yeah antminer s9 daily profit 13$

but still around 4k$ price
Actually it's at $16+ per day and instead of dropping like a stone which your Baikal earnings are every day, it's steady.
Baikal earnings dropped from $350 per day to $60 in 2 weeks and it's not stopping. You're already stuck holding the bag.
Also I've been buying s9s from between $2100 to 3k for the past 2 weeks.
Id offer 0.3btc and hope it'd roi in a year.
