What dramatically changes the profit-mining ratio??

[AnnaC]

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!

You are missing the crash of Sharkcoin, which was a very profitable Quark coin.
Since then, its enormous hashpower has been redirected to other coins/algo, bringing all their profitabilities down.

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

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

fake buy volume... (it isn't always the fault of the miners  )

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?

If you just point your miner at a multi-pool or just mine LTC then you won't make your money back.

But if you do your homework and mine certain coins at certain times and trade them right -- then you can do well.

no way to survive in mining without an ASIC and free electricity !
plus the certain coins & certain times does not exist anymore, cause the big guys rent freaking amounts of hash, so if you are good with TA make your money from thin air, or else buy some BTC and store them just in case!
