I think it would be useful to include in the post how much interest each bank offers. I took a look at some of the banks listed and they are offering 0 interest on money held in their banks. I think it would be good if you include weather the bank accounts are secured by the government in case they go bankrupt to.
I doubt that OP is going to make update. He haven't done it for more than 2 years.
Haven't checked all listed websites, but it's not likely that any of these online banks paying interest. In Europe interest on bank account isn't a thing for long time already. Even if they pay it, rates is such low that's not worth to bother.
And yeah, it would be interesting to know which banks have insured funds in cases of bankrupt.
From what I know, Revolut have insured deposits up to €100 000k. Don't know about others, but probably it wouldn't be difficult to find such information.
