If you have always been interested in trading NSE shares, the best way to learn is by doing. However, you might not have the cash to undertake the actual trading. It is also not wise to start the journey of trading with real cash due to the risks involved.

This is where the concept of Fantasy or Virtual Trading comes in. This is where you trade in stocks without investing actual money.

In a simple and costless approach, you could just use a spreadsheet. You decide an amount and buy shares based on the price at a given day. Days later you feed in the current price and see if you would have made a profit or loss. You then learn from what you did right or wrong.

You can also use the NSE virtual trading App or website. Here you will pay. For every KShs 100 paid you get KShs 10,000 to trade with. Just for emphasis the KShs 10,000 is not real money. It is just a virtual float which allows you to buy shares.

The good thing with the NSE platform is that you don’t need to do any calculations as you would on a spreadsheet. You also wouldn’t need to input any prices since the platform gives you the live prices from the NSE.

The virtual trading platform is however not an exact replica of the real thing. But it can be a good place to start. NSE needs to do a lot of work to make the simulator be as close to the real thing as possible.

It is rather strange that NSE does little to sell this product. It also doesn’t invest in keeping it updated. This if well harnessed can become one of the best cash earners for the Exchange. Alternatively they can concentrate on selling data and allow other developers to produce more advanced simulators.


Eight Inconvenient TRUTHS About BITCOIN and Other CRYPTOCURRENCIES

The problem with most cryptocurrency investors is that they treat the cryptocurrency craze like religion. They never listen to the inconvenient truth. Below are some realities of cryptocurrencies which the enthusiasts find hard to swallow;

Cryptocurrency is backed by nothing and its price can be anything between zero and infinity. This results in extreme price volatility. You need nerves of steel to trade in something like that.

Cryptocurrency is not regulated by anyone and in case of loss there is no recourse in law or anywhere else. There is no one in charge. Nobody can manage the chaos in that space. It is a technical madhouse in which order cannot be enforced.

Cryptocurrency investment and trading carries such high risks that it cannot be differentiated from gambling. Such trading is highly speculative and carries massive risks because there are no circuit breaking mechanisms during times of high volatility.

Cryptocurrency trading uses computers and exposes the traders to risks of hacking. Your entire holding can disappear in a flash.

There is a lot which is unknown about cryptocurrencies. As such, a lot of scammers have built their business around these virtual currencies. It is hard to tell what is fake and what is real. It is impossible to tell what will last and what will fade away soon.

Investing in cryptocurrencies is an investment in hope. The future of cryptocurrencies remains shaky. The jury is still out there as to whether this is the greatest financial scam in history or whether it is the ultimate investment miracle.

The idea that a person can create money using a computer sounds too good to be true. If something is too good to be true it probably isn’t true. The cryptocurrency fantasy is impressive but not convincing.

The anonymity of cryptocurrency trading makes it susceptible to criminal activities. As such, risks of regulatory crackdowns will always be there. Such a crackdown can easily render your investment useless as cashing out could be outlawed.

Always bear these things in mind before taking a plunge. Also remember the risks of gambling such as addiction and emotional intoxication. Something this speculative can be addictive and enslaving.

Before trading in cryptocurrencies, it is better to trade is in less risky assets in order to appreciate how such trading works especially with respect to the cyclical nature of markets.

How a Cell Phone User Can be Secretly Tracked Across the Globe

How a Cell Phone User Can be Secretly Tracked Across the Globe


Since we are living in an era of Mass surveillance conducted by Government as well as private sector industries, and with the boom in surveillance technology, we should be much worried about our privacy.

According to the companies that create surveillance solutions for law enforcement and intelligence agencies, the surveillance tools are only for governments. But, reality is much more disappointing. These surveillance industries are so poorly regulated and exceedingly secretive that their tools can easily make their way into the hands of repressive organizations.

Private surveillance vendors sell surveillance tools to governments around the world, that allows cellular networks to collect records about users in an effort to offer substantial cellular service to the agencies. Wherever the user is, it pinpoint the target’s location to keep every track of users who own a cellphone — here or abroad.

We ourselves give them an open invitation as we all have sensors in our pockets that track our every move wherever we go.



The tracking technology takes advantage of the SS7, a global network, which is unfortunately vulnerable.

SS7 or Signaling System Number 7 is a protocol suite used by most telecommunications operators throughout the world to communicate with one another when directing calls, texts and Internet data. It allows cell phone carriers to collect location information from cell phone towers and share it with each other. A United States carrier will find its customer, no matter if he or she travels to any other country.

The Washington Post published an awesome article on surveillance technology that can track cell phone users anywhere in the world. Surveillance vendors also now have access to SS7, so that their customers can home in on somebody’ locations as precisely as within a couple of city blocks (or in rural areas, a couple of miles).

These systems are so effective that it can even detect how fast a person on a city street is walking, or the speed a person’s car is traveling!

The system was built decades ago, when only a few large carriers controlled the bulk of global phone traffic. Now thousands of companies use SS7 to provide services to billions of phones and other mobile devices, security experts say,” explains the post.

All of these companies have access to the network and can send queries to other companies on the SS7 system, making the entire network more vulnerable to exploitation. Any one of these companies could share its access with others, including makers of surveillance systems.


It is believe that dozens of countries have bought or leased this surveillance technology in the last few years. Having a close look at such tools, it has been discovered that some of the companies that sell SS7 tracking system are advising their customers to pair them with “IMSI catchers” or StingRays.

StingRays are common surveillance devices that allow law enforcement to mimic a cell phone tower, and track users position who connect to it, and sometimes even intercept calls and Internet traffic, send fake texts, install spyware on a phone, and determine precise locations.

What’s interesting about this story is not that the cell phone system can track your location worldwide,”said Bruce Schneier, a senior security researcher. “That makes sense; the system has to know where you are. What’s interesting about this story is that anyone can do it.”

Privacy advocates are not only worried by governments getting their hands on these systems, but also about hackers and criminal gangs using it.
