it still shows pending
how can i cancel that payment and resend it with a higher fee??
and should i use dynamic fees in the future or should i set the fee manually for each transaction
i was always very satisfied with electrum but im pissed that it takes so long now to send transactions, especially since i try to trade bitcoins
I think I understand what may have happened...
If you look here
https://blockchain.info/charts/mempool-count you can see that 4 days ago, the transaction volume was very low... Dynamic Fees suggestion would have been low. Then, just as you sent your transaction, the spam attack started and the number of unconfirmed transactions shot up to like 60K+... so everyone started paying higher fees and your transaction got buried
You just got unlucky, no one could really have predicted that the volume of transactions was going to just spike up like that... Electrum can't control people spamming the network... a lot of people using all different wallets will have been caught out by this.
Electrum does have a nifty feature that can help prevent his from happening again tho... make sure that you have "Replace-By-Fee" option enabled for your transactions (Tools -> Preferences -> Fees and make sure that "Propose replace-by-fee" is set to always). That way, in future, should this happen again and you get stuck with a low fee, you can just re-send the transaction with a higher fee
If your transaction is showing in the history as "Replaceable" you can just right click on it and select "Increase the fee"... Ref:
