I am using trading212 now.
Funding via credit card has no advance fee, but the rate really sucks.
I have done my withdrawal last week and the money was reverted into the same credit card as well.
And I also received my reward point after funding.  (Citibank credit card)

My experience so far on this platform.

I used to study in the UK. So I have a digital bank account (Monzo) based in the UK with substantial GBP denominated savings. But I only managed to open a Trading212 account well after my resident pass expired. Hence, I can only choose to fund my account with two base currency, USD or EUR. I used EUR coz I wanted to focus on buying in the European markets.
