It is good that DeFi is being used in new areas that already have many users and are popular. This will more popularize cryptocurrencies and attract many new users to the DeFi market.
But there are also a lot of defi projects that are not really targeting what it use to be.
Everyone has to be careful with those defi projects and if they just want to earn passively, you can choose to have staking coins and just do it on your own without depositing it to any platform.
indeed we have to be selective in choosing coins for staking, otherwise we will be in vain waiting, when the tokens increase, but the price drops, so it actually results in losses. on the other hand for me it is better to invest and put coins in our own wallets, because for the long term the security is entirely in our hands
