No, not yet. First time I heard of them is here.

thanks for your feedback!

Alby Hub can be used without an email address - but still requires self hosting.

I am interested in this point however, as both cards you use require email address and more. Did you try any no-KYC cards like 2fiat or Freedomia?

Both have a BTC receiving address. I top up with Lightning via boltz swap.

KAST is fine and usually shows within 2-3 confirmations.

Ultimopay has a custodial wallet so I need to sell first, then initiate loading the card which takes up to 24 hours if paying a fee, or up to 72h for no fee.

Keeping a balance. How much depends on how much I expect having to use the card(s).

A combination of NWC friction and not wanting to use Alby.

First and last time I tried to set up NWC, the easiest way was supposed to be with Alby. Still, it was too much friction at just about every step.

As a nomad, I don't run my own node. I tried to use custodial Alby and strongly disliked it requiring me to sign up with an email address.

So, with low confidence in getting the setup done right and not liking the supposedly least-hassle option, I didn't bother to complete it and haven't retried since.

> 1. Do you use a bitcoin/crypto/prepaid card today? Which one?

Yes, as fallback / 2nd last resort.
I have KAST and Ultimopay.

> 2. How do you top it up now? What is the annoying part?

Keeping a balance. How much depends on how much I expect having to use the card(s).
