thank you very much SebastianJu,
but to use another wallet i have to move the coins there by a tx. how bigger this fee have to be?
if i put 0.0005 btc as fee, then will it work?
thank you.
I can tell you that a day ago i wanted to send a transaction with 10 inputs and three outputs. The suggested fee was 0.00016017 bitcoins.
I don't know how it changes the suggested fee with having more than one output address. I sent all coins, by the way, when you send some coins away from an address so that some coins remain in there, then you would have 2 output addresses too.
I find it strange since some time that no one generated a calculator online for this. Specifying the amount of inputs and outputs and getting a rough estimate for the suggested fee. Should be relatively easy with bitcoin core running on that server.
