Hi Everyone, I am Gabriele, CEO and cofounder of Coinrule. Happy to answer any of your questions.
With fixed fee pricing we are seen by regulators as a Software provider rather than a trading platform. The other point is that user funds sit on the exchanges and we have no withdrawal rights for greater account safety, so it's easier for us to just charge a fixed fee.
Is this a well established rule? I had a few startup ideas related to fintech, and this would be a very interesting change in the value proposition.
