 Prevent your bitcoin account from hackers

Sometimes you have to face different issues with your funds. They may be snatched or hacked by someone. Whereas, bitcoin is a digital currency and addresses may be hacked by someone. To prevent from hacker, bitcoin must be kept behind multiple layers of security. In this article, we will discuss the ideas, how you can prevent your accounts as well as your addresses.

The most important feature of the bitcoin is transactions aren’t reversible. This means that once you do transactions either receive or send coins, they don’t have revers back feature. But, if your bitcoin account gets hacked then also you are not able to get back them.

Make sure first while you are dealing with someone via bitcoin technology. That person should be reliable and well-reputed. These precautions are necessary, but this is incomplete security.

To secure your accounts some basic personal checks, which may reduce the chances of your account being hacked or compromised. They are;

  1. Secure your email account
  2. Secure your technology related social media accounts
  3. For all the online accounts, use unique and strong password
  4. Enabling two-factor authentication

The Main Issue:

Someone breaks into an unlocked house and take precious diamond jewelry away. This is not jeweler’s fault. You were not able to keep your things secure from a robber. Same with the email accounts. People says that their accounts got hacked. The reason is they don’t completely put security to their accounts.

If a hacker has access to your email account, he will see the history of websites you log in. In addition, will visit the sites one by one and ask to reset the new password. Once the password gets restart, you will easily cut off from your account.

Secure Your Email Accounts:

Following are some terms by which you can secure your account.

  • use the strong and unique password
  • keep eye on login activity
  • review and remove email auto forwarder
  • the review linked accounts
  • 2-factor authentication

Use Strong And Unique Password:

Now, its technology era and you have to follow its rules and regulations. When you make an account on social media you have to use unique and strong password consisting of letters, words or capitals. In addition, especially in a case of bitcoin. You have to make sure that your password is strong, tricky and unique.

Keep Eye On Login Activity:

well-reputed email provider websites allow you to see which locations and devices recently accessed your email account. If your email account is open on both laptop and mobile, sites will show you double login sessions. And, you don’t recognize your login session, immediately sign out of all other sessions.

Review And Remove Email Auto Forwarder:

Most of the email sites provide a feature where email can be forward to different addresses automatically. If you monthly received the invoice from telephone company then your spouse or housemate will receive the copy of the same email. Which is more secure for your email accounts.

Prevent your bitcoin account from hackers

Here, the issue is, if the hacker got access to your accounts in past. Possibly they have auto-forward setup. Accordingly, the one for sensitive emails to be forwarded to them. These saved emails can be used against you.

Review Linked Accounts:

Review links accounts may be used for good and bad both purposes. We humans like new changes in our routine life. The problem is when we don’t want to log-in and after switching to new one, emails still send to the old addresses.

In that sense, you simply link to two accounts. And, you also have the accesses to both accounts, you can log into the new one, link the old one and all emails sent to the old account will still arrive in your new account. You can send email from a new account by using the other addresses. while you are doing small business it is useful for you. Where you can receive, and send the email to the same inbox. But, the problem is still the same. If your account gets hacked and hacker receives and send the emails same as you. In that scenario, you don’t have another option. So, keep your accounts secure by adopting different ways of security.

2-Factor Authentication:

Two factors authentication needs two things to get access to your email account.

  • your password
  • your mobile phone

If two-factor authentications are enabled, no one can get access to your email account.

Secure Your Technology Related Social Media Accounts:

People are friendly with the social media they do the same with email accounts. They won’t need a new password or new email account.

 

 

Social Media Accounts

For all the online accounts, use unique and strong password

your password should be strong and unique. The reason behind is,

Why Should Password Be Strong And Unique?

we already discuss that password of your accounts should be strong. It is simple, that your login different accounts with same and simple password. You are leaving your account open to hacking.

Especially, when you are treating with bitcoin wallet addresses. you need more security for your funds. Hundreds of time we log in with hundreds of the sites. Which may have an option of encrypting. So, it’s totally up to you to choose a suitable and reliable site for your transactions.

It very simple for the hackers to hack bitcoin wallet. So, use password management tool for a strong and unique password. It will help you surely.

Enabling Two-Factor Authentication:

Prevent your bitcoin account from hackers

One of the best and free ways to secure your accounts is two-factor authentication with the time period of two minutes only. 2F-authentication create an extra layer to any account by requiring two things. Are, • something you know which is your password. And,

  • something you have is your device

Now, many sites support two-factor authentications including google, Luno, and Facebook etc. It is possible that you already receive a message with the one-time pin for certain transactions from your bank or credit card provider. These are the type of 2F authentication.

How To Enable 2FA?

  • Add a new account
  • Scan QR code as shown by site
  • Save that account

Luno will send you six-digit code,

  • Type it into your 2FA app
  • Click enable

Above code changes in every 20-30 seconds. Your device and Luno now connected. As a result, if someone wants to get access your account, he/she have to get Luno password first.

Monero Security – 3 Main Techniques Behind Monero Anonymity Explained

Want create site? Find Free WordPress Themes and plugins.

Along with being accessible through networks such as Tor and I2P, Monero implements various cryptography techniques to unlock an extensive level of security and privacy:

1. Untraceable Stealth Address

As we all know, reusing the same address for bitcoin transactions is a common privacy issue of Bitcoin. Receiving or sending multiple transactions to the same address can allow anyone who knows your address to track its activity. Thus, bitcoin is not a tool that should be used on the darknet, especially for privacy purposes.

On the other hand, Monero has no such privacy concerns. Monero’s blockchain is secured in such a way that only the sender and receiver are able to identify the destination address. Only a unique cryptographic hash is provided, to each and every transaction that can be decoded by just the send or receiver to disclose the real address. These encrypted addresses are called “stealth addresses.”

2. Unique Separated Transaction Units

When you send XMR to any address, it arrives as several separate payment units. Basically, each unit would appear on the Monero blockchain as being transferred to its appointed and distinct stealth address. This process is applied to the sender as well as the miners when any fees are paid to them. This makes tracking of any transactions far more complicated.

3. Undetectable Ring Signature Payments

Ring Signatures is another technique that adds up to the cryptographic system behind Monero’s blockchain.

Just to be clear, similar to Bitcoin, Monero also consists of a public and private key in order to engage in buying or selling of XMR.

For example, if you are to send 18 XMR to a shop, the XMR get sub-divided into 10,5 and 3 XMR streams, these flow into distinct Monero addresses of the ship.  The private key that authorizes any 10, 5 and 3 streams sent across the network, becomes a possible signatory to the transaction. The number of possible signatories is dependent on the “mixing depth” you set. As your transaction splits into units, ring signatures guarantee that transactions can’t be stalked back to any system’s IP address.

In the end, it’s almost impossible to track or identify Monero users

These 3 techniques provide maximum privacy and prevention from roaming trackers. Monero’s code ensures the anonymity of every user and leaves barely any possibility of a linkage to take place.

Crypto Exchange EtherDelta Gets Hacked – Loses Coins Worth Millions

Want create site? Find Free WordPress Themes and plugins.

A renowned crypto exchange EtherDelta got its DNS server breached by an attacker on Wednesday, allowing the hacker to redirect millions of users to a malicious website.

The announcement of the hacking was made in a series of tweets where EtherDelta warned users that a hacker had temporarily hacked their DNS server and was redirecting users to a malicious version of the site.

Being a decentralized exchange, EtherData comes under the control of Smart Contracts, meaning that it doesn’t provide the third-party control of user funds. However, the exchange does allow users to import private keys to the exchange itself.

As a result of this attack, the hacker was able to steal private keys from users who unwittingly imported their private keys into the imposter website.

The data obtained has revealed that the hacker stole around 308 ether – worth around $250,000 at the time of writing.

EtherDelta said that clients who got to the exchange using either MetaMask or a hardware wallet are “totally sheltered” from the phishing attack. The organization included that funds from clients who never imported their key on the malicious site “should be safe,” but brokers might need to consider moving their assets to another wallet address as a safety effort — and reconsider their choice to import their private keys directly into a site.

The Risks Associated With Crypto Exchanges:

The attack came days after South Korean exchange Youbit revealed that it lost 17 percent of its assets as the aftereffect of a hack — the second the organization had faced this year — compelling its administrator, Yaipan, to declare bankruptcy.

Like Youbit, EtherDelta was a small exchange. CoinMarketCap reports that it processed just around $7 million of volume during the previous 24 hours, a figure that is, to some degree, lower-than-normal because of the breach. However, the exchange was well known among ERC20 token merchants, as it was one of the first exchanges to support tokens derived from lower profile ICOs (Initial Coin Offerings).

Neither of these hacks will prompt a huge disturbance in the worldwide digital currency markets, but each exhibits the risks related to using crypto exchanges.

Bitcoin Price accelerates beyond $2000

Want create site? Find Free WordPress Themes and plugins.

US markets are celebrating as Bitcoin price soars above $2000 for the first time in history. Bitcoin’s price has surged more than 100% this year and nearly 125% since hitting an annual low of $891.51 in late March. Due to the price recently hitting new heights, the price appreciation will increase dramatically as well.

 

Bitcoin Price accelerates

 

Growing trader interest

The advantage of such sharp price gains is the rising interest of traders as measured by trading volume at major exchanges. Both Kraken and Poloniex had reportedly announced that they were experiencing surging bitcoin transaction activity.

Bitcoin Price accelerates

 

 

A number of factors have been driving the rally:

  • Trading volumes of Japanese yen and Korean won have escalated and account for around 48.6 percent of trading, according to stats from website CryptoCompare. That’s thanks to a recently passed law that allowed retailers in Japan to begin accepting Bitcoin as a legal currency. Since then, Japan has been a big driver of bitcoin trade.
  • Bitcoin has acted as a safe option, in the past, for investors that worry about political instability and the performance of other asset classes.
  • A debate within the bitcoin community about the future of the technology behind Bitcoin known as the blockchain has been taking place. At the moment, Bitcoin transactions are taking an unusually long time to process and come with high transaction fees. There was fear at one point this could lead to the merging of two different cryptocurrencies but those doubts have largely subsided with an alternative, more acceptable option being put forward.

All these factors add up to the rise in Bitcoin’s value in the shortest of time. According to CoinDesk, several billion US dollars have flowed into bitcoin last week, bringing its market value to more than $37 billion. In the end, as Bitcoin grows to gain more popularity and accessibility around the globe, its price will continue to soar as high as it can go.

Bitcoin Is Poised To Hit $100,000 – Says The Predictor Of Q4 Rally

Want create site? Find Free WordPress Themes and plugins.

A Hong Kong merchant who correctly predicted bitcoin value’s dramatic year-end rise trusts that its rally is a long way from being done.

Dave Chapman, managing director of digital currency exchanging firm Octagon Strategy, told that numerous investigators laughed at him when he anticipated the bitcoin cost would dramatically increase in the final quarter and reach $10,000 before the finish of the year.

Main Story:

“I was cited back in August when bitcoin was trading at around $4,000 that we would have a five-figure headline before the current year’s over,” he said. “I think many individuals thought I was insane, many individuals laughed at me, but that is OK.”

 

However, regardless of condescending looks, the bitcoin cost has met — and surpassed — Chapman’s expectation. At the time of writing this article, bitcoin was trading at $16,615, a 20 percent rally boosted by the dispatch of CBOE’s bitcoin futures contracts.

The bears credit this development to a speculative frenzy, and Chapman admits that he is somewhat worried about the market’s current “warmth”. However, he denies that bitcoin’s value is purely from speculation.

 

“Bitcoin permits the quick exchange of significant worth from one individual on the planet to some other individual on the planet, and it does that without a middleman. That is its value,” he said. “If you take a look at bitcoin and its impact financial industry, it’s clearly not that crazy to believe that bitcoin could be a greatly enormous disruptor to finance.”

 

Chapman said that the launch of bitcoin subsidiaries is an indication that digital currency is “growing up,” and he included that he would not be shocked if the bitcoin cost comes to $100,000 before the finish of 2018. Nevertheless, he warned that winding up too focused on digital currency costs will make individuals lose sight of the revolutionary aspects of the crypto technology.

 

“The cost to me is presumably the most uninteresting part about bitcoin. I’m more excited about the applications and more amped up for what this means for individuals who lack access to financial inclusion,” Chapman finished up. “If we concentrate on the cost, we’re forgetting about the bigger picture.”
