" needs to step it up. Their website hasn't been updated in ages. Lots of features are broken/not working (what happened to firstbits, shared send is broken, etc). The new Android mobile app is also buggy as #$%^&. Not sure who's running the show there, but they should step it up."

Another user added:

" was the first wallet I used after starting with Bitcoin Core and I loved it. It was so simple yet powerful.

A lot has changed since then, as they have had trouble scaling and meeting increased customer demand. My biggest issue is stability, which is huge when you are offering a financial service."
