I don't know about TenX. Their apps feel very amateurly coded. They still only support using BTC as a backing currency for your card.

I have a TenX card and used it almost exclusively for an entire week while abroad, it worked fine. I just don't really what see TenX has done differently compared to any other normal BTC based VISA debit card just yet and their app quality doesn't inspire that much confidence in their development team.
