can anyone explain to me what the hype about TenX card (i participated in the ICO)?

I understand it a card that let you spend your bitcoin. Who other than speculators would be willing to change their Fiat into BTC which fluctuate so wildly. And also, I understand they give 0.5% rebate. In Singapore, they give about 1% rebate for every dollar spend on credit card and you don't need to pay any transaction fee on credit card. Furthermore, it not anonymous as TenX has your details
