It's better if you stake in not only 1 stable coin but multi ones to reduce the risk in case something happened to that stable coin. There is plenty of stable coins offered staking like BUSD, USDD, DAI,.. You should spread out over them.
It is a good idea to stake more than one stablecoin for security purpose but it is equally important to chose a reputable platform with proven track record to stake where investors funds are secured and guaranteed.
Also if the funds in question is small, splitting them on multiple stablecoins won't bring a reasonable reward since the apy of stablecoins are usually smaller than normal altcoins staking so if the @op decided to split the funds into different stablecoins it won't generate good reward.
However, if @op also wants to stake some good altcoins for a reasonable reward - (
an average of 14.98% apy)
