I am using Bitcoin Wallet v5.09-v5.10 on Android 6.0.1. Is there a way to lower the Bitcoin transaction fee?
Yes, use Send Coins > Options > Fee to select one of three fee levels. The actual fee is dynamic and depends on the byte size of your payment. Use
- Priority if a payment is urgent
- Normal if you want confirmation roughly within the next hour
- Economic if you don't care about confirmation times (mostly if you're sending to another wallet of yours)
