can you tell me the amount of the charge which is applied by the coin base.

3 $ charge for 5$ its too much you will try tomorrow it may reduce charge.
the more charge are apply more when the their is too much queue in the server.
I know that from my own experience. I also tries twice before there was same problem like you. so I want to suggest you to try tomorrow. if the charge is same like today then know that the their charge is too high.

what can i do now?is there any other solution? @magicmusic
