I need a good multicurrency wallet, and a good bitcoin wallet in the same app.
coinomi supported all the best altcoins, and it was an amazing bitcoin wallet. It supported coin control, sign messages, all address formats and so on.
Coinomi haven't gotten update in a while but all it's features still works well, it hasn't been abandoned. Stick with it, until it stops working altogether.
The problem is that it won't receive updates on new vulnerabilities that might be found.
