U are staking BGB which is a volatile asset. Looking at the price from 1 January 2025 (approx $6,00) and price now 4 September (approx $5,00) u lost money in $ amounts.
I think there are better options than staking BGB for Passive Income. There many protocols where u can stake stables and receive similair returns without the volatility
For example I staked USDC on Parcl which netted me alot more and in terms of risks it was betting on housing prices which don't move alot. But it is a one trick so u have to constantly look for new projects where u can stake your funds for a passive income.
