Just doing a little more recon on bitfury.shop.

1.  It's behind CloudFlare
2.  Bitfury.com is not behind CloudFlare
3.  http://www.crimeflare.info/cfs.html - reveals an IP address possibly associated with this cloudflare account.

Some CloudFlare-user domains with a direct-connect IP address of  185.145.131.236

Hmm..

Then using the leet hacking tool of Google - dolbonavt@gmail.com  email address comes up with some not-so-nice results.

Run, don't walk away from this deal.
