ALL BITCOIN WALLETS ARE CUSTODIAL WALLETS ON WINDOWS.

If you're using Stock Google Android, iPhone, and/or Windows,
You're wasting your time with SimpleX, Nostr, Bitcoin, and Monero.

I know you don't want to hear this and the truth is grim.  You can enjoy liking memes and shit, but if your private keys are owned by the adversary:
It's all just for show at that point.

Freedom tech on top of a bad base, is like a skyscraper on quick sand.

But there's hope: Linux is free and you're smart. 

 Stock Google Android: are you talking about hardware? 

Is Google Android but with CalyxOS or Graphene OS safu?
