A lot of these abound. Ranging from passive earning opportunities like staking, farming and lending, newer frameworks like PoolX are currently having a field day. With the PoolX, users are given an opportunity to stake USDT, $BGB & Other alts to mine other good tokens.
Let me know what you think about these kinds of ways to earn.
This is same with the traditional staking feature since the mechanics is just the same user lock their tokens in exchange for mining different tokens. You can do this feature on Beefy finance and other DEFI that focus on optimizing pools.
Staking is indeed one of the safest feature on crypto to earn but you can up still on loss even after gaining passive profits if your main tokens stake decreases in price. Even stablecoins sometimes depegged below 1 dollar so this method is still not 100% safe from risk.
Casino staking is one method too on gaining passive profit since they use their casino profit to distribute for investors stake money.
