Worth noting for Trade Republic is that there is a 1€ fee for every trade you make, unless it’s from a recurring order. To me the app seems more catered to long term savings investments instead of day trading. But I don’t do the latter so who knows. Maybe it works for that end no problem.
Other than that the matching of ECB interest rates on savings is a blessing.
The only thing I’m worried about with them is security. Your username is your phone number and your password is a four digit number. You do get 2FA with the app, but SMS can also be used, which isn’t the safest 2FA from what I know.
Magnet.me is based in The Netherlands. I don’t know how the reach is outside NL but it’s worth a shot maybe?
