How To Keep Bitcoins Safe

How To Keep Bitcoins Safe

If you are thinking through the process of accruing bitcoins, you may be wondering where to keep them once youve done so. After investing time and resources into the digital asset, can you be sure they are locked safely away for when you want to use them? In truth, bitcoins arent stored anywhere. As a purely digital entity, it is not as if they are held in bank vaults or stuffed under mattresses. They are accessible through Bitcoin addresses, which require a set of digital keys for entry. So, the question of how to securely store bitcoins comes down to the security of these keys. Every Bitcoin address has two keys: a public key and a private key. Bitcoin addresses are derived from public keys, and these Bitcoin addresses are shared. Think of it like sharing your email address with someone: they can send you an email but cant get into your inbox to read your mail. Similarly, nobody can get into a wallet and take bitcoins from it with a public key; it can only be used to send bitcoins. Therefore, it is safe to share. A private key is what allows users to take bitcoins from a wallet or to send them to others, and it is what must be protected to keep a users bitcoins safe. Whoever holds the private key is considered to be the owner of the bitcoins at that address, although technically its possible to possess somebody elses keys without owning the bitcoins they lead to. There are a few different methods that users employ for protecting their private keys. To hold a private key, its possible to encrypt bitcoin wallets with a private password, but this is generally the most basic level of security and one that could potentially be breached by computer hackers or viruses. Others opt to keep their access offline completely. Instead, they hold private keys in disconnected databa Continue reading >>

How To Keep Your Bitcoin Safe And Secure

How To Keep Your Bitcoin Safe And Secure

Owning cryptocurrency isn't quite the Wild West experience it was at the beginning of the decade, but investors still face plenty of instability and risk. The threats aren't just abstract or theoretical; new scams crop up, and old ones resurge, all the time. Whether it's a fake wallet set up to trick users, a phishing attempt to steal private cryptographic keys, or even fake cryptocurrency schemes, there’s something to watch out for at every turn. Cryptocurrencies can feel secure, because they decentralize and often anonymize digital transactions. They also validate everything on public, tamper-resistant blockchains. But those measures don't make cryptocurrencies any less susceptible to the types of simple, time-honored scams grifters have relied on in other venues. Just this week, scams have arisen that divert funds from users' mining rigs to malicious wallets, because victims forgot to change default login credentials. Search engine phishing scams that tout malicious trading sites over legitimate exchanges have also spiked. And a trojan called CryptoShuffler has stolen thousands of dollars by lurking on computers, and spying on Bitcoin wallet addresses that land in copy/paste clipboards. A few simple steps, though, can help cryptocurrency proponents—be it Bitcoin or Monero or anything between—guard against a swath of common attacks. Just as you might keep your cash out of plain sight, or stash your jewelry in a safe deposit box, it pays to put a little effort into how you manage your cryptocurrency. The following won't defend against every conceivable attack on your digital doubloons, but it's a good place to start. A key step to protecting your cryptocurrency is to store anything of significant value in a hardware wallet—a physical device, like a USB drive, Continue reading >>

Blockchain Wallet Id

Blockchain Wallet Id

You are at: Home Questions Blockchain Wallet ID Last updated on January 31st, 2018 at 02:33 pm I have spoken to several people who claim to mine BTC using S9 Antminer. Some are obvious scammers when they ask for complete access to your Blockchain wallet. But when they only ask for the Wallet ID and no other details such as password, is it safe giving them this?

What's A Bitcoin Address? Public Keys, Private Keys, And Addresses Explained

What's A Bitcoin Address? Public Keys, Private Keys, And Addresses Explained

One of the things I get asked all the time is what is a bitcoin address?. Theres the full technical answer for someone who wants to build bitcoin technologies, but theres a lot less to know to bea user of bitcoin nowadays. For example, I bet you didnt know that email runs on a protocol called SMTP (Simple Mail Transfer Protocol) which plays a similar role in email that the bitcoin protocol does in transferring bitcoin (although with some key differences). But if I asked you to fire off an email to [email protected] you could have something ready to send in less than a minute. Sending bitcoin is a similar level of complexity, only you dont need to write a message to send bitcoin. Even Fluffy can send an email with her eyes closed. A lot of people seem to worry about learning the complex mathematics behind the bitcoin protocol before buying and using bitcoin. This might have been true pre-2014 before hoards of startups set out to make bitcoin accessible, but today its simply not the case. So Im going to give you the basic information you need to know to be a userof bitcoin, but not a mathematical expert. So lets get started! A bitcoin address is one of the key concepts that make the currency and the blockchain work. It isnt quite as straightforward to define or explain as an email address. You first need to know about two other parts of bitcoin in order to see how the address fits into the picture: a private key and a public key. The main difference is that you dont use the same address to send bitcoin as you do to receive it. Instead, there are three key terms to know: Private key : a 64 character long code using any combination of the letters A-F and the numbers 1-9. You can see an example of a private key on the image above.This is what you use to send money out of you Continue reading >>

Is It Safe To Reuse Addresses In Ripple?

Is It Safe To Reuse Addresses In Ripple?

I come from the world of Bitcoin and in that ecosystem it is bad practice to reuse addresses because once you spend funds from an address the uncompressed version of your public key becomes available to view in the blockchain and is more vulnerable to attack in principle.

Bitcoin Private Keys: Everything You Need To Know

Bitcoin Private Keys: Everything You Need To Know

Bitcoin Private Keys: Everything You Need To Know By: Sudhir Khatwani In: Bitcoin , Wallets Last Updated: What if you lost all of your bitcoins tomorrow? What would you do? If you dont own your private key, you dont own your bitcoins. Even the most knowledgeable man on Bitcoin says: The private key must remain secret at all times because revealing it to third parties is equivalent to giving them control over the bitcoins secured by that key. The private key must also be backed up and protected from accidental loss, because if its lost it cannot be recovered and the funds secured by it are forever lost, too. In my earlier guide on Bitcoin wallets , I have used two terms extensively-Private Address (or key) and Public Address (or key).These keys are what make Bitcoin the safest and most widely used cryptocurrency . Tounderstand private keys and public keys, let us look at an example. Consider a mailbox where you receive your physical mail. It has a unique and specific number (an address). If someone has to deliver you a letter, he/she must know your house/flat number to deliver it. And as the receiver, you have a private address (or key)to unlock the mailbox and collect your belongings. In real life, do you give your keys to someone unknown? You always keep track of your key and dont jeopardize the contents inside of your mailbox. Similarly, just like your house/flat number, anyone in the Bitcoin world can know your public address(Bitcoin address) to send you bitcoins. And to unlock (spend/send) those bitcoins, you would requireyour private address (or key)for which you need to take full responsibility, just like the keys of the mailbox. I feel that understanding the underlying technical aspect of keys is important so that your remain better informed and educated enough Continue reading >>

Valuable Steps To Make Your Bitcoin Wallet Safe And Secure

Valuable Steps to Make Your Bitcoin Wallet Safe and Secure Bitcoin is one of the oldest and most widely used peer-to-peer payment systems today whose market cap value at the present moment is much more than other cryptocurrencies. Owing to the extensive popularity, many companies, as well as individuals, have already started integrating Bitcoin as a payment system. However, there is always a threat looming over the security of digital wallets. Last year we saw multiple ransomware attacks, including WannaCry which attacked several computer systems worldwide using Microsoft Windows and demanded ransom payment in Bitcoin cryptocurrency. Although the transaction process of Bitcoin is based on blockchain technology, making it extremely difficult to hack the information on cryptocurrency, you still need to meticulously secure your Bitcoin wallet. Lets first discuss what a Bitcoin wallet is. A Bitcoin wallet is a digital wallet where Bitcoins are stored. Obviously, you cannot store your Bitcoins anywhere as they contain a private key or secret number for every Bitcoin address saved in the wallet. There are different types of Bitcoin wallets , such as a software wallet, online wallet, electronic wallet, hardware wallet or paper wallet. But, before we can discuss the various methods and techniques used to secure Bitcoin wallets, its important to throw some light on the major security concerns and threats. To begin with, you must be aware of common threats, such as duping the users through fake cryptocurrencies, the illicit phishing method, secretly knowing the confidential lock PIN code of your phone, attempting to steal the cryptographic keys, etc. The hacker can also hack your Bitcoin wallet by using old password backups. This can be done by creating a recovery program. So, e Continue reading >>

Bitcoin Wallet Definition | Investopedia

A Bitcoin wallet is a software program where Bitcoins are stored. To be technically accurate, Bitcoins are not stored anywhere; there is a private key (secret number) for every Bitcoin address that is saved in the Bitcoin wallet of the person who owns the balance. Bitcoin wallets facilitate sending and receiving Bitcoins and gives ownership of the Bitcoin balance to the user. The Bitcoin wallet comes in many forms; desktop, mobile, web and hardware are the four main types of wallets. A Bitcoin wallet is also referred to as a digital Wallet. Establishing such awallet is an important step in the process of obtaining Bitcoins. Just as Bitcoins are the digital equivalent of cash, a Bitcoin wallet is analogous to a physical wallet. But instead of storing Bitcoins literally, what is stored is a lot of relevant information like the secure private key used to access Bitcoin addresses and carry out transactions. The four main types of wallet are desktop, mobile, web and hardware. Desktop wallets are installed on a desktopcomputer and provide the user with complete control over the wallet. Desktop wallets enablethe user to create a Bitcoin address for sending and receiving the Bitcoins. Theyalso allowthe user to store a private key.A few known desktop wallets are Bitcoin Core, MultiBit, Armory, Hive OS X,Electrum, etc. Mobile wallets overcome the handicap of desktop wallets, as the latter are fixed in one place. Once you run the app on your smartphone, the wallet can carry out the same functions as a desktop wallet, and help you pay directly from your mobile from anywhere. Thus a mobile wallet facilitates in making payments in physical stores by using "touch-to-pay" via NFC scanning a QR code. Bitcoin Wallet, Hive Android and Mycelium Bitcoin Wallet are few of the mobile wallets Continue reading >>

Do not use URL shortening services: always submit the real link. Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy. News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news. Submissions that are mostly about some other cryptocurrency belong elsewhere. For example, /r/CryptoCurrency is a good place to discuss all cryptocurrencies. Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted. Trades should usually not be advertised here. For example, submissions like "Buying 100 BTC" or "Selling my computer for bitcoins" do not belong here. /r/Bitcoin is primarily for news and discussion. Please avoid repetition /r/bitcoin is a subreddit devoted to new information and discussion about Bitcoin and its ecosystem. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system .
