0.45% Fx. And no I don’t see it as concerning, why?
Etoro and 212 have a different business practice, their service isn’t the same and tour assets aren’t as protected. Not to mention 212 are charging a Fx now. You simply cannot offer a service for free.
As to your issue I think the other replies have answered it well. You have the fx fee, and currency fluctuates. There’s no hidden fees been taken.
