XM (formerly XEMarkets) is a Cyprus-based forex and CFD broker founded in 2009 and regulated by the Cypriot financial supervisory authority CySEC. XM is also regulated by the British Financial Conduct Authority (FCA) and is registered there as a financial services provider. eToro is one of today's best-known forex brokers, which certainly has to do with the broker's aggressive marketing, but the fact that the trading platform is available in over 20 languages should also contribute to the broker's seriousness. eToro claims that it has more than two million customers from all over the world.
