Re: What dramatically changes the profit-mining ratio??

I look at https://www.whattomine.com every week or so to see what to point to for (ASIC, GPU).

One week, much is (very slightly) profitable.
Another, like now, everything is not profitable at all.

Sure, BTC was $290 now $279 - but that's not enough to make the difference.

How do all the margins move so dramatically - but together? What am I missing?

Thanks!

New miners (GPU and ASIC) also change it.

sure!!!
new scrypt and sha-256 asic miner, double hashrate, with the same power consumption, so, GPU mining is kikked off...
for example...
take a look to this
:
http://zoomhash.com/collections/asics/products/110mhs-scrypt-asic-plug-and-play-1000w-a2mega-door-to-door-within-3-5-business-days

110MHash scrypt, for just 1000w...
until some monts ago... unthinkable!!!!

but, that's $7/day at best... for $1,350 - that's 192 days at current rate to BREAK EVEN.

I have yet to find a miner one has to purchase that projects profit. Am I wrong?
