BRD

I like this SPV wallet, mostly because it is connecting directly to Bitcoin nodes from my iPhone, instead of relying on another protocol (ex HTTP) to retrieve the headers. I hope this will be implemented also for Ethereum (is it yet?)

Disclosure, I am CTO of this company. I've stored bitcoin on BRD (previously Bread) for years and never had an issue. We have really good support, so if anyone is having issues we typically respond within an hour or so.

Easy to use, simple, secure, best UI/UX for crypto
