yeah, unfortunately so far the cards i know of all have some serious downsides and quite high costs
from the perspective of adoption, almost everyone has phones, and some sort of lightning custodial wallet or semi-custodial LSP based client is easy enough to get... phoenix is pretty good, wallet of satoshi, but that isn't accessible to americans, they can use stuff like phoenix just fine, idk about xapo there but they have lightning built in now, you can receive and make payments with it as well
it's just gonna take time, i guess, and that's the thing, it really needs to be concentrated in small areas, like el salvador and there's that thing in boracay (philippines i think?) and here in madeira
i probably would join in more here if i could live somewhere quiet while not being so far away from where all the community is based in funchal
