If you want to trade in digital currencies, you are going to need a platform on which to trade them, and an intermediary to communicate with the network. Coinbase is a global digital asset exchange company (GDAX), providing a venue to buy and sell digital currencies, as well as send information about those transactions out to the blockchain network to verify those transactions. Coinbase serves as a wallet, too, where the digital currencies can be stored. The application operates exchanges of Bitcoin, Ethereum, Bitcoin Cash, and Litecoin, as well as other digital assets with fiat currencies in 32 countries, and Bitcoin transactions in many more countries. According to its website, Coinbase has served over 10 million customers and facilitated the exchange of more than $50 billion worth of digital currency.
In the case of Bitcoin, miners run computer programs to verify the data that creates a complete transaction history of all Bitcoin. A technology known as the blockchain, which is used to create irreversible and traceable transactions, makes the process of verification possible. Once a miner has verified the data (which comes in a block, hence, blockchain), they are rewarded with some amount of digital currency, the same currency for which they were verifying the transaction history. So mining Bitcoin, for example, would earn you Bitcoin.
Ripple positions itself as a complement to, rather than a competitor with, Bitcoin - the site has a page dedicated to Ripple for bitcoiners. Ripple is a distributed network which means transactions occur immediately across the network - and as it is peer to peer - the network is resilient to systemic risk. Ripples aren't mined - unlike bitcoin and its peers - but each transaction destroys a small amount of XRP which adds a deflationary measure into the system.
