I've been working with them almost since the platform appeared on the market, even before the launch of the official affiliate panel, and I can say with confidence - the terms of cooperation are getting worse and worse. The changes in affiliate fees are not for the better, and the rules of participation have become much worse. Therefore, from my experience I can say for sure - the market leader is clearly not Olimptrade. I have stopped sending traffic there because there are affiliate programs which pay much better and over the whole "life" of a referral rather than a couple of months as in KingfinTrade. That's why I now send my traffic there.
