The interest from @multiplifi that gets updated every Friday. I am currently in a state where I have deposited my $BTC held on the EVM into Multiplifi. Of course, I could also deposit using $LBTC and put it into the Vault, but for now, I am depositing wBTC directly into Multiplifi and mining at an annual 5% APY. The BTC deposited this way generates yield every day, but the actual reflection on the front end is only visible on Friday afternoons. The snapshot point is right on that Thursday of the week. Previously, it was operated with daily changes, but at some point, it switched to weekly updates. Personally, I don't really like this weekly update. I have a feeling that it might have been done to prevent backend update cycles or system load, but I personally think that at least it should be updated on a daily basis, even if it can't be in real-time. Anyway, the accumulated interest is stacked as BTC, which is an advantage, but when withdrawing it, it takes up to 10 days, so for small amounts, it is somewhat beneficial to wait a bit. Otherwise, the claim fees and staking fees will be higher. (Because it's on the Ethereum chain...) Anyway, I am gradually increasing the amount of BTC I hold by using the existing BTC in a way that feels like DCA.
