Thanks, I didn't know I could set the fee manually checking it in "settings". Then I probably could have checked this: https://bitcoinfees.earn.com/
and choose a more convenient value.

<p>Yesterday I made my first Bitcoin transaction using Electrum and I was able to configure the fees I was going to pay. As it was a non-urgent transfer I selected the minimum fee Electrum allowed me: "Within 25 blocks", the lowest sat./byte available from the slide bar.</p>

<p>If the transaction was supposed to be included in the next 25 blocks, I thought it will take around 250 minutes (~4hours) to be processed. But I don't know why, after 2hours the transaction already had 6 confirmations.</p>

<p>This minimum fee ended up being 0.0008 BTC (~10 € as the time of writing, which was ~14% of the sent amount).</p>

You can set commision manually in the Electrum settings.

Transactions (with a small or zero fee) which stay unconfirmed for a longer time usually don't get priorized over transactions with a high fee.
Every miner is free to chose which transactions he is going to confirm in his mined block. Its all about how the node is coded to fill the block with TX's.
Since miners mine because they want to gain profit, they will always priorize transactions with a higher sat/B fee.

From me:

> What happens with transaction with zero or low fees?

Generally, after a few days, the transaction will be removed from the mempool and your wallet shows your balance again, which makes your coins
spendable again via wallet.
