It's good to have forex trading platforms allow their subscribers opportunity of funding their accounts through cryptos. Invariably, what that means is that these platforms will also have crypto pairs they trade. It's an innovation to capture traders' interest and make trading easy too. However, one has to be careful of trading platforms one chooses because we've seen cases where rogue platforms make it impossible for traders to withdraw their profits. It's real sad that at the end of toiling one doesn't get to reap the sweat of one's engagements. Did you prone those platforms you listed there or you just picked them at random? Can they be trusted?
BTW, Binary.com (Now Deriv) also allows for crypto funding for those who trade indices like V75 etc.
