The BTi/CoreTech CEO was formerly the CEO (and previously CTO) of SpotOption, the binary option scam run out of Ramat Gan, Israel.[1] That was a big operation. Out front were the fake "binary option brokers", in reality bucket shops, such as Banc de Binary. SpotOption provided the back-end services, while the front companies ran call centers to recruit more suckers. Some of the front companies appeared to be operated directly by SpotOption, although that was never entirely clear.
Until 2017, it was legal for Israeli companies to scam non-Israelis in this way.[2] When the binary option business was made illegal in Israel, the companies were given three months to move to another country. "Officials say that numerous Israeli-owned binary options firms have already begun moving to countries where the activity has not yet been banned." SpotOption moved to Bulgaria.
The scam goes on, under new names.[3] "Since then, some scammers have shifted to schemes involving forex trading, CFD or cryptocurrency speculation."
So that's the back story here.
