Uniswap launched the long anticipated version 2, and it comes with some neat features.
The whole announcement is here, I just want to highlight the feature I like the most.
Low risk, impermanent loss liquidity provision.
You can now provide liquidity and earn fees on some very low risk pairs, for example

Create a BTC++ (first dETF Bitcoin) + cDAI Pool. You'll earn on cDAI interest, have stability, and you earn trading fees on top.

Or add one of the many Bitcoin flavored tokens.
If you want more inspiration, or an even more complex pooling system, checkout Balancer.
