lol my A9 Zmasters were mining $50 a day when I first bought them. Now I'm lucky if I get 2 bucks a day.
$645? hehe, more like $45 per month.
That is why those asic companies earn so much money, they sell those miners making people to think they will get their roi in 3 months and in the end roi is 5 years being hopeful, realistic will never get the roi ehhe
Do not buy asics trolls!!!!
In my opinion, sellers should stop using these terms to sell their products.
It would be much more reasonable if you informed that in today's conditions and only today, it would be possible to earn that amount, but as soon as the machines were online, this profitability would not exist, since the diff will increase considerably.
That's just my opinion, with this type of advertising you could gain a lot of confidence with your buyers
