October 2017 is when I first heard about the term "Blockchain", I was in Dubai attending GITEX Technology week exhibition, I remember that I've heard a lot more than 10 times a day. At that time I didn't know exactly what it was about, so I started wondering if it is:

- A process?
- A new digital technology that has to do with financial issues?
- A program that will facilitate our daily financial chaos.
- A block of chain…. but to do deal with what? Which field or scope of work, really didn't know.

Trying to understand and coming from very little background on trading online, I did what most of us would have done : GOOGLE it !!

Wikipedia didn't make it any easy although it defined it as:

A blockchain – originally block chain – is a continuously growing list of records, called blocks, which are linked and secured using cryptography Each block typically contains a hash pointer as a link to a previous block a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data.

For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.

With a little more search I found that there are hundreds of websites and articles addressing the blockchain/cryptocurrecy new era world, when trying to find out how many digital currency there are I came across the website CoinMarketCap that lists no less than 1,037 different types of cryptocurrencies (that was on the 8th August 2017, on 6th December 2017 they are 1326), 626 of which have listed market caps of at least $100,000

At the top of the list, of course, is bitcoin, with a market cap of $55 billion (today 6th Dec 2017 it is 220 $billion). Ethereum is a distant second with a market cap of $25 billion (now it is $43 billion), but there are seven other cryptocurrencies with market caps over a billion. The currencies include Ripple $6.8 billion (now it is $9 billion), Bitcoin Cash $5.1 billion (now $25 billion), Litecoin $2.3 billion (now $25 billion), NEM $2.3 billion (now $2.5 billion), Dash $1.4 billion (now $8 billion)), Ethereum Classic $1.4 billion (now $2.8 billion) and IOTA $1.3 billion ( now $13.1 billion).

My google search didn't answer the majority of my questions, therefore I decided to take an online course on Udemy to which I got addicted lately assuming that it will give me more reliable fruitful information that may feed my hunger and curiosity for the booming topic.

Crazy: I would say tooooo crazy Scary: I would say risky at this stage Bubble: no one can be sure if it's a bubble until it bursts Profitable: very profitable at this stage Herd behavior....very clear and it will escalate from now on

Invest in: would I personally invest in: I need couple more days to digest and understand the game more but I created the account and already have a wallet. If I am planning to invest, it would be a small amount that I am ready to part with should the bubble bursts.

Replace cash/plastic cards (debit & credit), any other current payment methods: to simplify this point I would ask: would my kids ask for bitcoins in the near future to buy stuff, definitely yes and it's a matter of time to have the digital currency revolution.

What scares most: that no one knows Mr. Satoshi Nakatomo - the Japanese gentleman who created all this mess, and miners job is not clear enough for nonblockchainers.
