They're selling at $4600 for two units, so $2300 a pop. Earning is around $24 a day, so break even in a couple of months. Why is everyone saying they won't make their money back?
You won't. Making X amount a day to break even in a couple of months isn't an accurate measure to recoup your investment. If you're looking at whattomine or whatever, what you are seeing is a snapshot of rewards at the current point in time. *Assuming no other miners come online and the difficulty stays the same - that's not gonna happen so if that's what anyone is assuming, they'll be sadly mistaken.
When manufactures flood the market such as Inno and continue to sell an infinite supply ASICS, the hashrate goes way up and rewards diminish rather quickly. When profits diminish, they adjust the price of the ASICs so people think they're getting a good deal with a discounted price. But guess what happens when all those "discounted" ASICs come online, that $24 a day will quickly be reduced to $15, $10, $5, $2.
It's all a cat/mouse game and you're the measly mouse they're the Lion. They don't give a fuck about customers making their money back, evident with how quickly new batches are made available for purchase. Read the thread from the beginning when people where happy and jolly to now EVERYONE is pissed. There's a reason why Inno no longer responds or contributes to this thread. They fucked us and they know it.
You're better off buying actual coins than mining.
