Yes, the cost of not investing is something huge to consider.
Yup, first heard of Bitcoin in March of 2013. Invested 10K in hardware, 3K for 129 GIG/h of BFL stuff which we have yet to see and the other 7K i custom built 4 rigs with 8 7970 cards, so far those 4 rigs have mined about $4800 CDN worth of BTC as of Apr-23 plus various ALT coins so we're doing okay but have a ways yet to break even on hardware. The Wife is into it now and she scarfed one of my rigs to mine PPC
