Even you probably know, mining Bitcoin from home is literally impossible, but there are some altcoins beside bitcoin that can be mined through traditional way of mining, with your own GPU or CPU.
Bitcoin is the first successful cryptocurrency ever, so it is pretty logically that it is most popular, but many others cryptocurrencies are developed as a result of Bitcoin\'s issues, these cryptocurrencies are called altcoins and there are many of them. They are arriving the market through new funding mechanism called initial coin offerings (ICOs).
The most popular cryptocurrency beside bitcoin is Ethereum, which is decentralized platform based on smart contracts where people can negotiate with the contracts without third party and get funded for their idea, projects and applications through ether, official currency of Ethereum. Ethereum is the second large cryptocurrency due to market capitalisation which is around $41 billion.
Another good cryptocurrency is Litecoin. Many people compare Bitcoin to gold, so if Bitcoin is gold, Litecoin is silver. It has market capitalisation around $17 billion, which means that it is smaller than Bitcoin and Ethereum but it has one good characteristic, the speed of transaction process.
All the cryptocurrencies mentioned above are based on blockchain technology. IOTa is new cryptocurrency based on directed acyclic graph (DAG) technology. This system enables free transaction.
Monero (XMR) has one characteristic that differ from other cryptocurrencies. It is privacy, where transaction is completely private and untraceable, so no one can link some transaction to a particular user.
Ripple (XRP) is also popular cryptocurrency and it differs from other cryptocurrencies with the fact that it doesn\'t require mining. Released in 2012, with the main idea to make international payments low cost and easier.
