When I try to spend about 4.7 mbtc I get an error message : "Balance not enough". I deduce that network fees should be around 4mbtc, which is kind of high. My balance formed from around 15 faucet inputs 0,5 mbtc each on single adress, so I think that is the source of my problem.
What should I do now? 1. Does "economical" transfer of these inputs on new address gives me lower fees after that or not? 2. Should I move my balance to other app, or this is not BitcoinWallet problem and any other app give me same fees?
