69% APY with BTC? In fact, such pairing exists at @MMTFinance. It's even a Vault that manages automatically, and when I checked today, it was showing a 69% APY. This service is provided by Nemo, but there is one downside. The downside is that the pool size itself is very small at 10K, and it is already full. However, since Nemo also utilizes Momentum's LP to create APY, we should take a look at the actual pool size and situation. There shouldn't be any limits there. When I actually entered the LP, I found that if the spread is set to 0.05%, it yields about 11%, and when narrowed down a bit more, it can even reach the 20% range. If the spread is narrowed to around 0.01%, it can even go up to the 190% range, but I expect the actual yield to drop because it will likely go Out of Range too often. It can be anticipated that managing this won't be easy, so in this case, considering a pairing vault based on @WalrusProtocol that collects $SUI and $WAL tokens might be a good option. It actually shows about 100% APY, so if you want to bet on the future of the SUI ecosystem and the representative protocol Walrus, using a strategy that involves point mining and earning APY might not be a bad idea.
