcoin users view Coinbase as a Bitcoin wallet, but companies like this operate much more like banks. The private keys are what users need to protect to safely use the Bitcoin network without getting robbed.
When you hand someone else control over your private keys, you are essentially making a deposit at that financial institution — much like a deposit at any bank.
Don't store coins on exchanges! Control your own private keys. This is not to say that bitcoin banks are inherently bad.
Companies like Coinbase have done wonders for bringing more users into the ecosystem. Understanding how bitcoin wallets work is an important aspect of safely using this new technology.
Bitcoin is still in its early years of development and wallets will become much more user-friendly in time. Our bitcoins are only safe if the private key was generated securely, remains a secret, and--most importantly--is controlled only by YOU!

As with any unit of value, there is always someone, somewhere that seeks to extract this value for their own ends, whether it be through coercion, social manipulation or brute force.
This guide is intended to provide a broad overview of the best practices for securing your crypto assets. While most of these steps are not mandatory, following them will greatly increase your financial security and peace of mind in the crypto world.
Starting from the ground up, password complexity and re-use are two major pain points that many average users do not consider adequately.
As you can see by this list , average password complexity still leaves a lot to be desired. The less complex your password is, the more susceptible to hack your account is.
If you use the same passwords, or even slight variations of the same passwords across multiple accounts, your chances of compromise are greatly increased.
So what can you do? Fortunately the fix for this is relatively easy. If this seems daunting to you, consider leveraging a password manager such as LastPass or Dashlane that will assist in password generation and storage.
In most cases however, all a hacker needs is access to your emails in order to reset account passwords that may be tied to it. So, if you are like most people and have an email address that has been active for years, with a weak login password, your chances of being hacked are much higher.
Services like ProtonMail and Tutanota are free and offer end to end encryption without sacrificing usability mobile app availability etc.
If you decide to stick with Gmail, consider activating the Advanced Protection Program that Google offers. A virtual private network or VPN is simply a must for everyone today, but especially cryptocurrency users.
As we surf the internet, there are unfrotuantely a lot of eyes on us at all times. One very big set of eyes watching us is our internet service provider or 'ISP'.
They see and hear everything we do on the internet. And they often share that information with third parties. But our ISP and its friends are not the only people watching.
Anyone using the same wifi network that we are using can also see what we are up to online. A VPN solves this problem.
Instead we are communicating to another IP address over an encrypted connection. Then that IP address makes website requests on our behalf and send us back that data.
This helps keep onlookers onto our connection locked out so that only one party knows what we are doing the VPN.
The reason VPNs are important for cryptocurrency users especially is that we use Bitcoin to keep as much data hidden as possible.
However, when we expose our IP address, we might give away that our IP address is connected to someone who owns and uses cryptocurrency, merely because of the websites we visit.
Long story short: everyone should be using a VPN regardless of whethor or not they use Bitcoin. It's for your own safety.
We typically recommend setting up two-factor authentication 2FA for any and every account that offers it, even if the service is not crypto related.
All 2FA does is require a second means of confirmation that you are who you say you are when logging into accounts.
Most typically this is in the form of something you know password and something you own SMS code sent to phone. While SMS is still the most common form of 2FA offered by online services, it is unfortunately the least secure.
The following general use 2FA methods are ranked from most secure to least:. Services like Google Fi offer an alternative to traditional mobile phone contracts that are not only more flexible but also more secure.
With Google Fi, you can prevent any changes from occuring on your account without providing a second authentication factor. This makes it impossible for attackers to hijack your text-messages and take over your accounts.
So if you intend on taking your security serously in this area, Google Fi is the only way to do it if you live in the United States.
Another nice perk of Google Fi is that its easy to change your phone number whenever you want. This feature alone also increases your security since many of our phone numbers have been leaked before and can be used to access other accounts online.
If your leaked phone number is no longer active, you are a little more protected. You only carry small amounts of discretionary spending funds in these wallets as they are more susceptible to loss or theft.
Again, what is more convenient for you is more convenient for a malicious actor as well. Your phone is also susceptible to malware and should not be considered sufficiently safe for storing large amounts of funds.
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.Bitcoin Paper Wallet Abbildung @mszune.nl Zwar heißt es oft, dass die Coins offline gespeichert werden, doch diese.
