I purchased one back in May. I am waiting for my delivery patiently. It is supposed to be very reasonable when it comes to electricity.

It's definitely turning out to be a very fast race to the bottom. But here's a qualitative thing to consider, the Bitcoin mining arms race has gone through the steps of CPU->GPU->FPGA->ASIC. By analogy, it's like going from clubs to crossbows to automatic rifles to tanks. All I expect going forward is for there to be more and more tanks and better and better tanks, but not the disruption of nuclear tipped ICBMs (quantum computers?) showing up. Returning to the quantitative, one of the geeky stats on BFL for what it's worth is that the current chips are made on a 65nm process. https://products.butterflylabs.com/65nm-asic-bitcoin-mining-chip.html I'm still willing to take the effective bet here -- that buying a Butterfly Labs machine now and running it for one or two years will have a positive return (but not super great) over that period. Maybe there will even be some resell value for the device at the end of that for the sentimental/collectors value. (Tell that to the Beanie Babies! http://www.buzzfeed.com/hunterschwarz/how-much-beanie-babies-were-predicted-to-be-worth-vs-how-muc ) Given that I don't doubt the performance of my credit union, the deposit insurance system and Canada's economic fate as a whole, I'll ultimately have to compare any return after the fact against a TFSA term deposit if the profits are really tight. Jeff's right, for a higher risk, higher return, consider BTC itself. You can even lever it up 1-5x at this site if you're really bull: https://1broker.com/?c=btcusd Or, be a bear and take a short position on BTC/USD (equivalent to just holding USD if you go for 1x leverage) and earn some pretty decent interest (currently 0.14% daily!) as compensation for putting your trust in that particular market maker. (that will also go to 0 as faith in the soundness of that company as a market maker increases) Mark _______________________________________________ SkullSpace Discuss Mailing List Help: http://www.skullspace.ca/wiki/index.php/Mailing_List#Discuss Archive: https://groups.google.com/group/skullspace-discuss-archive/ _______________________________________________ SkullSpace Discuss Mailing List Help: http://www.skullspace.ca/wiki/index.php/Mailing_List#Discuss Archive: https://groups.google.com/group/skullspace-discuss-archive/
