What is Cryptocurrency and how to buy them?

World is evolving rapidly and so is the mode of exchange. Each country has their own currency but when trade is to be done across borders, then there is no common currency and so transaction has to be leveraged upon Dollars which is again the currency of US.

Digital technologies have virtually connected the world via internet. Blockchain is one such technology through which decentralized digital currency or virtual currency has came into existence. These virtual currencies are nothing but timestamp based cryptographic identities generated using very distinct algorithm. These algorithms are very secure and keeps detailed traces of each transaction within Blockchain ledgers. This has made economists and technology experts rely on virtual currencies generated by Blockchain technology. 

As these virtual currencies are generated digitally using cryptographic algorithms, they are also known as Cryptocurrency.

Bitcoin is the first cryptocurrency that came into existence from 2009. After its worldwide acceptance various other virtual currencies were launched with little enhancement over bitcoin. Till the end of year 2017, there were more than 100 such virtual currencies in existence out of which few popular ones are Ethereum, Litecoin, Ripple, IOTA and BitcoinPower.

Each physical currency has an acronym: USD for dollar, EUR for euro, INR for rupees, etc. Similarly acronym is also specific for each virtual currency: BTC for bitcoin, ETH for ethereum, LTC for litecoin, XRP for ripple, etc.

Similar to stock exchange available for stock market, cryptocurrency exchange websites also exist. Through these cryptocurrency exchange you can buy, sell or exchange cryptocurrencies with other digital currencies or traditional currency like dollar or euro. Coinbase, Kraken and Bitstamp are the most popular cryptocurrency exchange websites where you can create account and start trading.

Even though virtual currencies are not yet made legal by many countries, but multinational enterprises have started upgrading their applications to accept cryptocurrencies as a mode of exchange. World giants like US, Japan and Canada have started using cryptocurrencies since long and other countries are also working on this digital revolution to amend their taxation policy.

India has not yet legalized the cryptocurrency transactions as its impact on economy is still being analyzed by experts and economists. Its government has given clear indication that they are amending their taxation policies to restrict unauthorized inflow/outflow of funds so that such transactions can be legalized.

Though it is not necessary to start doing transactions in cryptocurrencies on immediate basis, but it is better to keep account ready to operate it whenever opportunity grows. Here is a list of few exchanges where cryptocurrencies can be bought in Indian rupees:

• Koinex
• Ethx
• Sragy
• BuyUCoin

These are two mobile apps that can also be kept handy:

• Zebpay
• UnoCoin

Open source, peer-to-peer, community driven decentralised cryptocurrencies are also available that allow people to store and invest their wealth in a non-government controlled currency, and even earn a substantial interest on investment. This means anyone holding such currencies in their wallet will receive interest on their balance for helping them maintain security of the network.

Google enables default ad-blocker within Chrome

The use of the internet is flourishing each day as laptop and mobile users are increasing exponentially. This has led to an increase in the digital marketing industry business.

Google has plunged into digital marketing for a long time and also earns a lot of revenue from Adsense. With the help of ads banners, the revenue is generated by either CPC (Cost Per Click) or CPM (Cost Per Impression).

More than 70% of mobile devices operate on Android having Chrome as the default browser that very well supports ads banner. However, this support is so extensive that there is no facility to restrict such ads. Few Chrome extensions are available that can be used as ad-blocker up to some extent.

Some websites are loaded with unpleasant ads that make the browsing experience uncomfortable. To overcome this concern Google has upgraded Chrome to restrict ads while surfing. This decision of Google has created a storm in the digital marketing industry as their business is on the verge of getting ruined, however, Chrome users have greeted this decision with open hands.

This upgrade of the ads-free version of Chrome was rolled-out on February 15, 2018. This version enables a default adblocker within Chrome which will block most of the intrusive ads including full-page ads, flashing animated ads and auto-playing video ads. Such ads are designed to be disruptive and stands in the way of people using browser for their intended purpose.

Google will not weed out all ads from Chrome but will block all ads that repeatedly violate standards set forth by Coalition of Better Ads - a group of online media and publishing industries including Google, Microsoft, Facebook, Unilever, etc. So the "Better quality ads" that pass Adsense quality checks will still continue to exist.

Reliance Jio launches websites for JioCinema and JioTV

Reliance Jio has created a digital revolution in India after the launch of a free unlimited 4G network. This attracted users to surf videos from their mobile on-the-go.

Mobile internet users increased ten folds in just a few months along with the sharp rise in sales of 4G mobile handsets.

Reliance Jio provided a bunch of useful apps within the MyJio bundle. JioTV and JioCinema are the two most popular video streaming apps. As these apps are mobile-centric, and so users were restricted to mobile and couldn't access them on bigger screens. The only alternative to this was to emulate the mobile device on the computer, but it is too technical oriented and not easy for non-technical users. Bingo to Jio users to know that the web version of these apps is now available !!!

Reliance Jio made these web versions available silently without much marketing and so users are still not aware of this provision.
