In my earlier post, "Bentalefin.com - Scam or a changing business model?" I came to the conclusion that,
Bentalefin.com is, unfortunately, no longer a site to recommend that people experiment with.
It is also now certainly not a site i'd risk $500 USD on to find out if i can withdraw earnings. So unless you want to send over the $500 for hash power, the jury will have to remain out on whether this is now a scam.
It seems the verdict is now out, #SCAM. For the last week all you see from Bentalefin.com is:
502 Bad Gateway
nginx/1.12.2
No communication with customers.
The site is gone, and it would seem the money of its mining investors.
