In addition to owning digital assets, Ethereum enables financial activity via applications built into the platform. Users can use their digital assets inside of Ethereum applications. Trading & exchange, borrowing & lending, derivative and prediction markets are all possible activities on Ethereum that leverage digital assets.
Financial applications on Ethereum can offer basic financial services to those that are not able to access them in their local region. Many Ethereum applications offer savings accounts or investment tools for their users. Unlike traditional financial services like Banks, where you give up ownership over your assets and trust that the Bank will keep them safe, Ethereum applications allow you to retain complete ownership over your digital assets while you use them inside of financial applications.
This all goes for scalability layers like xDai as well.
You can therefore for example exchange and farm your tokens on Levinswap.
