Cryptocurrency
Cryptocurrency is decentralized digital money designed to be used over the internet. Bitcoin, which launched in 2008, was the first cryptocurrency, and it remains by far the biggest, most influential, and best-known. In the years since, Bitcoin and other cryptocurrencies like Ethereum have grown as digital alternatives to money issued by governments. There are now over 20,000 different cryptocurrencies in circulation.
Buying
The easiest way to acquire cryptocurrency is to purchase on an online exchange like Coinbase, which is the world's most trusted and most secure platform to buy, sell and manage crypto.

Hiveon
Hiveon is the ultimate mining platform which allows users to setup, mine and control processes more effectively and hassle-free across thousands of rigs all from a single place. Everything you and your team need to keep your farm at peak efficiency.
- Farm = a group of rigs which mine.
- Rig = a mining device equipped with a motherboard, CPU, RAM, SSD/HDD, and GPU.
- Worker = a piece of hardware which will mine.
Setup
I really needed these simple, step by step instructions because it is not clear and some of the links are dead (sigh).
STAGE 1
- create an account at Hiveon
- confirm the link in the email
- log in
- your first farm will be automatically created
- click add rig
- follow the wizard to download the Hiveon OS and burn it to your USB drive
- in the wizard, download the rig.conf file
- when the USB drive has finished being created, take it out, then back in and mount HIVE partition
- copy that rig.conf file to the HIVE partition and then unmount the drive partition
- pull out the drive and put it in your mining rig computer
- start the computer and watch your Hiveon Dashboard for the rig to appear in your farm
