1. What is Blockchain Wallet?

Blockchain Wallet is a web wallet for storing two most popular coins: Bitcoin and Ethereum. If desired, it is possible to install an app for iOs and Android, only the web version is fully functional.

It’s the most popular cryptocurrency wallet in the world, as of the time of writing of this article (the middle of October, 2018), more than 25 million accounts have been already registered. It’s different due to clear interface, and the high level of safety. Certainly, these factors are attractive for new users.

The peculiarities of Blockchain Wallet

  • The service cooperates with a lot of cryptocurrency exchanges, that’s why there is a possibility to buy and exchange coins from interface wallet.
  • It is an opportunity to edit commission for making transactions.
  • The high degree of safety of the online wallet. There is a special “safe centre”, where safety measures are taken (installing phone’s confirmation, making backup, changing password, etc).

2.  The procedure of setting up a wallet

For creation of a new Blockchain wallet you need a valid email and two minutes of free time.

  • First click https://www.blockchain.com/wallet and press “Create your own wallet”.
  • Write your mail and think of and remember a password (and a password hint) and just follow instructions.
  • After login, press the button “The inquire”
  • Point what currency you are interested in: BTC or ETH.
  • After choosing your own wallet, indicator will be generated, which will represent a great amount of numbers and letters without gaps.

A wallet supports two coins, it’s important to be attentive and send BTC on bitcoin  and ETH on ethereum wallets. Since it is impossible to cancel a transaction in blockchain, sending coins on wrong wallet leads to losing money.

3. The level of safety

The safety is a very important factor which it is necessary to pay attention to when choosing. Blockchain Wallet can offer three levels of safety.

  1. Initial. It requires the confirmation through mail, where the wallet will send confirmation codes for making transaction or log in. If it discovers any suspicious activity, the service will inform you with a letter. The initial safety level implies pass-phrase which makes it possible to recover the password. If you lose or forget the password from your wallet, you will recover it only with a help of pass-phrase. Without a passphrase even customer support specialists can’t help you, because they don’t have such possibility.
  2.  Middle. It requires two-factor authentication through mobile phone. At every new attempt to log in the service will send a confirmation code on your mobile phone.
  3. Maximal. It is an installation of an additional protection from log in users which use a special anonymizer Tor. It is often used by hackers to get anonymity.

Don’t forget that Blockchain Wallet is a web-wallet, so that we can’t speak about full protection. Since private keys of the wallet are kept on companies’ services, theoretically they can be stolen and all money can be stolen too. A probability of it isn’t so great, but anyway it isn’t a good idea to store all money on this wallet.

4. The cons of Blockchain Wallet

  • There aren’t so many weaknesses in this product, but they are worth mentioning.
  • As it was said below, online wallets aren’t as safe as hardware, which are more suitable for a long term assets saving.
  • Only BTC and ETH are supported
  • The procedure of verification may seem a little bit difficult for new users but it’s only the first impression.

5.  Conclusion

Nowadays Blockchain Wallet is the most popular in the world for storing cryptocurrency. The interface of this service is very convenient and clear even for inexperienced users. As for a web solution, the service has a high safety level. Blockchain Wallet is an ideal solution for storing and transferring cryptocurrency assets.

BitPay Transactions Surpasses $1B in 2018, B2B Payments Records 225% Increase

BitPay is a US-based bitcoin payment provider which has recently announced its financial results of the past year. The company has processed over $1 billion in transactions alone. Moreover, its B2B payments record 225% increase in compare to 2017.

The main reason of such a lift-off is that Bitpay added a lot of new clients, like Dish Networks, HackerOne, and the State of Ohio, as well as many other law firms, data center providers, and IT vendors.

The CEO of BitPay, Stephen Pair, commented on this development:

“BitPay’s B2B business continues to grow rapidly as our solution is cheaper and quicker than a bank wire from most regions of the world. To process over a $1 Billion for the second year in a row despite Bitcoin’s large price drop shows that Bitcoin is being used to solve real pain points around the world.”

BitPay mostly supports Bitcoin transactions, however, it also supports payments with Bitcoin Cash, Gemini, and Paxos. During that year a lot of companies had to lay off their employees due to the market situation, yet, Bitpay conversely increased its manpower by 78 percent in the past year.

In addition, BitPay is attractive to the investors, in 2018, it raised $40 million in Series B funding round taking the total raised capital to $70 million.

New Useful Gadget or Promotional Trick: What Is the WT2 Plus Earphone Translator?

A language barrier is the main cause of disagreements and the reason why people of different nationalities cannot fully communicate. But, besides, a language barrier complicates the lives of many travel lovers. Soon this problem will fall into oblivion, as its solution was suggested by Timekettle company in the form of a new gadget WT2 Plus. Now this device is presented at the International Consumer Electronics Show CES-2019 in Las Vegas.

What is WT2 Plus?

This is a wireless earphone translator, which will become an integral gadget when traveling to foreign countries. The novelty caused a huge interest and made many people wonder: “What is the price of WT2 Plus?”. You can breathe a sigh of relief, because the answer is already there! The cost of WT2 Plus is $ 219.

Source: http://www.timekettle.co/

How does WT2 Plus work?

The earphones support Android and iOS operating platforms. They connect with a mobile device via Bluetooth using the application that allows users to set a language. At the moment, the application supports 20 languages, but in the near future the developers will add another 15.

The feature of the application for WT2 Plus is recognition of various accents. For example, the application supports 5 accents of English, including Australian English.

Direct use of portable earphones occurs as follows: in order both interlocutors can talk and hear each other, each puts one earphone from the kit on. When talking, the earphones transmit the sound to the smartphone for translation and transferring the translation back to the earphones. The delay in processing and transferring sound takes only 3-5 seconds, depending on a sentence size.

Even though the manufacturer emphasized the possibility of real-time translation as its main advantage, in fact the device is capable of translating only short phrases, the duration of which do not exceed 15 seconds. For example, the gadget can not be used for continuous translation of a film in a foreign language.

Regardless of the headphones’ being wireless, they will not catch environing phrases and translate them due to the built-in “Touch” mode, which allows you to use WT2 Plus in crowded places.

The earphones themselves are stored in a pocket-case that resembles Apple’s AirPods case. The earphones are charged from the case. Each earphone has a 110 mA battery, and the case battery capacity is 320 mA. Full charge of the earphones takes 90 minutes. The case works for two weeks without recharging, it is enough for two recharges of each earphone.

The manufacturer plans to increase the accuracy of the WT2 Plus translation to 95%. The translation requires access to the Internet, since it is carried out through Google and Microsoft cloud servers.

“51% Attack” Hit Ethereum Classic: A Full Analysis Of The Process

As we have reported earlier, Ethereum Classic was hit by 51% attack, it means that hackers obtained more than 50% of network’s mining hashrate.

A Malicious “51% Attack” Hit Ethereum Classic, The Loss Allegedly Accounts For $460 000

Slowmist, Chinese-based blockchain journal, has released a full report on the attack. The earliest hit occured on January 5, the culprit hacked some exchanges, like Bitrue, Coinbase, Gate.io, however, this was noticed only two days later.

The first action was a transfer of more than 5000 ETC from Binance to the criminal’s address 0x24fdd25367e4a7ae25eef779652d5f1b336e31da. This amount of coins moved to a mining node, that created block 7254355. After that, the hacker deposited 4000 ETC to Bitrue exchange in block 7254430, yet, this transaction vanished from the Ethereum Classic chain. Another 9000 ETC was stolen in the same way. The Bitrue address 0x2c9a81a120d11a4c2db041d4ec377a4c6c401e69 no longer exists, and the official history is clear. Though, Bitrue managed to save some records:

The scheme of the hacker attack is simple:

  • make a deposit;
  • withdraw to a safe address;
  • to double coins – just move the coins to other addresses.

One of the biggests victims is Coinbase exchange. It was estimated that the loss from the attack accounts for $1 million. The above-mentioned report also provides the information about two attacker addresses which were blackmailed by Coinbase later. They are:

– 0x090a4a238db45d9348cb89a356ca5aba89c75256
0x07ebd5b21636f089311b1ae720e3c7df026dfd72

In Twitter, one of users (nickname: @OGBTC) claimed that he knew the culprit personally.

https://twitter.com/OGBTC/status/1082559086070136832

Another user (nickname: @sebseb7) indicated that it was he who knew the hacker.

The “51% Attack” is over for now. All we can do is to estimate the losses and to take measures so that it will not happen again.

The report also stated:

“[W]e recommend that all digital asset services platform block transfers from the above malicious wallet addresses. And strengthen the risk control, maintain a high degree of attention, and be alert to double spend attacks that may erupt at any time.”

How to Get Bitcoin And How Profitable is Mining in 2019

Appearance of Bitcoin has marked the beginning of a new era in development and dissemination of money. 2018 became a crucial point for cryptocurrencies. In this article we will talk more about Bitcoin mining, find out what is needed and how to earn from it.

1. What is Bitcoin mining?

BTC mining is carried out with the help of specialized computer equipment, so-called Bitcoin farms. In order to open a new block, the miners resolve complex mathematical problems, for which the network rewards them with X number of coins.

Bitcoin algorithm is designed in such way, that every 210 thousand blocks the reward decreases exactly by twice. At the very beginning, miners received 50 coins for each new block, then this number was reduced to 25, and now this value is 12.5 BTC.

2. What are the ways to get Bitcoins?

Bitcoin is the most popular cryptocurrency in the world, many people would like to become its lucky owner. Here are some ways to do it:

– Bitcoin faucets. This is an absolutely free method to get coins. It lies in performing various simple tasks, such as decoding and entering captchas, clicks on advertising links, browsing advertisers` websites, etc. This work is absolutely simple, but it requires  patience. We want to remind you, that reward for such work is purely tokenistic and it is not possible to earn decent money from Bitcoin faucets.

– Mining. This method means investment into equipment. It can be completely different: you can organize home mining on graphics cards spending 2-3 thousand US dollars on it, or you can build a huge data center by investing hundreds of millions of US dollars into this enterprise. Thus the income should be directly proportional to the initial investment. Unfortunately, today cryptocurrency is so volatile that it is impossible to calculate how much profit Bitcoin mining will bring in 2019.

– Salary in crypto. Nowadays, the fact of getting salary in cryptocurrency is no longer supernatural. Yes, it is still uncommon, but it is far from single instance.

– Purchase. The most obvious way to get cryptocurrency is to purchase it. Nowadays, you can buy Bitcoin using a large number of services (exchanges, currency exchange offices, individuals, etc.).

3. What is needed in order to start BTC home mining ?

In general, this is rather a broad theme, but in this article we will only briefly run through the main points, without which home mining is impossible. So you need to:

  1. Buy equipment for mining (graphic cards or ASIC miners).
  2. Create a Bitcoin wallet. Without this it will be impossible to get coins.
  3. Select a mining pool. Nowadays the hash rate (total computing power of all the miners) of Bitcoin network is really huge, that is why the algorithm constantly increases its overall complexity. This is why it will be very difficult for one miner to open a new block even with sufficiently powerful equipment.
  4. Install a special software for mining.
  5. Follow the process and, if necessary, repair or replace the components.

You should also remember that mining equipment (especially ASIC-miners) make a noise and heat up while working, therefore installment of farms in a residential house is not a good idea.

4. What is cloud mining?

There is another way to start mining Bitcoins. This is a cloud mining. It does not involve physical contact of person with equipment. A user buys a certain amount of computing power at a large data center and immediately starts to get income from it. So, how is it better to mine Bitcoin, on your own or using cloud? Everyone will find his own answer. Definitely, profit of home mining will be higher, but cloud mining will ease your pain associated with farm maintenance. Someone is willing to pay for his or her comfort, but another one would prefer to do everything by independently, therefore, everyone decides on one’s own.

5. Which video adapters work best for Bitcoin mining?

Each particular video adapter has its own payback period, which directly depends on what is happening on the cryptocurrency market. 2019 has just started, so here is the list of the most cost-effective video adapters for BTC mining in 2018:

  • NVIDIA GTX 1080 TI.
  • NVIDIA GTX 1070 TI.
  • NVIDIA GTX 1070.
  • RADEON VEGA FRONTIER EDITION.
  • RADEON RX VEGA 56.
  • RADEON MINING RX 470.
  • NVIDIA P106-100 (GEFORCE GTX 1060).

6. How to calculate Bitcoin mining correctly?

Bitcoin rate is very volatile, network hash rate is also unstable, so, it is almost impossible to calculate exactly the mining profit. But there are convenient calculators which will help you to find out at least approximate numbers.

7. What does BTC rate depend on and what will happen next?

Bitcoin price varies in the trading range of USD 4000.00. Bitcoin emission is limited and it amounts to 21 million coins. Over 17 million ones have already been mined. But it is necessary to recall a double decrease in the remuneration for a found block, which occurs every 4 years. It is easy to calculate that over the next 30 years, more than 99% of all coins will be mined, and the remaining 1% will be mined over the next 100 years.

According to the laws of economics, this feature makes Bitcoin a very valuable and, most importantly, a limited resource. Now Bitcoin capitalization is about 70 billion US dollars, and it is absolutely a wasted number from the world scale perspective. Many market experts predict a great future for this coin, for example, John McAfee believes that 1 Bitcoin by December 2020 will be USD 1,000,000.00.

If to take a look at Bitcoin chart for the entire history, one can see approximately the same picture of what is happening: rapid growth, prolonged correction, stagnation after which the cycle repeats. Moreover, every time during the correction, the media “buries” Bitcoin, and the coin after some time again renews its previous records.

8. Conclusion

Bitcoin mining, as of the beginning of 2019, is not a very profit-making enterprise without major initial investment. Bitcoin mining should be considered more like an investment for the future, when BTC becomes a very scarce asset and its value can literally skyrocket. Well, we cannot do anything but wait and actively monitor the developments.

GMO Will Keep On Mining Bitcoins at a Different Location

One of the world’s largest IT companies, Japan-based GMO has published its monthly report regarding its mining activities and the profits coming from them.

We remind you:

Japanese GMO Releases a Monthly Update: What Has Changed As For Mining?

Based on the December’s document, the revenue from mining cryptocurrency has dropped down  significantly which implies that immediate measures must be taken.

One of the biggest pitfalls of mining is the amount of electricity consumed and its high price. Thus, GMO made a decision to relocate its main mining center into a different area, where electricity will cost way less.

We will relocate the mining center to a region that will allow us to secure less expensive power supply,” reads the report.

Moreover, the company refuted all the rumors regarding its alleged plans of giving up mining completely. Since 2017, when GMO first engaged into mining, it has earned massive profits and still sees potential in crypto.

As we may see in the statistical data, the mining reward for Bitcoin increased a lot in the last month of December, whereas Bitcoin Cash suffered a hard fall. But the crash of the crypto market and Bitcoin in particular could not be controlled by GMO and affected its business quite badly, making it “move houses”.
