It is too expensive. I do not know where the guys met Baikal for 720 dollars, as I saw the offer for 1200 USD and more. Probably, these were used miners. However, they say, you can get +20 USD profits with it monthly.
I'm not sure that now it makes sense to buy this equipment now. Profitability is extremely low. If the market recovers, it will make sense, but for now there is definitely no.
