COINS is a user-friendly app that offers a wide array of popular cryptocurrencies and a simple-to-use app experience. 

It is a smart choice for people who want to have full control of their funds. The app has great features that allow crypto users to store, invest, exchange, send and receive cryptocurrency with a few clicks directly from their mobile device. With built-in non-custodial exchange, COINS members can store, swap and invest crypto-to-crypto from one native app.

Our QA team tested the app to see if any COINS bugs are interfering with its performance.
