The advantages of cryptocurrencies over fait currencies or paper money/cash

Helloo everyone, am here today to talk about the similarities and the difference between the fiat currency of a given country and the cryptocurrency . This was one of the problems I encountered while trying to introduce a couple if friend to steemit and crypt I currencies or Blockchain in general . In the view of this I decided to make a little post at the best of my Knowledge and will still tag some steemians that are now lords in the system to throw more light in this issue. I also invited them to my blog so am very sure they will see it. This is not just for these set of people am introducing it will also be very useful for newbies that are in the system but don't have the full knowledge of it yet .
[I will be using their questions as subtopics]
Now let's go,these are some of their questions.
WHAT IS CRYPTOCURRENCY?
(In a lay man's language so they could understand) Cryptocurrency is just like the normal currencies we spend on goods and services we enjoy . But they are decentralized and are valuable in every country you found your self . These monies are used by blockchain ...like steemit e.t.c
CAN THIS CURRENCY BE INVESTED?
(With a smile)... Yes of course , cryptocurrency can be invested and more will be earned through the investment. You can either buy or sell ,or spend it on a commodity or for a service enjoyed .
HOW DO I FIND CAPITAL TO INVEST OR EARN?
Now that is the reason why I want to join the steemit community ... Unlike other Blockchains steemit pay you for being creative ... And what it means is that as a newbie you can start up with no capital ... All you need to do, is to do the same thing you do in the social networks like pictures ,video, write-ups ,sounds e.t.c. more over in steemit you can also earn through making a good comment on another persons post.. Every valuable post has a place in steemit... Just add value to life and get paid for it.

DO I NEED NEED REFERRAL OR WEB OF PERSONS UNDER ME BEFORE I EARN?
... No you don't all you need is to follow person to see their post while others follow you. You visit other people's blog for their posts while your blog will be visited .
IS THIS CURRENCY STABLE WITH IT VALUE IN THE MARKET OR CHANGES?
..... No it is not , just like the US dollars ,the Euros, Nairas e.t.c it get high at a point in time and gets down in another. But with the constant use of steem and introduction new members into the steemit it gets higher .
HOW DO I GET STARTED?
(Smiles) You get registered and when you conclude you registration process you make your introductory post ,follow some bloggers, while other bloggers will follow you ...make your posts with tags according to the post, that is the topic and the content of your writeup .
WHAT IS A TAG?
In steemit , tags can either be a direct access to a community blog in the system. For instance , if you write more of love contents or about poetry, e.t.c ....you use this tags ..."love,poetry,writing, life e.t.c" there are many tags and they all represents a given community . we have some like steemjet..... Which promotes creativity and promoting steemit globally, wafrica,Starch,cryptocurrency,steemit,steem e.t.c
In steemit these tells the content of your post and when you use some of these tags, the community can upvote your post if your post is consider valuable.
....... WILL BE STOPPING HERE AND WILL STILL UPDATE YOU ALL OF THEIR REPLY AND WHAT THEY BELIEVED ABOUT STEEMIT AND BLOCKCHAIN IN GENERAL .
I will be calling some of my chairmen, @yungchief , @jacobite ,the boss Steen jet community Nigeria @uchenna. To throw more light on this topic in general ...and other things one should know about steemit and cryptocurrency in general. Thanks in anticipation
