Coinbase is the best option. I think the notion that stablecoin supply going up == defi tvl going up is not accurate. We will start to see defi tvl go up once we have more than a single soverign debt dominating the stablecoin space, because that means there will be a demand for fx swaps. Until then, there is no demand for fx swaps and hence the trickle down effect to defi will be very very low, mostly going to lending markets and not swap markets.
