To be honest with you, I would never consider using your app. This is due to the countless horror stories I've heard over the years from your users. It must be a very profitable business model for you to just seize any user's coins you see fit, and then only sometimes release them after the victim has complained very publicly and loudly about the theft.

For people looking for a good multi-coin wallet, I would gladly recommend Trust Wallet for mobile devices and Exodus for desktop. I know there's others but in all my years in crypto I've never had a problem with either one of those.
