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.
there is not specific amount to pay as fees for sending a transaction. Nowadays, I think sending 0.0001 btc is enough or 0.0002 btc if you want miners confirm the transaction faster
