A couple of questions for those familiar with Bitcoin. Ease of use? 1a) How easy is it to transact Bitcoins between people/businesses? Is it as easy as PayPal? 1b) How easy is Mt.Gox to use for daily transactions? 1c) Is it easy to sell Bitcoins? E.g. $10.74USD weighted average. Does that mean I should be able to sell 3 Bitcoins within a few hours at that price? Mining? 2a) How much would a low-cost FPGA mining rig cost? 2b) Any standard mining rigs available for purchase? 2c) At the present mining difficulty, how much energy (Kw) would be required to mine 1Bitcoin from that FPGA mining rig? 2d) Is the mining software easy to configure and start running? 2e) Which mining pools are recommended for newbies? 2f) Will I need to hire a software-engineer/mathematician to maximize my mining rigs potential? Bitcoin 3a) How many Bitcoins have been mined so far? How many are left? Security 4a) Any one had the experience of having their Bitcoins stolen? Many thanks.
