Hi, It' is possible. We need to modify the source code of a current bitcoin client and to have our own bitcoin server to distribute loads for bitcoin mining. We will need to synchronize our server with the universe of bitcoin servers to have updated the BITCOIN BLOCK CHAIN which is over 6GB of size and growing exponentially. Now this app is not enough, you will need a website to offer users join in your bitcoin network mining pool. I offer you to develop a fully functional bitcoin exchange based on BUTTERCOIN. If we used buttercoin as base for your bitcoin exchange we will saved days for using in other issues related to developing. I really love bitcoin, it is the future. With your budget you can't buy a BUTTERFLY BITCOIN MINING CARD. They are so expensive. But we can join together and make a mining pool. The BLOCK CHAIN is over 6GB and is growing exponentially so I am sure this is the right moment to invest in a bitcoin of any kind. So, I can do the following activities: install Bitcoin daemon on any flavor of Linux OS. Secure bitcoin wallets by verifying computer operating system is not compromised. Usu Front-end APIs for bitcoin daemon which are hosted on GITHUB not just written in Ruby but in many others scripting languages like python, php, perl. Use any library or API based on JSON with support for RPC and binding with bitcoin daemon. I had used bitcoin in Amazon EC2 with two modalities: bitcoin solo mining and pool mining. I can start working immediatly.
