No, as with Ryanair booking itself, the card fees are avoidable if you play it to the letter. But if you hand over money to this bank, and they do go under, you have lost all you put on the card, and that is what I understand happened with the last provider.
This card was initially going to be issues by a subsidiary of MasterCard, which would have been safe, now it is with a relatively unknown private bank, who might have been around for a couple of hundred years, but so were Barings.
