I did not find any link that says FCA ban bonuses and caped leverage between 1:50. All it says they proposed.
I was searching for lower charged ECN brokers that support account under FCA for traders outside of UK! I found few like Tickmill, they cover most countries except few (8-10 countries) under FCA. They might ask you for some extra papers but I think that’s okay.
However, you should find more at google for reputation.
