today I waited an extremely long time for tx confirmation.
As a reply above, rebroadcast is the best option when you have unconfirmed transaction or replace-by-fee option, just increase the fee if your transaction generally isn’t processed immediately. If you are using Electrum wallet for this transaction, it could be found on "Tools > Preferences > Fees > Enable Replace-by-Fee".
Much better if we use a small fee for the transaction lets check first in to the Mempool (which is a waiting area for the unconfirmed transaction) If the data shows high Bitcoin unconfirmed, I rather suggest using high fee if you can't wait too long.
As of now, we have high unconfirmed transactions shown on data analysis.
source:I suggest to OP to replace the fee, sometimes acceleration services won't work.
