Firstly here is some in-depth info on it: https://en.wikipedia.org/wiki/Cryptocurrency
To simplify cryptocurrency I will work with bitcoin as this is the gold standard and the original cryptocurrency. Bitcoin as the rest are recognised actual currencies but they are purely digital, you can buy, trade and sell them just like any currency. Now in order to keep Bitcoin you will first need a “wallet” and this is essentially an account where you keep you Bitcoins.
I would highly recommend using localbitcoins.com, here is a link to their site: https://localbitcoins.com
Now firstly you will need to register an account, this will then mean you have your wallet ready. secondly you can view people in your area selling Bitcoins, all you need to do is choose the person who offer the best rate, best feedback and most suitable payment method for you. Ideally bank transfer. All you need to do is choose how much you wish to buy and click buy, the seller will get in touch with their bank details and you can transfer payment to them. You don’t need to worry either as once you have transferred payment the Bitcoins are booked with the seller and held in escrow until you confirm you have received them.

Right now that you have a Bitcoin wallet and Bitcoin you will be able to deposit into quartercore.co. Firstly you need to register and account, once this is done you receive an email, within this email is a link which you will use you confirm the and activate the account. Now that you have an active account you can move to deposits. Now here is the information on how to deposit, (https://www.quartercore.co) please note we used a “Blockchain wallet” instead of “localbitcoins” but dont worry as they both operate in the same manner. Stick with Localbitcoins for ease of use.
