I didn’t even think about how you can “spend” time with others using handhelds. I like this idea :)

While its solid you’re into the efficiency of it all, as an outsider it seems like an added headache to remember which card would be best for which outlet / type of transaction. I personally just maintain a few cards and only switch once I’ve reached about 50-60% the limit.

Proton Mail just has 5 gigs for the free version. Doesn’t seem like it’s enough for me to switch to it long term.
