It is nice and all but I wouldn't really use my crypto as a payment option when I could use fiat or regular debit card.
I would love to have one but not really sure if I would want to spend my investment when I know that I could use my regular cards to pay and leave my crypto assets to grow.
Might consider it if I don't really have other choice but to spend my crypto.
What about doing the same, but with stables?
And, surely - investment is to grow it, not to spend it like that.
