Yeah, and ROI on those algorithms will be close to infinite even for huge farms, especially when a 1080 Ti earns less than $2 a day before power.
Bether to earn $2.6 a card per day right. $0.60 increase in revenue on the same power. A 30% faster miner could be 100% more profitable if the powercost is high... Private bins is forcing the other miners over to less profitable coins.
For lyra2z you need 6-7MHASH on the 1080ti to be profitable. The dregde and the t-rex miners are much slower than this . And much slower than my mod from october 2017...
$2 a day was optimistic, right now the second best altcoin is 20% worse than ETH ($1.60 a day atm).
Even if your miner is 27.4% faster (factoring the 2% devfee out of the boost), and even if you have solved the increased stales and much lower actual hashrate than the reported - the second best non-ETH altcoin would be on par with ETH at a 50% higher power draw.
And please don't say "mine unknown shitcoins" - they all drop in value and diff shoots up within hours.
