Something’s a bit off here, stake pool
owners/operators don’t have to pledge any 
or even own any to operate a stake pool
If 1,260,056 ADA is the quantity of ADA pledge that Cardano’s protocol dictates is needed to get a stake pool listening displayed to Cardano stakeholders for a potential delegation choice in wallets, then that’s what it is. It doesn’t have to come from stake pool owners, that’s absurd.
