Like any investment you need to weigh your risks rewards. What I am doing is purchasing as they continue to fall... however I am also investing heavily in rigs. Either build your own or search here on the forum to read reviews on companies that are building/selling them.

Best for luck... it is still extremely new and a needed source outside of the over regulated financial industry!

I to am pretty excited about the opportunity to mine for Bitcoin's, and from what I can tell you can have a decent ROI if you are patient. I also placed an order from BFL, and even though they are back ordered, I really haven't seen anyone else stand out as a leader in rigs. I did see KNC and then yesterday I noticed on CoinDesk a new company called Krater opened...

Any who... would be fun to build one myself as well

Get em locally... I personally don't understand why it matters if they are anonymous or not... try localbitcoins.com... where are you located?

this should help you https://www.kncminer.com/pages/tandc

I would rather buy then build to be honest... what is anyones experience/reviews on either going with KnC or ButterFly?
