The problem with unconfirmed transactions is only because low fee? or any other reason? I'm use online wallet coinbase and i'm never get problem so far and i want to use electrum for future, What the best fee to get fast confirmation based on amount i sent?
There are other reasons why a transaction can take so long to confirm but low fee is the most common one.
The best fee changes all the time according to the number of unconfirmed transactions and it have very little to do with the amount of bitcoins you're sending. The fee should increase with the transaction size in bytes.
Edit:
The transaction just got confirmed.
