What is the absolute minimum XTZ an address has to own to be able to delegate and receive rewards? Even if this is just a theoretical number and not economically feasible. Assuming the wallet can pay for the transaction fee which is required to set up the initial delegation and at some point send the funds back to the tz1 address.
while technically one can delegate a mutez, the service can't pay out less than a mutez so it's unlikely any payout will be made hence defeats the purpose of delegating.
I think some of the bakers have a minimal limit to the amount they will transfer back, so it's worth paying the fees (unless they do the transfers in one of their baking slots).
一个地址能够委派和获得奖励的绝对最低XTZ是多少?即使这只是一个理论数字,在经济上也不可行.假设钱包可以支付设置初始授权所需的交易费用,并在某个时候将资金退回tz1地址.
