Hello Linux Geeksters. As you may know, Bitcoin is a descentralized digital currency developed in 2008. First you choose a wallet application and share your bitcoin address, to be easy to find. Via Bitcoin, you can buy games or pay for hosting, and, unlike paypal, there aren’t many comissions. For more information on how to earn bitcoins, see the official site.
Bitcoin-qt represents the bitcoin wallet, and bitcoind is the bitcoin daemon.
The latest version of the client available is Bitcoin Core Wallet 0.9.2.1, which has been recently released, coming with improvements for Ubuntu 14.04.
In this article I will show you how to install the Bitcoin Core Wallet 0.9.211 client on Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Pinguy OS 12.04, Elementary OS 0.3 Freya, Elementary OS 0.2 Luna, Peppermint Five Deepin 2014, LXLE 14.04, Linux Lite 2.0 and other Ubuntu derivative systems.
Because it is available via PPA, installing Bitcoin Core Wallet 0.9.2.1 on the listed Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE and Linux Lite systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the bitcoin package. Like this:
