Total Stakeddivided by the number of BLS keys you set on your validator will give you the effective bidding stake. This effective bidding stake will be used to bid in the 900 slots available each epoch. Bidding above the median stake is the safest way to get your keys elected each epoch. Bidding below the median stake is riskier, as you may be kicked out of the committee for 1 epoch in case you outbid. For more information on the bidding process check here.
