I’ll probably say the obvious, but I like using services for sending money where everything’s clear, simple, and visible. Seems like everything should be like this, but I’ve tried a bunch of options and stuck with KoronaPay, like many of my friends, by the way. I like this feature https://koronapay.com/transfers/europe/en/currency-converter/. You can see the rate and fees before sending money. In banks, you always send one amount, and the person gets another after all the fees. It’s not a big deal, but it’s annoying.
