Compared to its competitors, I find TenX the most convincing.
The main competitors are XAPO, WIREX, MONACO and TOKENCARD.
Compared to WIXER and XAPO, TenX offers a lower fee to issue the physical and virtual card, no foreign exchange fee and a lower annual fee. The blockchains it operates on are multiple, and not Bitcoin exclusively, and the issuer are both Master Card and VISA.
The main advantage against MONACO and TOKENCARD is that TenX is an advantage because it already has a working app and cards can be requested, while the others seems to be still lagging behind. Moreover both the domestic and foreign transaction fees are cheaper and the user is in full control of the fund security, while for MONACO and TOKENCARD he has to trust the issuer for this matter.
