If you haven't already joined Coinbase why not give them a go?
You will need to fill in some KYC and AML basics to join
Additional perks include staking DAI (2%) TEZOs (4.67%) and Cosmos (5%). While you can probably find better rates elsewhere (eg Celsius) Coinbase is an all in one platform and once in a while once you've built up enough crypto shift it over. That's what I am doing with my DAI.
