If we consider the cost of electricity in many countries, it is best now not make new rigs. But in some countries, there are low-cost electricity. If you have free electricity, it changes everything.
I'd say anything below 0,10$/kW is still worth it.
You can always build 4-5 GPU rigs with cheaper PSU's and eventualy mine monero for low power usage.
Anyway, i'm still buying GPU's, i think there will always be something to mine, even in a few months when ETH ends and ZEC dissapears into oblivion

There will always be something to mine.
Besides my RX series, I'm still runing R9's and 79x0 series on ZEC, they don't bring much profit, but still are far from over.
The difficulty that would drop onto everything else after ETH turns PoS and ZEC gets flushed would do more than double the hash rate for everything else. You can't look at the current profitability of XMR or any coin.
If your R9 and 79x0 cards are little profit now, they likely wont be profitable to run soon.
not true, i think there would be a massive sell off of many mining rig, if the diff triple on everything there will be no more profit for everyone, only peanuts for those that have lower than 5 cent electricity
If the ETH goes to PoS, then the difficulty for other coins will rise. That is the reason I am not expanding.
ETH is planned to go PoS
ZEC is just a glorified pump and dump coin. The hike back in value is a blessing for me to get more earnings prior to the BTC ETF but besides that it is a coin waiting to die
It will be grim in due time if 2 of the 3 biggest mining coins go down
I completely disagree with this.
ZEC is a rebate/commercial supported by
INTEL
AMD
NVIDIA
ASUS
ASROCK
BIOSTAR
EVGA
GIGABYTE
MSI
SAPPHIRE
POWERCOLOR
CORSAIR
SEASONIC
ANTEC
GEIL
MUSHKIN
AND MANY OTHER COMPANIES
simple economics any of the companies above simply buy some coin to prop up its price.
this encourages miners to buy gear.
why is ZEC the best coin for this at the moment?
market cap is small so it is easy to support the price.
