Jewelfxtrade already got their domain suspended, which is a good thing. All the others still remain up and running, though. I'm not familiar with the process, but you are able to report these domains on whois, right?
The sheer amount of sites that contain the exact same layout and content is worrisome, given the fact that it suggests it is extremely profitable for the admin to continue to host these sites, and the amounts scammed are probably significant (and majority of times go unreported, it seems).
Though, in regards to Crypto Green FX, you really don't need to look any further than their FAQ
The amount of return after making the investment if quite high. You can expect a lot of profit. On an average if you calculate you will be able to get the return to almost 70 percent. No other option other than CryptoGreenfx can help you make such profits. The more you will invest the more will be your return.
Kudos to them for making me laugh, I guess.
