I've been driving traffic from my own site, there are no other sources and there have never been. With iq options it was more interesting, I started a year ago. At least for me. With Kingfin there is much less income, although I have less traffic as well. I have not checked the statistics, and I do not think that some of the big companies will go that low. I have not dealt with the support team, however, the positive difference from iq options is that in Kingfin they pay me instantly upon request.
