Any suggestions which multicoin wallet to use instead? One of the main reasons I'm still using Coinomi is because I have had it installed for years. I don't like installing new software (because every app can be a risk). But I guess it's time to move on.
Unstoppable wallet.
You are an expert already and you know what close source wallets are, if you need alternative, use Trustwallet if the coins you are looking for is not on unstoppable wallet which is open source.
