So, which do you think is better—savings or staking?
I better put investment against staking rather than staking. For a speculative asset that changes in value and I've done my research on the fundamentals I'll rather invest it while I maintain self custody of the asset than to stake with a service that holds custody of my assets.
If you're willing to take the risk and can do your due research on which staking service to use, that can be a good option for you over investing.
Savings should always hold a certain amount of your worth and that should not be substituted.
