My experience with Bunq. My bank is not cryptofriendly so I had to use something in a middle to topup Binance with fiat. I have sent 100 and 500 eur instantly. After I sent 5000 euro and my account was blocked. Normally bank should have asked for documents to prove that funds are coming from legal source. Not the case with Bunq. Not sure if they ever will refund my 5000 euro.
