I can not send my bitcoin to external wallet

i can not send my bitcoin to external wallet.how much does it cost to minner?and how much minimum amount?please teach me.i try to do your suggest on the web site and i read topic.

If you send BTC from counterwallet, you can simply click on send in the BTC asset. Then an overlay appears, where you can enter target address and amount. There’s also an option MAX, to send all you have. Take note that a fraction of BTC is used for fees. (0.0002 BTC if I recall correctly). So mimimum amount is anything above 0.0002 BTC.
