1 - It is strange that all our accounts wiped out , but the signal provider's account still alive, but it was about to explode too, but I think he has added money to his account in the last moment to keep it alive.
2 - About this EA you talk about, as you said on DEMO , is very nice on Demo accounts only, like all EAs, but in real live accounts is totally different, we tried this EA since was launched , that was abut 2 or 3 years ago, its price is high , and performance is very low , it is dangerous, just be carful with real money if you will buy it.
3 - Just to see how do they deceive people, on their site, you find the word ( Live results ) in blue cololr, just click on it, you will find only demo accounts , and back tests, all this is useless with real trading of course.
4 - The live account they put on their site, is stopped in the year 2013
so, in light of this , what can you expect from those people , you can judge .
I lost a lot of money too , more than you, with (Queens money collector ) , also , lost a lot of money with other scammers.
That is why I do my best fighting scammers, and not to let anyone else become a victim .
Wish you good luck
