i bought my first batch the Saturday of Easter weekend last year @ $1.60. wasted about 2mo prior dicking around on OTC trying to buy but not knowing what i was doing with that. i then started selling silver in May which silverbox can't ever seem to get straight.
I got interested sometime at the end of 2010 or begining of 2011. Even downloaded the source code (which is a prerequisite for most any software I'm interested in and think I may need to trust.) The driving force was a desire to help fund something I thought was worthwhile. Maybe wikileaks, but I don't fully remember.
Alas, my attention shifted to finding and buying some property which finished up in like June 2011, then I got re-interested Bitcoin. By the time if figured out the ins and outs of obtaining Bitcoin it was down to around $16 from it's $32 highs.
Thankfully we all got another chance to get our foots in the door on the way down to $2, and I inserted my foot and a portion of my lower leg. More than I anticipated.
Not sure what a 'DCA' is and am to lazy to look, but I suspect from the context it is the break even point. For me it's around $6/BTC. Looking forward to hearing from my dear friend cypherdoc on this (but would fully understand his or anyone else's reluctance to share such details as it is not a good idea to do so for any number of reasons.)
