Opera Browser Will Protect Users Against Crypto Mining Malware

Published

on

Opera Browser

On January 18, 2018, Opera announced that it will be adding protection on its mobile browsers against cryptocurrency mining scripts. With crypto mining malware being on the rise, the company expects that the move will help protect hundreds of millions of smartphone users who use the Opera Mini browser. The announcement follows the company’s recent move to add the protection for its desktop users, making them the first in the internet browser industry to do so.

2017 will be remembered as the year that bitcoin went mainstream and with this, also came the rise of cryptocurrency mining malware.

While most miners make use of their computing power to mine for new coins, there is now a new trend of websites mining cryptocurrencies using the computing power of their users without their knowledge. It is estimated that the phenomenon affects more than one billion people globally resulting in their devices becoming slow, running warm, and weakening batteries.

“When you browse the web, there are no visual clues that your device is exposed to mining. A single webpage you visit can take up to 4.5 hours of your battery time if you keep the tab open. This often turns out to be just the battery time you needed to use a ride-hailing app or check the map to get home,” said Jan Standal, Opera’s VP for Product Marketing.

How it Works

There is a higher need now for extra protection against cryptocurrency mining scripts as there are over three million websites that are exposed to cryptojacking, according to reports. Opera’s move is meant to ensure that end users have their smartphones operating efficiently with enough battery life for the things they really need.

By default, the new anti-cryptocurrency mining feature gets activated once the ad blocker is triggered on Opera for Android and Opera Mini. The ad blocker can be activated in ‘Settings’ after which all mining scripts written on any webpage’s code will be detected and stopped.

Tests conducted by the developers at Opera of its browsers on Samsung Galaxy S8 and HTC One smartphones proved that cryptocurrency mining scripts increase a smartphone’s CPU usage by 100 percent. This leads to overheating of phones as well as increased battery drainage. The test also proved that activating the ad blocker on Opera for Android enabled phones to recover their CPU usage.

The test by Opera sheds light on the increase of digital currency malware and the need for people to protect themselves. Smartphone users can download Opera for Android and Opera Mini on Google Play.

South African Cryptocurrency Exchange Introduces Tether (USDT) Trading

Published

In a move to attract foreign investors and drive down bitcoin’s price in South Africa, AltCoinTrader, a Johannesburg-based cryptocurrency exchange has introduced Tether (USDT) trading.

BTC/USDT on AltCoinTrader

AltCoinTrader introduced the trading pair BTC/USDT in July. Tether (USDT) is a cryptographic asset that is backed by US dollars and thus acts as the equivalent of “cash” in the cryptocurrency markets. USDT is a particularly popular asset during a bear market as it can act as a safe having when other cryptocurrencies are losing value. Moreover, USDT allows investors to hold de facto dollars but in digital format, which adds liquidity to the markets.

Richard de Sousa, a partner at AltCoinTrader, said:

“The trading pair is quite important because it allows people to buy bitcoin without using rands.”

Due to the dynamics of supply and demand, bitcoin tends to trade at a six to seven percent premium in South Africa. The exchange is expecting the valuation gap to narrow over time by giving opening the market to foreign investors through its USDT introduction.

USDT Trading May Drive Down High BTC Prices in South Africa

South Africa has very tight currency regulations, which make bringing money into the country and, even more so, taking money out of the country very difficult. This is also felt by bitcoin investors who want to purchase bitcoin on South African exchanges.

Thanks to the USDT option, however, non-South African investors can now also take part in BTC trading on South African exchanges, which should lead to a decline of the high premium that South Africans currently pay for buying bitcoin due to the arbitrage opportunities that are now available to international cryptocurrency investors.

AltCoinTrader’s De Sousa added that although it would take a while to catch on, investors who will see the arbitrage opportunities and take them could profit. This, in turn, should benefit everyone, including “the man in the street”, because the price of bitcoin in South Africa would drop closer to international prices.

We are also working on an Airdrop turnkey table which will allow anyone to send us a token.  This will allow us to immediately list it on our database so that the community get find all the airdrops in once place.

“Bitcoin Gold Wants to Bring Mining Back to the People as per Satoshi’s Original Vision” – An Interview with BTG’s Community Manager for Africa

Published

on

Bitcoin Gold Africa

Bitcoin Africa had the pleasure to interview Richard Boappiah Asamoah, Bitcoin Gold’s community manager for Africa, via Telegram to find out more about Bitcoin Gold’s efforts on the continent.

Bitcoin Gold (BTG) was created in late 2017 as a hard fork of bitcoin (BTC) with the aim to “make bitcoin decentralised again” through the enablement of GPU mining. The digital currency has a market capitalisation of over $400 million and one BTG coin is currently worth around $25.

What is bitcoin gold’s plan for Africa?

Bitcoin Gold Africa

There are several initiatives underways. One that I can publicly share at this point is e-commerce. BTG has grown fond of the idea of expanding the current state of the African economy through the promotion of digital payments by establishing BTGpay. Basically, payments with bitcoin gold.

We also plan on promoting blockchain-related programs through local partnerships and want to expand our ambassador program. BTG plans to support this by providing sponsored meetups and local development proposals led by various appointed ambassadors across Africa. Hackathons, scholarships for students, developer conferences and other meetup events are on our list for this.

Is the focus of bitcoin gold on creating wealth for its users through GPU mining or does the BTG community aim for its currency to eventually replace bitcoin?

Bitcoin gold is a friendly fork and has no intention of replacing bitcoin but instead aims to develop itself in its own way to bring mining back to the people as per Satoshi’s original vision.

How do you tell bitcoin gold’s story to the masses who are just now getting accustomed to bitcoin?

We inform people that bitcoin gold is a fork of bitcoin, which means that bitcoin gold’s developers took the code base of bitcoin and developed it in more friendly direction by making mining decentralised again.

Why bitcoin gold? Like all other cryptocurrencies, BTG is built on a technology known as the blockchain, which allows transparency for day-day transactions as well as providing us with low fee digital payments and a secure way of paying and getting paid without any geological restriction. Also, bitcoin gold is planning to implement the BTG lighting network, which will tackle issues of blockchain scalability providing millions of transactions within seconds.

What countries in Africa are your efforts primarily focused on?

At the start of the ambassador program, we plan to target crypto hotspots who are well versed in digital payments. This includes the likes of Kenya, Ghana, Nigeria, South Africa, Uganda. Subsequently, we plan on conquering the continent as a whole.

The ambassador program is scheduled to start soon.

How can Africans interested in BTG get involved in the bitcoin gold Africa community?

Africans interested in joining the bitcoin gold community can get involved by linking up with us on Telegram, on Twitter, and in the bitcoin gold forum.
