If you bought bought a Jupiter in June 2013 ($7,131.80) to date you should have made 40+ btc at roughly 510 gh/s avg. I don't know where else in non BTC land that kind of ROI exist for the average person.
Ouch! Is it really that bad? Had you simply bought BTC you'd have 70+ BTC. That's nearly a -50% ROI.
depends when you got them.. if you got them after first week of Oct you made ~55
BTC per Jupiter.. those lucky ones that got their miner a day or two at the beginning of Oct got about 7 more
BTCalso, last summer using credit cards for miners was a huge deal since you couldn't buy btc easily that way (and without crazy fees of course)
so that was a great way to leverage up on a bet on price hike for bitcoin.. right now, the price isn't worth going leveraged up even if you could use credit on miners.
but to each their own on that speculation
I agree with your sentiment and support diversifying the investment. The other benefit is supporting the network dilution, maintaining stability; there are enough opponents of bitcoin at least this line must be maintained.
