if there is nothing that I can do, then it is obvious that using cryptos is a scammers paradise because there is no protection to buyer (that I know),
well the buyers can simply do a quick google search and find reviews of the merchants that they are trying to use. specially when it is a website that is selling mining hardware! when you find negative reviews or in this case nothing at all (since it is apparently brand new) that should raise some red flags for you to not use them.
since this website has the word "antminer" in it, you can contact the real company's website (
https://www.bitmain.com/) and ask whether they have any kind of affiliation with antminerusa.com, this site may simply be abusing their brand name to scam people.
the protection that you as a buyer could use is an escrow which at its simplest way can be a 2 of 2 multi signature address between you and the merchant but the best way is to use a third party who has no stakes with either side and do a 2 of 3 multi sig.
unless there is a way to introduce the complain in the chain in order to reverse payment.
sorry, bitcoin transactions are not reversible.
Buyer is not looking for first on google about the website before sending his bitcoin, we have asking at the group about information website trusting, any one have make payment at this website or not, we are looking at payment method only use bitcoin or not, but if trusted website always have many kind of payment e currency not only bitcoin.
