The current situation i'm not sure about, but to my knowledge XM had licenses from not just Belize, but Australia, Cyprus and UAE. Also compliant with MiFID directives. Finding info about all that was what first brought me to this broker. Right now, I think there's less regulations, but I'm already here, and already got my payout like 10 times, so leaving or getting worried right now would be pointless.
So far, my trading here was fine. Lots of assets, the platform works alright. Most importantly, the broker does not interfere with my trading. Everything else, I can handle.
