I installed https://github.com/mimi89999/Authnkey It is available on f-droid.

So where am I allowed to put my savings? (Outside the fiat system.)

I have tried to find out how the company is doing. I'd like to use more DIEM, but I have no clue if the company is doing well enough to keep it's promise. I started using it because you posted about using it with MOR token, thanks for that.

Pipepipe installed via F-Droid seems to have problems. Pipepipe X installed via Obtanium plays for me. There also seem to be a fix for Pipepipe on Github - haven't tried.

Haven't had any problems with cables, used the ones that came with the Pixels.
