Thank you for reading, I am Dukefish, an EOS advocate and this is a standalone article intended for my real life friends who have no idea what I have been talking about since posting here on Trybe and spamming them on social media. I hope it serves well as providing education and reference for those of us already in the crypto world.  There is an amazing set of videos by TrybeTV to help educate those in more detail here.

So What is a “Cryptocurrency”?

A cryptocurrency is a financial system that exists without banks or an intermediary authority, built on a emerging new technology called blockchain. It is creating a new way for people to send a new type of money to one another. The digital money became known as cryptocurrency, taking the stem from the  cryptographic process of math that underpins how it works.

And what the hell is “Blockchain”?

Just like traditional banking and database systems there has to be a ledger. A record of transactions and exchanges between accounts. Blockchain is a new type of distributed ledger, where it is stored across hundreds/thousands of computers and not just in one the hands of one big central entity. In the same was traditional ledgers work , blockchain creates a growing list, (or chain), of time-stamped transactions. But the advantage of this new medium is that due to the decentralized nature this ledger cannot be altered or tampered with in anyone. Each new transaction is added as a “block” to the chain. Blockchain has advantages to traditional methods due to it offering a verifiable, immutable and public records.

Okay, well I have heard of Bitcoin in the news before, what is it?

Bitcoin (BTC) was the first cryptocurrency brought into existence in 2009 by anonymous founder Satoshi Nakamoto. The vision was to create a “peer-to-peer electronic cash system”. Although bitcoin is the best known digital coin and has the largest dominance of all the other cryptocurrencies in the marketplace many other cryptocurrencies have been born since its initiation all those years ago. In January 2018  BTC  made headlines as one bitcoin was worth in excess of twenty thousand US dollars!

So what now? 

As with any new technology space it is important to learn and to discover this space for yourself. Yes it is a market where money can be invested and profits can be made, but it can also be a huge risk and you could lose it all. If you are looking to move into this world, proceed with caution and be prepared to risk only which that you can afford to lose.

Again TrybeTV offer an amazing introduction video series to help you understand what the hell is going on here!

  • Exchange – A platform for users to trade and exchange tokens.
  • Fiat –  Traditional monetary systems, example USD, Yen, Euro, Gbp etc.
  • Fork – A fork  is where technical difference/update or ethic divergence creates alternate versions of a blockchain. Thus splitting the blockchain into new ones and/or running simultaneously on different parts of the network.
  • Forging – Verifying transactions without a block reward, instead relying on transaction fees as the sole incentive. Common in proof of stake blockchains.
  • FOMO – The Fear Of Missing Out. The emotional response that makes people impulse buy tokens at their all-time high. 
  • FUD – An acronym for “fear, uncertainty and doubt”, used in online forums when discuss negative news/media attention/commentators etc
