DislikedFTMO are providing leveraged crypto, you are talking about them connecting to an exchange.Ignored
Most of the brokers that I have spoken to have partnered with Bitfinex, but I assume that there are other exchanges that have partnerships with brokers. You can trade DOT with leverage on Bitfinex, but the leverage is very small.
I suppose that it might even possible to have an aggregate 'feed' across multiple exchanges, but I would be surprised if any brokers have evolved to that level yet.
