there seem to be 5-10 threads a day on r/bitcoin complaining about tiny fees with electrum. maybe it's giving them too much choice.
And then you ask what version they're on and you get "2.5.x"...
Run the latest version (currently 2.8.3)... Tools -> Preferences -> Fees... turn "Dynamic Fees" on... set "Replace By Fee" to "Always"... Then use the slider on the "Send" tab to 'fine tune' the fee as you desire...
If the whole BTC/kB thing is a bit confusing... tick the "Edit Fees Manually" box and a text box appears next to the slider showing the exact fee that has been calculated. PROTIP: DON'T actually manually edit the fee tho!
... or Multibit wallet...
Don't go anywhere near MultiBit HD at the moment... there is a pretty serious error that has been hitting users lately... some folks are getting a "Password did not unlock the wallet" error when starting up, even though the password is 100% correct...
It's been a known issue for at least 2 to 3 weeks now... no sign of an update as yet... Devs don't seem terribly active...
This is locking people out of their wallets, and because MultiBit uses a somewhat 'unique' BIP32 Derivation Path (m/0'/0), there aren't a lot of choices for alternative wallets that are compatible with MultiBit seeds... the only 2 wallets that are currently know to be compatible are "Breadwallet" (on iOS/Android) and "Simple Bitcoin Wallet (Android)...
