there are a lot of countries which aren't supported yet. However, AFAIK all the VISA crypto debit cards like tenx are dead and not working at the moment. The NAGA debit card is a MASTERCARD. So this is the only debit card which actually works right now. It also includes a virtual credit card so you can buy things online using this credit card. Anyhow anyone interested in spending his crypto gainz anywhere with a credit card should definitely take a look! Thanks for the share @pkalra
