In the not too distant future, you are likely to live in a world underpinned by blockchain—the technology behind the cryptocurrency, Bitcoin. The technology has instigated a new generation of young companies looking to invent applications, and we are already beginning to see the results. Imagine being able to vote in the upcoming Brexit referendum on your phone, or make an offer, complete an exchange on a new flat in an afternoon? As unpractical as this sounds, it is where we are headed.

Do you find it easier to learn new things by watching? Then you may want to watch this - if you have an iPhone that is. This video by Tech Insider shows you 5 hidden iPhone features that only power users know about. From head movement screen control to LED flashing notifications, they are all cool, even if a bit geeky.

Like you, we have been frustrated with telecoms providers before. Whether it is a mobile phone provider that bounces you from one call centre rep to another, a business phone company that sends a proposal with 20+ spelling mistakes, or a high speed broadband supplier who is anything but high-speed, chances are you have had an appalling experience somewhere down the line. BT and Vodafone, despite their claims and excellent advertising, would appear to be two of the worst. In fact, a Vodafone customer recently had such a horrific experience that she wrote a play about it! Read the play here. The irony is, they are two go-to brands for most people looking for a mobile or business phone system.

It is every company’s worst nightmare: unhappy customers who tell everyone how poor their experience with you was. Not only do you lose their business, but you lose the potential business of the people they have spoken to. It is the butterfly effect in the worst possible way.
