    Bitcoin a hope for youth!!!   Inception and Early Days: - Bitcoin was created by an unknown person or group of people using the name Satoshi Nakamoto. The domain name bitcoin.org was registered on August 18, 2008, and later that year, on October 31, a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” was published, detailing the methods of using a peer-to-peer network to generate what was described as “a system for electronic transactions without relying on trust” 1 .   The Genesis Block:- On January 3, 2009, the Bitcoin network came into existence with Satoshi Nakamoto mining the first block of Bitcoin, known as the genesis block, which had a reward of 50 bitcoins. Embedded in the genesis block was a text referring to a headline in The Times about the instability caused by fractional-reserve banking 1 .   Early Growth and Development:- Bitcoin saw its first commercial transaction when programmer Laszlo Hanyecz bought two pizzas for 10,00...

What Happens When You Delete Your Instagram Account?

Image
  As Social Media platforms like Instagram gained tremendous precedence over the last decade, our lives also began to get tangled deeper with the virtual. While many GenXers and older GenYers began focusing on creating and maintaining an online presence, seeing both professional and personal value in this activity, our children and young Gen Xers don’t even require any kind of intent. This is the norm for them now. The point is that the line between real and virtual has been steadily disappearing over the past decade. While there are those who have not just accepted but are also thriving in this new world, there are those of us who are simply not cut out for this. Because for all the good that it’s doing, Social Media is also extremely addictive and not everyone is cut out for it. With users looking for an out by deleting their accounts and thus living an Instagram free life, we would like to make this transition to a social media-free life easier. So now that you’ve left Instagram...
