everything on their mining page is a red flag after red flag.

if they actually had the hardware, giving every new user 30 days free mining on an Antminer S21 XP, would be like flushing money down the toilet for them.
not to mention the bonus hashrate you get the longer the "contract" you buy

also, they are selling mining hardware for way below market price:

i'm sorry, but i don't think you are going to get your money.
On the same day, they sent an email requesting confirmation of my phone number and email address, a selfie holding my ID, proof of the most recent fund transfer to ecos.am (such as a screenshot from the banking app, a transaction link, or an email confirmation), and the wallet address to which the withdrawal request was made.
did you send them that info in an email reply? if i were you, i would be worried about identity theft.
