Advice needed on staking

Hi, I just DeFi staked my ETH for BETH on Binance. They promised an estimated interest of ~ 7-20% or so. I would like to ask however, when will the interest be paid out? In the end of the first phase (when the BETH can be redeemed), or already sooner at some point? Couldn’t find that info easily from the site. Also it would be nice to see the (estimated) cumulative interest somewhere and keep updated about it. Thank you in advance if there’s someone who could help with this! Also: I believe in ETH and will defo buy more later! 💪🏼 🚀
