I had interaction with this company. Sent them money via wire and they claim they never received the money. I started investigating. Do a Whois lookup on their domain name... it is registered in Panama with hidden credentials? Their business was recently registered in the UK in Nov 2020? Creditably report on their domain came back as 2% creditable... 98% likely fraudulent? They are "selling" new miners $1000 less than what the manufacturer is selling the same item (this is too good to be true)? Address on web site is a street name, not a specific address? Communication is lacking and not specific when pointed questions are asked? My bank in Canada & the bank in the UK worked together in agreement that this "business" is likely fraudulent and they were able to recover the funds that were wired to BitmainExpress. I am in the process of reporting this to the Cdn government fraud reporting service as well as the same in the UK. My advice... "Do Not Deal With This Company!" If you have experienced the same I encourage you to report your experience to your government agency that deals with fraud.
