I'm not going to buy any of these machines- numbers aren't that impressive, and profitability at this moment isn't exactly conducive for this thing to break even, much less make you profit within a year. As others have said, the profitability at this point in time seems pretty high, but difficulty corrections once everyone gets their hands on these miners will drop profitability down quite a bit.
Everyone's going to get the miner at the same time, including retailers, and it just doesn't add up that this new miner selling site happens to have these units in stock. Additionally, they only accept non-reversible payment methods (bank transfer or crypto), so you have no chance of getting your money back if this site just takes your money, and there's already a thread against the site
here. The account that made this post is also brand-new, so there's a high chance that this account was made for the sole purpose of promoting this most likely scam site.
